QField at FOSS4G 2025 Auckland: From Mobile App to Production Infrastructure

Throughout the week, in workshops, presentations, and project showcases, a consistent theme emerged: QField is not just « the mobile companion to QGIS, » it is production infrastructure for complete field-to-cloud-to-desktop workflows. It was incredible to see how present QField was throughout FOSS4G 2025 in Auckland. With around 20 presentations and workshops featuring QField, the conference showcased a wide range of real-world, production-grade use cases across many sectors. What stood out was not just the number of talks, but how consistently QField was presented as a trusted, operational tool rather than an experiment.

QField 4.0 “Aare”: Unlocking a great spatial experience for a larger audience – OPENGIS.ch

Wed, 17 Dec 2025 00:00:00 +0100

Just in time for the end of 2025, QField 4.0 is now available in a virtual store near you. This release brings significant improvements and marks an important usability milestone, worthy of a new major version. It’s truly never been easier to get started with QField—whether you’re a seasoned GIS professional or new to spatial data collection.

Main highlights

One of the most significant feature additions in this new version is right there on the welcome screen: a simple wizard for creating new projects. The wizard guides users through a set of questions covering the desired basemap style and actions such as note taking and position tracking. These projects can be published directly on QFieldCloud, so users can upload images, notes, and tracks that are accessible through web browsers or QGIS using QFieldSync. The project creation framework also unlocked another feature we’re proud of: on-the-fly conversion of imported projects to cloud projects. The ability to upgrade pre-existing projects to cloud projects means that users can push spatial data and attachments residing on their devices to QFieldCloud and instantly collaborate with coworkers. On the QFieldCloud front, we’ve done significant code refactoring to make synchronization and attachment uploads even more reliable. Users now see a progress bar showing attachment upload status. The cloud projects list also lets users push changes and sync projects without opening them first. Indicator badges show whether you have pending local changes or if updates are available from the cloud.

Looking at recent QFieldCloud storage handling improvements – OPENGIS.ch

Thu, 09 Oct 2025 00:00:00 +0200

Our ninjas have been hard at work improving QFieldCloud! In recent versions, a series of functionality improvements have had a significant impact on the way QFieldCloud handles storage, and we want to tell the world! Without further due…

Shared datasets

Starting with version 3.6, QField supports shared datasets. Known in QGIS as “localized data paths”, this allows users to upload a single instance of a given dataset to QFieldCloud and have it embedded within multiple cloud projects. For large datasets such as satellite imagery or topo basemaps, the benefits include:

QField 3.7 “Haida Gwaii”: Polishing a great experience – OPENGIS.ch

Mon, 04 Aug 2025 00:00:00 +0200

For QField 3.7, we opted for a shorter development cycle that focused on polishing preexisting functionalities from feature form editor widgets improvement through to better nearby Bluetooth device discovery. Of course, we couldn’t help ourselves and still packed in some nice functionality that we thought deserved to reach QField’s growing community as soon as possible.

Main highlights

One of the most interesting new functionalities from this development cycle has been the ability to stamp details on photos taken by QField’s in-app camera. A basic version of this has been supported for a while now; this new version offers flexible customisation of details stamping onto photos, including changing the font size, colour, and horizontal position, as well as providing users with the ability to completely change the details via expression-driven templates and add image overlays onto the photo. The custom details stamping configuration lives within project files, allowing for individual projects to drive styling and details. The configuration interface is provided by QFieldSync and can be found in the project properties dialog by switching to the QField panel when setting up projects in QGIS: The other significant addition in this release is the new plugin manager’s Available Plugins tab, which offers a curated list of plugins that can easily be installed with a single tap. The list makes it much easier to discover plugin-delivered functionalities such as online routing, geocoding searches, and much more. The plugin manager can also alert users of available updates for their installed plugins, ensuring that crucial bug fixes and improvements are easily delivered. When a new version is released, users can update via a single tap. We are looking into the possibility of enabling automated plugin upgrades soon. Long-time users of QField are probably aware of a nifty feature that allowed individual project layers to be locked, and for that lock to be driven by a data-defined property expression. For this new version, we’ve supercharged the layer lock functionality by breaking it down into four distinct vector layer permissions that can be disabled: i) feature addition, ii) attribute editing, iii) geometry editing, and iv) feature deletion. These permissions can be disabled by activating a checkbox or conditionality turned on via a data-defined property expression. The disabling of permissions using a data-defined property expression allows for interesting scenarios when paired with QField-driven expression context variables such as the user name of a logged-in QFieldCloud account (@cloud_username), GNSS positioning (@gnss_coordinate) and more. Users can easily restrict permissions based on the user interacting with a cloud project, or form advanced geofencing-like rules based on location, time of the day, etc. For more details on available variables, read this page on QField’s growing documentation site.

QField 3.6 “Gondwana”: Locking on greatness – OPENGIS.ch

Tue, 03 Jun 2025 00:00:00 +0200

Building on top of the last release which introduced background tracking, this development cycle focused on polishing functionalities and building on top of preexisting features. The variety of improvements is sure to make our diverse user base and community excited to upgrade to QField 3.6.

Main highlights

One of the most noticeable improvement in this version is the addition of “map preview rendering”. QField now renders partial map content immediately beyond the edge of the screen , offering a much nicer experience when panning around as well as zooming in and out. Long-time QGIS users will recognise the behaviour, and we’re delighted to bring this experience to the field This upgrade was the foundation upon which we built the following enhancement: as of QField 3.6, using the “lock to position” mode now keeps your position at the very center of the screen while the canvas slips through smoothly. This greatly improves the usability of the function as your eyes never need to spend time locating the position within the screen: it’s dead center and it stays there! Reminder, the “lock to position” mode is activated by clicking on the bottom-right positioning button, with the button’s background turning blue when the mode is activated. The improvements did not stop there. Panning and zooming around used to drop users out of the lock mode immediately. While this had its upsides, it also meant that simple scale adjustments to try and view more of the map as it follows the position was not possible. With QField 3.6, the lock has been hardened. Moving the map around will temporarily disable the lock, with a visual countdown embedded within a toast message informs users of when the lock will return. An action button to terminate the lock is located within the toaster to permanently leave the mode. Moving on to QFieldCloud, this cycle saw tons of improvements. To begin with, it is now possible to rely on shared datasets across multiple cloud projects. Known as localised data paths in QGIS, this functionality enables users to reduce storage usage by storing large datasets in QFieldCloud only once, serving multiple cloud projects, and also easing the maintenance of read-only datasets that require regular updates. QFieldSync users will see a new checkbox when synchronising their projects, letting them upload shared datasets onto QFieldCloud. Furthermore, QField has****introduced a new cloud project details view to provide additional details on QFieldCloud-hosted projects before downloading them to devices. The new view includes a cloud project thumbnail, more space for richer description text, including interactive hyperlinks, and author details, as well as creation and data update timestamps. Finally, the view offers a QR code, which allows users to scan it quickly and access cloud projects, provided they have the necessary access permission. Distributing a public project has never been easier! Beyond that, tons more has made its way into QField, including map layer notes viewable through a legend badge in the side dashboard, support for feature identification on online raster layers on compatible WMS and ArcGIS REST servers, atlas printing of a relationship’s child feature directly within the parent feature form, and much more. There’s something for everybody out there.

XLSForm Converter: unlock a world of surveys with our brand new QGIS plugin – OPENGIS.ch

Mon, 02 Jun 2025 00:00:00 +0200

Today marks the initial release of our brand-new QGIS plugin, XLSForm Converter.
As the name suggests, the plugin converts XLSForm survey files into ready-to-use QGIS projects with a preconfigured survey attribute form. Migrating to QField was never easier!

Even more exciting is that the converted QGIS project includes all the necessary settings for use with QField, thanks to a nifty QFieldCloud integration. With just a single checkbox, you can upload your generated project to the cloud and begin gathering data—either as a standalone surveyor or collaboratively as part of a team. We believe this provides a fantastic solution for organisations and groups familiar with XLSForm—or already working with templates—who want to leverage QGIS-powered QField to conduct spatial surveys.

A brief look into our QGIS Processing Workshop – OPENGIS.ch

Tue, 25 Mar 2025 00:00:00 +0100

In the afternoon of our 10 year anniversary, a mixed group of experienced QGIS users and developers from OPENGIS.ch got together to take a close look at the Graphical Modeler tool in QGIS. Example of a processing model This tool is not known, let alone used by all QGIS users. In an initial round of feedback on the current functionalities, it became clear why: the GUI is not intuitive, it is cumbersome, unresponsive and misses someessential features. Of course, not all is negative. The tool already allows for some very complex chaining of processing algorithms. But it could be so much more and offer its potential to a much wider user community. Initial feedback round The goal of this workshop was to identifyspecific pain points of the current version, collect ideas for improvements and definepriority actions. Based on the first feedback round, the participants easily agreed on three main work topics: Graphical User Interface (GUI), Integration within QGIS and Productivity. This led to the following questions:

Unpacking key insights from our QField Workshop – OPENGIS.ch

Tue, 25 Mar 2025 00:00:00 +0100

This year, OPENGIS.ch celebrated its 10th anniversary in Bern, with an afternoon full of workshops attended by clients, long-term friends, and colleagues. Here, we will give a glimpse of QField: its vision, where it’s headed , and the exciting features future users can look forward to. QField was created on June 8th, 2011, with its first commit titled “ added first script ”. Since then, it has grown into a powerful tool with a clear vision for the future: to empower people to map and understand the world, tackle daily challenges, and address global issues. Over the next ten years, QField aims to make this vision a reality for everyone, everywhere. Layers of cake, designed by QField ecosystem’s leading team members, were explained with 2034 in mind: intuitive and accessible to anyone wanting to map our world, while pioneering an innovative and collaborative app for the geospatial community. And last but not least: building strong and engaged communities to drive further adoption of the QField ecosystem. This vision is taking shape through the forging of strategic partnerships with geospatial stakeholders: hardware manufacturers, ambassadors, trainers and technological partners. For the team, it is clear that good collaboration is key to building a healthy and sustainable ecosystem. Community as well as financial sustainability can become a strong reality with user groups, sponsors and crowdfundings. And then it became reality: In the summer of 2024, heavy rains caused severe flooding in Switzerland and, suddenly, QField became a vital tool for supporting emergency response through data surveys and photo documentation. With this emotional story, the technical lead, Mathieu took over and shared other QField success stories andseveral mapping use cases with partners in Finland and Tonga. But seamless fieldwork wouldn’t be possible without QFieldCloud, so Ivan provided an insight into the last years’ QFieldCloud enhancements , before diving into the busy server-side roadmap for 2025, which includes many new features related to the authentication, security, internationalization and performance. Finally, Zsanett shared QField product news and updates , including new storage capacities like WebDAV and new packaging capabilities. Last but not least, the new Fangorn version introduces new features developed by the evolving QField Community. Building communities by sharing thoughts and ideas for the ecosystem is now possible through the ideas.qfield.cloud platform, open to everybody to suggest new ideas for QField. The final topping of the (layer) cake: the new QField plugin framework was presented to the workshop attendees by Mathieu, who explained how the field workflow can be enhanced and optimized through the development of plugins – unique extensions that further personalize QField. For example, with the Routing Plugin, users can compute optimal ways between locations directly in QField using an external API. To make team efforts in the field even more efficient , the Live Location Plugin allows each team member to see the location of other members on the QField map, preventing debilification in the field. Last but not least, the workshop ended with a Q&A session, where several topics were addressed such as virtual reality, AI, machine learning, etc. This was followed by a happy and cheerful welcome drink with OPENGIS.ch partners. 🍻

QField 3.5 “Fangorn”: Background tracking a reality! – OPENGIS.ch

Tue, 04 Mar 2025 00:00:00 +0100

Let’s not bury the lead here: the long-awaited capability to track position while QField is in the background or the device is locked has arrived in this brand-new version of QField. This feels like a magical moment, so we settled for a fantastical forest for our release name.

Main highlights

As highlighted above, QField 3.5 has unlocked background position tracking on the Android platform. This allows users to keep track of their positions even as they put QField in the background to conduct other tasks on their devices. It also means that tracking has become far more battery efficient, as users can lock/suspend their phones and tablets for long periods while QField continues to collect and track positions. On top of it all, this will work out of the book with internal GNSS as well as external high-precision GNSS devices. This is a long-requested functionality for QField, and we couldn’t be prouder to deliver it to our hundreds of thousands of Android users. Big thanks to Groupements forestiers Québec, Biotope, and Terrex Seismic, who jointly sponsored the development. Moving on to the next major feature added to this new version. Users can now easily import folders from WebDAV services and subsequently upload and download content to that remote folder within QField itself. This functionality eases friction on Android and iOS platforms where storage access is heavily regulated. This implementation highlights our commitment to providing QField users with the freedom they need to build their workflows; thanks to Prona Romandie, AgaricIG, and Oslandia for commissioning this work. It’s important to note that the WebDAV functionality does not provide data synchronization. The download and upload operations will overwrite datasets stored locally or remotely. For users in need of synchronization and smooth project distribution, QFieldCloud is the way to go. With this new version of QField, downloading large datasets from QFieldCloud has become much more reliable, especially on devices with low memory. Last but not least, QField has gained support****for project-configured grid decoration. When activated, a grid is overlayed on top of the map canvas, which will dynamically render while panning and zooming around. The grid is configured and activated while setting up projects within QGIS itself. Pro tip: this functionality can replace heavy grid datasets when covering a large dataset, something to consider when trying to optimize projects’ storage size. Big thanks to Oester Messtechnik GmbH for supporting the implementation of this fourth decoration following the arrival of title, copyright, and image decorations in earlier releases. Other improvements in this release include “forward” angle snapping to digitize perfectly angled polygons, pinch gesture-driven feature rotation , and a new print template which unlocks printing of map canvas to PDF even when their projects have no layouts defined.

Visualizing Ideas: From circles to planets to story arcs – OPENGIS.ch

Tue, 14 Jan 2025 00:00:00 +0100

My first day at OPENGIS.ch back in September wasn’t what you usually expect when starting at a new workplace. Instead of diving head first into some complex code repository or reading up on company policies, I found myself scribbling lines and circles onto paper. The OPENGIS.ch team was meeting in Bern atPuzzle ITC / We Are Cube for a workshop on visualizing ideas, hosted by Mayra and Jürgen from We Are Cube. For a few hours, a room full of slightly unsure, but mostly intrigued geo ninjas armed with pencils and paper discovered a new way to express their ideas through simple visuals.

Des lieux pollués en GeoPackage – OPENGIS.ch

Tue, 03 Dec 2024 00:00:00 +0100

Implémenter et modifier le modèle fédéral INTERLIS du cadastre des sites polluésKbS_V1_5 sans problème dans un GeoPackage ? Un rêve lointain pendant longtemps, mais désormais réalité. Avec Model Baker 7.10 et ili2db 5.2, vous pouvez maintenant travailler confortablement avec vos ensembles de données INTERLIS contenant plusieurs colonnes de géométrie par classe dans un GeoPackage. Un point de douleur qui existe depuis des années dans le traitement de modèles comme celui du cadastre des sites pollués ou de la planification de l’utilisation, c’est que les modèles contiennent des classes avec plusieurs géométries. Par exemple, ici, une géométrie de type point et une géométrie de type polygone.

Modèles de traduction en QGIS Model Baker – OPENGIS.ch

Tue, 12 Nov 2024 00:00:00 +0100

**La semaine dernière, les participant·e·s de la journée INTERLIS à Yverdon-les-Bains ont pu tester la toute nouvelle version expérimentale duQGIS Model Bakers Version 7.10. Et par la même occasion, l’implémentation de la gestion des modèles de traduction. Un plaisir pour toutes les régions linguistiques de la Suisse. ** La Suisse est quadrilingue et c’est magnifique. En tant que Suisse alémanique, je maîtrise à peine 1,75 de ces langues, mais j’écoute volontiers la sonorité et la poésie des trois autres. En revanche, en tant que passionné de technologie, je souhaite parfois une norme, un standard, une seule langue. Mais laquelle choisir? Je ne suis probablement pas seul à ressentir ce besoin d’une seule langue, car la plupart des modèles de données géographiques minimaux (MGDM) de la Confédération sont en allemand. «Pourquoi en allemand?», m’a demandé ma collègue de Suisse romande.
«Dans quelle langue devraient-ils être?», ai-je répondu.
«En français, bien sûr!», a-t-elle rétorqué. Lors d’une séance d’assistance à un service fédéral pour la modélisation INTERLIS, nous nous étions mis d’accord pour écrire les modèles en anglais. L’anglais est la langue technique et ne discrimine aucune des langues nationales suisses. Plus tard, j’ai rencontré un utilisateur d’INTERLIS venant du Tessin qui m’a dit:
«Pourquoi en anglais? Dois-je maintenant comprendre l’allemand et également l’anglais?» C’est donc un sujet sensible.

QField 3.4 “Ebo”: Geofencing and processing out of the box – OPENGIS.ch

Tue, 08 Oct 2024 00:00:00 +0200

QField 3.4 is out, and it won’t disappoint. It has tons of new features that continue to push the limits of what users can do in the field.

Main highlights

A new geofencing framework has landed, enabling users to configure QField behaviors in relation to geofenced areas and user positioning. Geofenced areas are defined at the project-level and shaped by polygons from a chosen vector layer. The three available geofencing behaviours in this new release are:

QGIS Swiss Locator 3.0 brings elevation profiles and vector tiles – OPENGIS.ch

Tue, 25 Jun 2024 00:00:00 +0200

Swiss elevation profiles

Get high-precision elevation profiles in QGIS right from Swisstopo’s official profile service, based on swissALTI3D data! Swiss elevation profiles are available with QGIS 3.38. Thanks to this integration, you can take advantage of existing QGIS features, such as exporting 2d/3d features or distance/elevation tables, as well as displaying profiles directly in QGIS layouts. Tip : Swiss elevation profiles will be available as long as the Swiss Locator plugin is installed and active. Should you need to turn Swiss elevation profiles off to create other profiles with your own data, go to the Plugin manager and deactivate the plugin in the meantime.

Journée des utilisateurs QGIS Suisse 2024 – du point de vue d’OPENGIS.ch – OPENGIS.ch

Thu, 20 Jun 2024 00:00:00 +0200

Pendant la pandémie, nous avons remarqué à quel point le travail à distance pouvait être efficace, à quel point les visioconférences pouvaient être productives et à quel point les webinaires fonctionnaient bien. Au sein d’OPENGIS.ch, ce n’était pas une nouveauté car nous travaillions déjà à 100% à distance. Mais ce qui nous a vraiment manqué, comme la plupart des gens dans notre secteur, c’était de rencontrer les parties prenantes en personne, de se réunir, de réseauter et d’échanger des idées sur un sujet commun. Pas lors de réunions planifiées, mais dans des discussions ouvertes, autour d’un café, sur le chemin des toilettes, en prenant l’air ou lors d’une bière après le travail au soleil. Nous sommes donc très heureux que la Journée des utilisateurs QGIS Suisse ait eu lieu pour la deuxième fois depuis lors, la semaine dernière. OPENGIS.ch s’est investi dans QGIS depuis sa création, en fait même avant; notre PDG Marco a commencé à travailler avec QGIS 0.6 en 2004 et notre CTO Matthias avec la version 1.7 en 2012. Et depuis 2019, nous sommes l’entreprise avec le plus grand nombre de contributeurs core de QGIS. Nous pouvons définitivement dire qu’OPENGIS.ch a été l’un des principaux moteurs de l’adoption massive de QGIS en Suisse et dans le monde. En termes de contribution au code de QGIS, nous sommes de loin l’entreprise la plus prolifique en Suisse et la deuxième au monde, juste derrière North Road Consulting. De plus, nous avons été la première – et sommes toujours l’une des deux seules – entreprises à soutenir QGIS.org à un niveau Large depuis 2021. Cela nous rend très fiers et c’est pourquoi nous sommes encore plus heureux de voir à quel point ce qui se passe autour de QGIS en Suisse s’aligne avec les visions et les objectifs que nous nous sommes fixés il y a des années. La journée a commencé par une présentation de notre CTO Matthias Kuhn « Quoi de neuf dans QGIS » mettant en avant de nombreux travaux sponsorisés par le Groupe d’utilisateurs suisse. Les améliorations de DXF, la sortie de SwissLocator 3.0 avec l’intégration de swissalti3d et des tuiles vectorielles, ainsi qu’une mise à jour sur les avancements dans la gestion des arcs de cercle dans QGIS, une condition préalable à la gestion correcte des données de la mensuration officielle en Suisse, étaient quelques-uns des points forts. Le highlight secret de la présentation de Matthias était une meilleure intégration des API OGC dans QGIS, qui a également été soulignée dans une présentation ultérieure sur Kablo, montrant comment la prochaine génération des modules métier pourrait être mise en œuvre.

Supercharge your fieldwork with QField’s project and app-wide plugins – OPENGIS.ch

Tue, 18 Jun 2024 00:00:00 +0200

This blog post will introduce QField’s brand new plugin framework and walk through the creation of a plugin to support bird watchers in need of a quick way to digitize photos of spotted birds onto a point vector layer. QField Plugin Snap! in action

A plugin framework is born!

As announced recently, QField now empowers users through a brand new plugin framework allowing for simple customization on the way the application behaves or looks all the way through to creating completely new functionalities. The plugin framework relies on Qt’s QML engine and JavaScript, allowing for cross-platform support out of the box. This means that plugins will run perfectly fine on all platforms currently supported by QField: Android, iOS, Windows, Linux, and macOS.

QField 3.3 “Darién”: It is just the beginning – OPENGIS.ch

Tue, 11 Jun 2024 00:00:00 +0200

QField 3.3 has been released, and with it, we are proud to introduce a brand new plugin framework that empowers users to customize and add completely new functionalities to their favourite field application. That’s on top of a bunch of new features and improvements added during this development cycle. What preceded this moment was just the beginning!

Main highlights

One of the biggest feature additions of this version is a brand new drawing tool that allows users to sketch out important details over captured photos or annotate drawing templates. This was a highly requested feature, which we are delighted to bring to all supported platforms (Android, iOS, Windows, macOS, and, of course, Linux) with the financial support of the Swiss QGIS user group. Also landing in this version is support for copying and pasting vector features into and from the clipboard. This comes in handy in multiple ways, from providing a quick and easy way to transfer attributes from one feature to another through matching field names to pasting the details of a captured feature in the field into a third-party messenger, word editing, or email application. Copying and pasting features can be done through the feature form’s menu as well as long pressed over the map canvas. If copy pasting ain’t your style, a new feature-to-feature attributes transfer shortcut has also been added to the feature form’s menu. Appreciation to Switzerland, Canton of Lucerne, Environment and Energy for providing the funds for this feature. The feature form continues to gain more functionalities; in this version, the feature form’s value map editor widget has gained a new toggle button interface that can help fasten data entry. The interface replaces the traditional combo box with a series of toggle buttons, lowering the number of taps required to pick a value. If you enjoy this as much as we do, send a virtual thanks to German Archaeological Institut – KulturGutRetter, which sponsored this feature. Other improvements in the feature form include support for value relation item grouping and respect forthe vector layer attributes’ « reuse last entered value » setting. Finally, additional features that are sure to please include support for image decoration overlay , a new interface to hop through cameras(front, back, and external devices) for the ‘non-native’ camera**,** the possibility todisable the 3-finger map rotation gesture , and much more.

QField receives prestigious recognition as a digital public good from the Digital Public Goods Alliance – OPENGIS.ch

Thu, 06 Jun 2024 00:00:00 +0200

We are thrilled to announce that theBest of Swiss AppsEnterprise winner 2022, QField, has been officially recognized as a Digital Public Good by the UN-endorsedDigital Public Goods Alliance. This prestigious recognition highlights QField’s significant contributions to six key Sustainable Development Goals (SDGs): SDG 6 (Clean Water and Sanitation), SDG 9 (Industry, Innovation, and Infrastructure), SDG 11 (Sustainable Cities and Communities), SDG 13 (Climate Action), SDG 15 (Life on Land), and SDG 16 (Peace, Justice, and Strong Institutions). The “Swiss Made Software” QField is the leading fieldwork application with almost 1 Million downloads worldwide.

The PostgreSQL Connection Service File and Why We Love It – OPENGIS.ch

Tue, 28 May 2024 00:00:00 +0200

The PostgreSQL Connection Service Filepg_service.conf is nothing new. It has existed for quite some time and maybe you have already used it sometimes too. But not only the new QGIS plugin PG service parser is a reason to write about our love for this file, as well we generally think it’s time to show you how it can be used for really cool things.

What is the Connection Service File?

The Connection Service File allows you to save connection settings for each so-called “service” locally. So when you have a database called gis on a local PostgreSQL with port 5432 and username/password is docker/docker you can store this as a service called my-local-gis.

QGIS DXF Export enhancements – OPENGIS.ch

Mon, 13 May 2024 00:00:00 +0200

At OPENGIS.CH, we’ve been working lately on improving the DXF Export QGIS functionality for the upcoming release 3.38. In the meantime, we’ve also added nice UX enhancements for making it easier and much more powerful to use! Let’s see a short review.

DXF Export app dialog and processing algorithm harmonized

You can use either the app dialog or the processing algorithm, both of them offer you equivalent functionality. They are now completely harmonized!

Status of Cloud Optimized Geospatial Formats – OPENGIS.ch

Tue, 09 Apr 2024 00:00:00 +0200

Cloud-optimized formats are changing how we handle geospatial data, making it easier to access and work with large datasets directly in the cloud. These formats reduce the need to download entire datasets, facilitating quicker and more focused data analysis and visualization. For those interested in the specifics of these advancements, our recent Cloud Optimized Geospatial Formats – Status Report, offers an introduction into the topic, recommendations for usage and an overview of promising formats. Within this project, we also released a sample of various tiles downloaded from swissSURFACE3D as a single cloud optimized point cloud file and made it accessible also via a potree powered web viewer that demonstrates how one single file can be used for visualization in the web and making accessible for applications like QGIS and QField via the direct access URL . I would like to thank GeoStandards.ch and SGS to allow us working on this. We’re keen to hear from you as well. Please share your experiences or additional insights and formats in the comments.

QField 3.2 “Congo”: Making your life easier – OPENGIS.ch

Thu, 04 Apr 2024 00:00:00 +0200

Focused on stability and usability improvements, most users will find something to celebrate in QField 3.2

Main highlights

This new release introduces project-defined tracking sessions, which are automatically activated when the project is loaded. Defined while setting up and tweaking a project on QGIS, these sessions permit the automated tracking of device positions without taking any action in QField beyond opening the project itself. This liberates field users from remembering to launch a session on app launch and lowers the knowledge required to collect such data. For more details, please read the relevant QField documentation section. As good as the above-described functionality sounds, it really shines through in cloud projects when paired with two other new featurs. First, cloud projects can now automatically push accumulated changes at regular intervals. The functionality can be manually toggled for any cloud project by going to the synchronization panel in QField and activating the relevant toggle (see middle screenshot above). It can also be turned on project load by enabling automatic push when setting up the project in QGIS via the project properties dialog. When activated through this project setting, the functionality will always be activated, and the need for field users to take any action will be removed. Pushing changes regularly is great, but it could easily have gotten in the way of blocking popups. This is why QField 3.2 can now push changes and synchronize cloud projects in the background. We still kept a ‘successfully pushed changes’ toast message to let you know the magic has happened 🚀 With all of the above, cloud projects on QField can now deliver near real-time tracking of devices in the field, all configured on one desktop machine and deployed through QFieldCloud. Thanks to Groupements forestiers Québec for sponsoring these enhancements. Other noteworthy feature additions in this release include:

Snappy QField 3.1 “Borneo” has arrived – OPENGIS.ch

Wed, 10 Jan 2024 00:00:00 +0100

The launch of QField 3.0 was a big deal, but now we’re back to focusing on smaller, more frequent updates. Don’t let the shorter change log for 3.1 trick you – there are lots of cool new features in this update!

Main highlights

One of the main improvements in this release is the brand-new functionality to enable snapping to common angles while digitizing. When enabled, the coordinate cursor will snap to configured angles alongside a visual guideline. This comes in handy when adding new geometries while surveying features with regular angles (e.g. buildings, parking lots, etc.). As QField gets more digitizing functionalities, we’ve taken the time to implement a nifty UI that collapses digitizing toggle buttons into a drawer,leaving extra space for the map canvas to shine through. In addition, the vertex editor – one of QField’s most advanced geometry tools – received tons of love during this development cycle, focusing on improving its usability. Changes worth mentioning include:

Traquer en arrière-plan sur QField – OPENGIS.ch

Wed, 20 Dec 2023 00:00:00 +0100

Il y a quelques années, la communauté QField et ses utilisateurs ont montré leur amour pour leur application de terrain préférée en soutenant un crowdfunding réussi pour améliorer la manipulation de l’appareil photo. Depuis lors, OPENGIS.ch a continué à diriger le développement de QField avec le soutien régulier de sponsors. Nous ne pourrions être plus fiers des progrès que nous avons réalisés, avec de nombreuses nouvelles fonctionnalités ajoutées dans chaque version majeure. Il s’agit notamment d’améliorations majeures en matière de positionnement, y compris le suivi de la localisation, l’intégration de récepteurs GNSS externes par le biais non seulement de Bluetooth, mais aussi de connexions TCP/UDP et de ports série, d’indicateurs et de contraintes de précision et, plus récemment, de lecture de capteurs, pour n’en citer que quelques-uns. Nous faisons maintenant appel à la communauté pour nous aider à améliorer QField et à franchir une étape importante : le service de localisation en arrière-plan. S’engager maintenant

Les modèles INTERLIS étendus dans QGIS – OPENGIS.ch

Tue, 31 Oct 2023 00:00:00 +0100

Le lancement deQGIS Model Baker Release 7.6 est arrivé et apporte plusieurs fonctionnalités utiles qui rendront votre travail avec les modèles de données INTERLIS dans QGIS encore plus efficace. L’une de ces fonctionnalités concerne la gestion des modèles INTERLIS avancés, qui pouvait être assez fastidieuse jusqu’à présent. Mais ce n’est plus le cas…

Du problème à la solution

Lorsqu’un modèle INTERLIS contient des sous-classes qui étendent les fonctionnalités d’une classe de base, celles-ci, y compris la classe de base, sont matérialisées dans la base de données physique… … et par conséquent, des couches sont créées dans QGIS. De plus, lorsque les classes ont les mêmes noms, il devient difficile de s’y retrouver. C’était assez fréquent.

QField 3.0 “Amazonia” is here – Feature-packed and super slick. – OPENGIS.ch

Tue, 24 Oct 2023 00:00:00 +0200

We’re so excited and proud of this latest QField version that we’ve opted for a major 3.0 version update. Get it now Shipped with many new features and built with the latest generation of Qt’s cross-platform framework, this new chapter marks an important milestone for the most powerful open-source field GIS solution.

Main highlights

Upon launching this new version of QField, users will be greeted by a revamped recent projects list featuring shiny map canvas thumbnails. While this is one of the most obvious UI improvements, countless interface tweaks and harmonization have occurred. From the refreshed dark theme to the further polishing of countless widgets, QField has never looked and felt better. The top search bar has a new functionality that allows users to look for features within the currently active vector layer by matching any of its attributes against a given search term. Users can also refine their searches by specifying a specific attribute. The new functionality can be triggered by typing the ‘f’ prefix in the search bar followed by a string or number to retrieve a list of matching features. When expanding it, a new list of functionalities appears to help users discover all of the tools available within the search bar. QField’s tracking has also received some love. A new erroneous distance safeguard setting has been added, which, when enabled, will dictate the tracker not to add a new vertex if the distance between it and the previously added vertex is greater than a user-specified value. This aims at preventing “spikes” of poor position readings during a tracking session. QField is now also capable of resuming a tracking session after being stopped. When resuming, tracking will reuse the last feature used when first starting, allowing sessions interrupted by battery loss or momentary pause to be continued on a single line or polygon geometry.

Analyzing and visualizing large-scale fire events using QGIS processing with ST-DBSCAN – OPENGIS.ch

Tue, 05 Sep 2023 00:00:00 +0200

A while back, one of our ninjas added a new algorithm in QGIS ’ processing toolbox named ST-DBSCAN Clustering, short for spatio temporal density-based spatial clustering of applications with noise. The algorithm regroups features falling within a user-defined maximum distance and time duration values. This post will walk you through one practical use for the algorithm: large-scale fire event analysis and visualization through remote-sensed fire detection. More specifically, we will be looking into one of the larger fire events which occurred in Canada’s Quebec province in June 2023.

Prise en charge de WMTS dans le plugin de localisation suisse de QGIS – OPENGIS.ch

Tue, 20 Jun 2023 00:00:00 +0200

Le plugin QGIS Swiss Locator facilite la vie de nombreux utilisateurs en Suisse en rendant accessibles les nombreuses géodonnées de swisstopo et opendata.swiss. Cela inclut un large éventail de couches de données, mais également des informations sur les objets et une recherche de noms de lieux. Grâce à un projet financé par le groupe d’utilisateurs suisse, OPENGIS.ch a pu ajouter des fonctionnalités supplémentaires à son plugin. Cette fois avec l’intégration de WMTS comme source de données. Mais quelle est la différence entre WMS et WMTS ? Tout d’abord, les similitudes : les deux protocoles – WMS et WMTS – conviennent au transfert d’images cartographiques d’un serveur vers un client. Cela signifie que ce ne sont pas des données brutes mais bien des données raster qui sont transmises qui conviennent donc pour des présentations dans le navigateur, dans le SIG de bureau ou pour une exportation PDF. La différence est dans le T. Le T signifie « tuilé ». Avec un WMS (sans tuilage), n’importe quelle image peut être demandée. Avec un WMTS, les données sont livrées dans une grille prédéfinie. Le principal avantage du WMTS réside dans la standardisation sur une grille. Cela permet à ces tuiles d’être temporairement stockées (c’est-à-dire mises en cache). Cela peut se faire sur le serveur, qui peut déjà précalculer toutes les tuiles et renvoyer un fichier directement sur demande sans avoir à recalculer une image. Cependant, il permet également la mise en cache côté client, ce qui signifie que le navigateur, ou dans le cas du localisateur suisse QGIS, peut simplement réutiliser chaque tuile sans recontacter le serveur. En conséquence, le temps de réaction peut être considérablement amélioré et vous pouvez travailler rapidement et avec fluidité au travers des applications. Alors pourquoi continuer à utiliser WMS ? Bien sûr, cela a aussi ses avantages. Le WMS peut fournir des images optimisées pour une requête précise. Par exemple, il peut placer de manière optimale toutes les étiquettes afin qu’elles ne soient pas coupées au bord de la carte. Ou combinez différentes couches interrogées avec des effets, les modes de fusion sont un moyen puissant de créer des cartes visuellement attrayantes. De plus, un WMS peut également fonctionner dans n’importe quelle résolution (DPI), ce qui signifie que les polices sont affichées dans une taille confortable sur chaque écran. Ou avec un export PDF. Un WMS présente également l’avantage qu’il n’y a pas de mise en cache. S’il y a une base de données derrière, l’état actuel des données est toujours fourni. Dans le cas de QGIS swiss locator, il s’agit souvent de charger des fonds de carte. chargez des orthophotos ou des cartes nationales pour vous orienter. Ou d’autres données, qui sont de nature plus statique. Dans ce scénario, les avantages du WMTS prennent tout leur sens. Et c’est pourquoi nous tenons à remercier le groupe d’utilisateurs QGIS Suisse au nom de tous les utilisateurs suisses de QGIS pour avoir rendu cette implémentation possible ! Le plugin Swiss Locator est le couteau suisse de QGIS. Y’a-t’il un outil qui vous manque et que vous apprécierez voir intégré? Faites-le nous savoir!

QField 2.8: Boosting field work through external sensors – OPENGIS.ch

Tue, 30 May 2023 00:00:00 +0200

The latest version of QField is out, featuring as its main new feature sensor handling alongside the usual round of user experience and stability improvements. We simply can’t wait to see the sensor uses you will come up with!

The main highlight: sensors

QField 2.8 ships with out-of-the-box handling of external sensor streams over TCP, UDP, and serial port. The functionality allows for data captured through instruments – such as geiger counter, decibel sensor, CO detector, etc. – to be visualized and manipulated within QField itself. Things get really interesting when sensor data is utilized as default values alongside positioning during the digitizing of features. You are always one tap away from adding a point locked onto your current position with spatially paired sensor readings saved as point attribute(s). Not wowed yet? Try pairing sensor readings with QField’s tracking capability! 😉 Head over QField’s documentation on this as well as QGIS’ section on sensor management to know more. The development of this feature involved the addition of a sensor framework in upstream QGIS which will be available by the end of this coming June as part of the 3.32 release. This is a great example of the synergy between QField and its big brother QGIS, whereas development of new functionality often benefits the broader QGIS community. Big thanks to Sevenson Environmental Services for sponsoring this exciting capability.

Capturing more while in the field with the new QField 2.7 – OPENGIS.ch

Tue, 04 Apr 2023 00:00:00 +0200

A brand new version of QField has been released, packed with features that will make you fall in love with this essential open source tool all over again with a focus on capturing more while you are in the field. QField 2.7 nicknamed “Heroic Hedgehog” also includes a number of worthy fixes making it a crucial update to get.

New recording capabilities

The highlight of QField 2.7 is the new audio and video recording capability straight from the feature form. In addition to preexisting still photo capture, this functionality allows for video motion and audio clips to be added as attachments to feature attributes. The audio recording capability can come in handy in the field when typing on a keyboard-less device can be challenging. Simply record an audio note of observations to process later. The experience wouldn’t be complete without audio and video playback support , which we took care of in this version too. Playback of such media content within the feature form gives an immediate feedback and saves time. For those interested in full screen immersion, simply click on the video frame to open the attached in your favorite media player. We also took the opportunity to implement audio and video playback on QGIS so people can easily consume the fruits of their labor in the field at their workstation. We would be remiss if we didn’t mention map canvas rotation functionality added in this version. This is a long-requested functionality which we are happy to have packed into QField now. Pro-tip: when positioning is enabled, double tapping on the lower-left positioning button will have the map canvas follow both the device’s current location as well as the compass orientation. Finally – some would argue « most importantly » 😉 – QField is now equipped with a beautiful dark theme which users can activate in the settings panel. By default on Android and iOS, QField will follow the system’s dark theme setting. In addition to the new color scheme, users can also adjust the user interface font size. Big thanks to Deutsches Archäologisches Institut who funded the majority of the new features in this release cycle. Their investment in making QField the perfect tool for them has benefited the community as a whole.

QField 2.6: perfecting high-accuracy positioning – OPENGIS.ch

Thu, 26 Jan 2023 00:00:00 +0100

It’s only been a few weeks into the new year, but we’ve got great news for you: a brand new QField 2.6 “Geeky Gecko ?” has been released with a focus on positioning improvements, including Bluetooth support for Windows. And with that, we are delighted to remove the ‘beta’ status from QField for Windows.

New positioning features

Let’s open with a bang: QField 2.6 now supports NMEA streaming from external GNSS devices over TCP, UDP, and serial ports, in addition to preexisting Bluetooth connectivity. This new functionality means that QField is now compatible with a much larger range of GNSS devices out there. These new receivers unlock NTRIP-driven centimetre accuracy for devices that use the Bluetooth connection to a manufacturer’s application to connect to NTRIP servers. In this scenario, QField could not initiate a Bluetooth connection since it was already taken. With the new TCP and UDP receivers – provided the manufacturer’s application offers NMEA streaming over either of those Internet protocols – QField can connect and consume high-accuracy positioning. The presence of a serial port receiver provides support for external GNSS devices using Bluetooth on Windows via the virtual serial port created by the operating system. The lack of Bluetooth support on Windows was a long-wanted enhancement from QField users on that platform and was the last blocker for the ‘beta’ status to go away. In addition, QField 2.6 allows users to pick from half a dozen metrics a value to attach to the measure (M) dimension of geometries being digitized when locked to the current position. This functionality is available to both users digitizing and the positioning tracker. The measurement values available as of 2.6 are timestamp, ground speed, bearing, horizontal accuracy and vertical accuracy, as well as PDOP, HDOP and VDOP values.

User defined field names in export from QGIS – OPENGIS.ch

Wed, 18 Jan 2023 00:00:00 +0100

Thanks to the sponsoring of the Swiss QGIS User Group, starting from QGIS 3.26 is it possible to override field names in the layer export dialog. Previous to that, QGIS would always export with the technical names from the database, whereas now it’s possible to override with the alias defined in QGIS or any custom name. One use for this in Switzerland — a highly polyglot country — is an export with translated names. This is done via an additional column « Export name ». For convenience we also added a tri-state checkbox to toggle export names to their alias defined in the layer configuration or back to the field name. If a name is changed by hand the checkbox shows a mixed state.

How to contribute to QField – OPENGIS.ch

Tue, 06 Dec 2022 00:00:00 +0100

QField is a community-driven open-source project. It is free to share, use and modify and it will stay like that. The very essence of a community is to help and support each other. And that’s where YOU come into play. To make it work we need your support! For those who don’t know much about the concept of open source projects, a bit of background. Investing in open-source projects is a technical and ethical decision for OPENGIS.ch. Open source is a technological advantage, as we receive input from many developers worldwide who are motivated to work out the best possible software. It prevents our customers from vendor lock-in and allows complete ownership and control of the developed software. And finally, not only financially independent businesses and people should benefit from professional software but also those who might not have the financial means to pay for features, and licences. You are not a developer, but you still like to use QField and support it? Good news. You don’t have to be a developer to use, contribute or recommend the app. There are plenty of things that need to be done to help QField to remain the powerful software it is right now and become even better. Here are a few suggestions on how you can give something back.

QGIS Relations, their Widgets and the Plugins of them – OPENGIS.ch

Tue, 29 Nov 2022 00:00:00 +0100

This blog post is about QGIS relations and how they are edited in the attribute form with widgets in general, as well as some plugins that override the relations editor widget to improve usability and solve specific use cases. The start is quite basic. If you are already a relation hero, thenjump directly to the plugins.

QGIS Relations in General

Let’s have a look at a simple example data model. We have four entities: Building, Apartment, Address and Owner. In UML it looks like this:

Model Baker INTERLIS Data Validator – OPENGIS.ch

Tue, 15 Nov 2022 00:00:00 +0100

The fully integrated Data Validator, which allows validating your data directly in QGIS against their INTERLIS model, exists for almost a year now. After lots of user feedback and some investments, it’s now shinier than ever. Time for an update and a little step-by-step guide.

Why is it so awesome?

Using the Model Baker Data Validator has two major advantages. First, you do not need to export your data before you validate them. Thanks to the --validate option, Model Baker can use ili2db to validate the data directly in the database. Second, you can interactively use the result list and zoom or pan to coordinates of validation issues in the QGIS map canvas or directly open or select the feature in question. So fixing the errors is much easier.

QField 2.5 is here, reaching new heights – OPENGIS.ch

Mon, 14 Nov 2022 00:00:00 +0100

Our ninjas have been so busy that less than a month after we released QField 2.4, we find ourselves with so many new features we simply can’t wait any longer to present to you the latest version of QField: 2.5 « Fancy Flamingo ?”. Exciting new features QField’s main new feature of this 2.5 release cycle is its brand new elevation profiling functionality which has been added to the measuring tool. Users are now able to dynamically build and analyze elevation profiles wherever they are – in the field or on their desktop – by simply drawing paths onto their maps and projects. This is a great example of QField’s capability at bringing the power of QGIS through a UI that keeps things simple and avoids being in your way until you need it. Oh and while we’re speaking of the measuring tool, check out the new azimuth measurement! This new version also brings multi-column support to feature forms. QField now respects the number of columns set by users in the attributes’ drag and drop designer while building and tweaking projects in QGIS. The implementation will take into account the screen availability and on narrow devices will revert to a one-column setup. Pro tip: try to change the background color of your individual groups to ease understanding of the overall feature form. Another highlight of this release is a brand new screen lock action that can be triggered through QField’s main menu found in the side dashboard or in the map canvas menu shown when long pressing on the map itself. Once activated, QField will become unresponsive to touch and mouse events while keeping the display turned on. When locked, QField also hides tool buttons which results in a more complete view of the map extent. Stability improvements As with every release, our ninjas have been spending time hunting nasty bugs and improving stability and QField 2.5 is no exception. In particular, the feature form should feel more reliable and even more polished.

Best of Swiss Enterprise App Award for QField – OPENGIS.ch

Thu, 03 Nov 2022 00:00:00 +0100

What a night it was. The « Best of Swiss Apps Awards » took place in Zurich yesterday, November 2, 2022. We were also nominated withQField. And in the enterprise category, the app was so convincing, that it was awarded the highest possible price. So it brought the award « Best of Swiss Enterprise App » home to Graubünden. And as cherry on the cake: QField was also nominated as finalist in the UX/UI category! We are extremely proud and happy about the received award. And even more when we look at the contendants that won in the other categories. We’re talking companies like SBB, Swiss Life, Switzerland Tourism and, yes, Rivella ?. You can check out all results at https://www.bestofswissapps.ch/bosa/hall-of-fame If you are interested in more details, we released a press release in German and in English. QField is an open source mobile app. The app is designed to use and edit geographically referenced data. In urban environments with 5G connectivity, but also with offline data. The mobile GIS app combines minimal design for simplicity with sophisticated technology for a versatile range of uses to bring data conveniently from the field to the offices. The app was started in 2011 and received a major rebuild in 2022. QField is mainly funded by customer feature requests, support contracts and sponsoring and is continuously improved an released for Android, iOS, Windows, MacOS and Linux. It offers a seamless QGIS integration and is GPS-centric, with offline functionality, synchronisation options and desktop configuration. QField is designed for fieldwork: simple, but uncompromising. The app is used internationally and is the first choice for mobile GIS projects. In the city, in the countryside and in the forest. Soon, QFieldCloud will also be launched. QFieldCloud is a cloud service integrated into QField that enables the remote provision and synchronisation of geodata and projects. And here some moments of the award night. It was a blast!

QField 2.4 is here, and it is ?icious – OPENGIS.ch

Thu, 13 Oct 2022 00:00:00 +0200

Yes, QField for QGIS, the leading fieldwork app, was released on the iOS App Store!

Get It now for Android, iOS, MacOS, Windows and Linux Good things take time (and sponsors), and we wanted our Apple users to enjoy the same solid and seamless experience as our Android users. So we took the time needed and ran beta testing of QField for multiple months. Thanks to all the community feedback and to the uncountable work hours put in by our development team, today we released QField on the iOS Appstore. Following the naming scheme for the 2.X series, we decided to name QField 2.4 Ecstatic Elk (Cervus Canadensis), honouring « the land of maple leaf ?? », the home country of Mathieu (QField lead UX designer) and origin of some recent funding.

How we build QField for many platforms – A look behind the curtain – OPENGIS.ch

Tue, 20 Sep 2022 00:00:00 +0200

In the past year,the build system behind QField has been ported tovcpkg, a modern C++ dependency management system. It has been a great success for QField and considerably helped to streamline efforts, improve the development experience and to guarantee an outstanding stability of the application. In this blog post we will look at the history of building QGIS based applications for mobile systems and how it has become what it is today. When Marco Bernasocchi (CEO of OPENGIS.ch and chair of QGIS.org) started working on QGIS for Android in Google Summer of Code a decade ago, the main job was to also build all QGIS dependencies for Android. This includes well-known libraries like proj and gdal and less-known ones like libxml2 or iconv. Each of them has its particularities and specific build flags. Working on this appears to be an endless iterative trial-and-error journey where you hope each day that eventually you will see the QGIS splash screen on your Android phone while all you see are endless lines of code and compiler errors. As we know nowadays QGIS for Android has eventually seen the sunlight and its achievements are still the base for QGIS-based mobile apps like QField. Sometime later we decided to modernize the build infrastructure into OSGeo4A a set of scripts where each dependency was built with a « recipe ». Modularized this way, it was easier to maintain, and general build code common for all libraries could be isolated. It was good enough to help drive QField for a couple of years, and a copy of it is still in use as the base for nowadaysQGIS builds for macOS. When we decided to make QField also available on other platforms like iOS, Windows and macOS we quickly realized that duplicating build chains scales really bad and maintaining this is an immense effort we wanted to avoid. There are a couple of existing C++ dependency management systems, none of which convinced us ultimately. Lucky for us a mail on the QGIS mailing list mentioned a new one called vcpkg which looked very promising. A couple of days later we had a build for Windows and later in the same year for macOS. With many dependencies already available in modern versions. Cheers. What’s left to do than just enable it for Android, and all our problems are suddenly solved? Alas, it’s not so easy. Cross-compiling is always a bit trickier. And so we started another journey to improve the situation. After a while, we had a working build chain based on vcpkg for Android in our R&D labs. Interestingly, this added a couple of features just because the community around vcpkg had already added them. For example using COG-based raster data via HTTP was suddenly working (for the record: thanks to the availability of curl which we never took care of adding ourselves in OSGeo4A). Soon after we also wanted to try building for iOS with vcpkg , which after a few attempts also was successful, and even managed to resolve some weird crashes and other issues we had experienced with the old buildchain. The main benefit was that we could upgrade the QGIS base libraries in one single place for every platform, in an isolated branch without playing the Jenga game on each upgrade. The only unfinished business we still had was that support for iOS and Android was still available only in our own vcpkg fork. So the last few weeks and months we have been working closely with upstream to bring building for Android and iOS up to the same level as desktop platforms. The relevant parts are now in a clean state. Advantages of this approach:

24th Contributors QGIS Meeting in Firenze 2022 – OPENGIS.ch

Thu, 08 Sep 2022 00:00:00 +0200

The international community of QGIS contributors got together in person from 18 to 22 August in parallel to OpenStreetMap State of The Map event and right before the FOSS4G. So there was a lot ofopen source geo power concentrated in the beautiful city of Florence in those days. It was my first participation and all I knew was that it’s supposed to be an unconference. This means, there is no strict schedule but space and opportunity for everyone to present their work or team up to discuss and hack on specific tasks to bring the QGIS project to the next level.

Writing a feature-based processing algorithm at the example of M-value interpolation – OPENGIS.ch

Tue, 30 Aug 2022 00:00:00 +0200

Amongst all the processing algorithms already available in QGIS, sometimes the one thing you need is missing. This happened not a long time ago, when we were asked to find a way to continuously visualise traffic on the Swiss motorway network (polylines) using frequently measured traffic volumes from discrete measurement stations (points) alongside the motorways. In order to keep working with the existing polylines, and be able to attribute more than one value of traffic to each feature, we chose to work with the M-values. M-values are a per-vertex attribute like X, Y or Z coordinates. They contain a measure value, which typically represents time or distance. But they can hold any numeric value. In our example, traffic measurement values are provided on a separate point layer and should be attributed to the M-value of the nearest vertex of the motorway polylines. Of course, the motorway features should be of type LineStringM in order to hold an M-value. We then should interpolate the M-values for each feature over all vertices in order to get continuous values along the line (i.e. a value on every vertex). This last part is not yet existing as a processing algorithm in QGIS. This article describes how to write a feature-based processing algorithm based on the example of M-value interpolation along LineStrings.

A New Trick up QField’s Sleeve: Animated Maps – OPENGIS.ch

Tue, 16 Aug 2022 00:00:00 +0200

Starting with QField 2.2, users can fully rely on animation capabilities that have made their way into QGIS during its last development cycle. This can be a powerful mean to highlight key elements on a map that require special user attention. The example below demonstrates a scenario where animated raster markers are used to highlight active fires within the visible map extent. Notice how the subtle fire animation helps draw viewers’ eyes to those important markers. Animated raster markers is a new symbol layer type in QGIS 3.26 that was developed by Nyall Dawson. Supported image formats include GIF, WEBP, and APNG. The second example below showcases more advanced animated symbology which relies on expressions to animate several symbol properties such as marker size, border width, and color opacity. While more complex than simply adding a GIF marker, the results achieved with data-defined properties animation can be very appealing and integrate perfectly with any type of project. You’ll quickly notice how smooth the animation runs. That is thanks to OPENGIS.ch’s own ninjas having spent time improving the map canvas element’s handling of layers constantly refreshing. This includes automatic skipping of frames on older devices so the app remains responsive. Oh, we couldn’t help ourselves but take the opportunity to demonstrate how nice the QField feature form layout is these days in the video above ? To know more about other new features in QField 2.2, go and read the release page. Happy field mapping to all! The lovely animal markers used in the zoo example above were made by Serbian artistArsenije Vujovic.

High Efficiency with Buffered Transactional Editing in QGIS – OPENGIS.ch

Tue, 26 Jul 2022 00:00:00 +0200

Tired of start/stop editing for every single layer in your project with mixed data sources?
Starting from version 3.26, QGIS has a new transaction mode called « Buffered Transaction Groups ». Within this mode, all layers which are not read-only are put in one « transaction group » and handled together when the actions « Toggle Editing » or « Save Layer Edits » are activated. It doesn’t matter if the layers come from different providers like GeoPackage, PostgreSQL or Shapefile. Edits are buffered locally and saved within one single transaction on all layers per provider. With this, you can store all edited layers with a single click. And in comparison to the well-known « Automatic Transaction Groups » mode you have better performance during editing and fewer problems with locking of the database when multiple users edit the same table in parallel. To try it out; go to Project - > Properties -> Data Sources -> Transaction mode Enjoy and let us know what you think!

QField Users Sit Down, We Need to Talk About Storage Access on Android – OPENGIS.ch

Sat, 05 Mar 2022 00:00:00 +0100

TLDR: Since November 2021, Google has enforced new storage access limitations for apps published on its Play store which prohibits direct storage access on Android 11 and above forcing QField to adapt and rely on importing projects and datasets to access those. If you are a QField beta user on Android 11 and above, you might have noticed a significant change in the way the app is handling storage in the latest set of betas released in early February of 2022. This blog post will go over the changes, explain why those had to be made (looking at you, Google), how to work in this new paradigm, and showcase some new benefits from the hard work done by OPENGIS.ch’s geoninjas.

By publishing QField as an open-source app, OPENGIS.ch allows companies, organisations and even countries without the necessary financial means to have the opportunity to benefit from this important data collection app. And it is being used: Over half a million downloads have already been achieved. Now, since the volcanic eruption in Tonga on 15 January 2022, the app of the small Laax-based company is playing a not-unimportant role in disaster response planning. We’ve only been around for seven years. We could almost pass for a start-up. But OPENGIS.ch is already a household name when it comes to field data collection. OPENGIS.ch makes its field mapping tool QField available without restrictions (i.e. open-source) so that companies or even nations can collect their geographical data. In this way, data is brought from the field to the office and provides important insights for future decisions. This was also the case for Tonga’s volcanic eruption. There, in December 2021, many relevant agricultural datasets were captured with « QField » and « QFieldCloud ». This currently helps the Ministry of Agriculture, Food, Forests, and Fisheries to analyse the damage after the volcanic eruption and the subsequent tsunami and plan the response.

QField 1.7 Rockies hits the stage – OPENGIS.ch

Tue, 20 Oct 2020 00:00:00 +0200

Be ready for the cold weather with a smooth coordinate search, filters in the value relation widget, fancy new QML and HTML widgets, enhanced geometry editing functionalities and an expandable legend. Right when Autumn starts, QField 1.7 Rockies hits the stage. As usual get it now on the play store or on github! The days are getting shorter and the wind blows colder. It’s always good to be in a good company outside while getting your mapping work done. QField will be your reliable companion. We know, QField 1.6 Qinling has only been out two months and with its amount of new features and stability improvements, it would have deserved a longer primetime. But we just couldn’t withhold you all the new great stuff we’ve been building lately. So let’s welcome QField 1.7 Rockies. And yes, we mean THE Rockies, where QField is looking for plenty of new buddies. Let’s have a look.

QField 1.6 is out! – OPENGIS.ch

Tue, 18 Aug 2020 00:00:00 +0200

Editing multiple features at the same time, support for stylus pens, dynamic configuration of image names and much more.
QField 1.6 Qinling 秦岭 comes packed with awesome new features and an improved user experience. We have been very busy over the last few months working on a new and shiny QField release. We have added many new features that increase efficiency on the field or allow for new workflows. In parallel, we have also been working on ironing out a series of issues and improving the overall user experience to make the app as pleasurable to use as possible. The result is QField 1.6 which has been published now. Enough of the highlevel talking, let’s see what has been done.

Generate DXF on QGIS server – OPENGIS.ch

Wed, 24 Jun 2020 00:00:00 +0200

Everyone knows QGIS is on the desktop and mobile devices. Many know QGIS is on the web with QGIS server through OGC services. Some know QGIS server has its own extension to generate PDFs. But did you know that QGIS server can also produce DXF files?

DXF

DXF files are mainly used for interchanging CAD drawings, vector geometries with styles and attributes. With a couple of compromises, these files can be imported and exported to and from QGIS. Due to their heavy use of CAD software, architects work a lot with DXF files. For example, for the Swiss Cadastral Survey (Amtliche Vermessung, Mensuration Officielle) there is a standard with the name GEOBAU-DXF that defines layer names and structure of this file. Architects often request this format from cantonal government agencies when planning construction work. In the canton of Schaffhausen, there are over 100 downloads per month and it’s by far the most demanded format. These files were produced semi-automatically through a separate application and the customers got the data by mail with a link to a zip file. The time between order and delivery was about 20 minutes. With the renewal of the cantonal SDI, including QGIS server for handling OGC services, the situation changed and an update to this process was required.

Offline WMS – Benchmarking raster formats for QField – OPENGIS.ch

Tue, 09 Jun 2020 00:00:00 +0200

What are we looking for?

We would like to use WMS offline on QField. For that, we need to figure out what is the best way to get a raster from a WMS and which format is the most efficient (size and performance). In this post we’ll show you is how to generate the ideal raster file from a WMS and the results of our efficiency tests for the the different raster formats.

Amélioration du gestionnaire d’extensions – OPENGIS.ch

Tue, 14 Apr 2020 00:00:00 +0200

Lors de l’assemblée générale de 2020, le groupe d’utilisateurs QGIS Suisse a accepté la proposition d’amélioration du gestionnaire d’extensions. Ainsi, dans la version 3.14, il sera possible d’installer au choix la version stable ou expérimentale d’un plugin. Cette fonctionnalité permettra d’améliorer la collaboration entre les développeurs et les utilisateurs d’un plugin. Les utilisateurs pourront facilement basculer entre la version d’un plugin utilisé en production et une version expérimentale pour tester les fonctionnalités à venir. Jusque là, il était nécessaire soit de configurer un dépôt d’extension dédié, soit d’installer les versions expérimentales manuellement à partir d’un fichier zip. Pour tester cette fonctionnalité, assurez-vous d’avoir activé l’option « afficher les extensions expérimentales » et d’utiliser une version de développement (Nightly build) de QGIS récente. Nous remercions chaleureusement le groupe d’utilisateurs QGIS Suisse d’avoir financé cette amélioration !

Tue, 03 Mar 2020 00:00:00 +0100

What a year’s start! After a very packed December publishing all the QGIS on the road videos and quietly releasing QField 1.3 – Ben Nevis we could have gone and relaxed over the holidays. But since we love QField so much we immediately started working on the next iteration. Now, after an intensive testing period, we are proud to announce the release of QField 1.4 – Olavtoppen. Olavtoppen!? yes, the highest point of Bouvet Island, the remotest island on Earth. And sure enough, QField would follow you there! As usual, get it on play store or download it from GitHub.

First QField user day – OPENGIS.ch

Thu, 27 Feb 2020 00:00:00 +0100

A huge success

At the end of 2019, we organised the first QField user day in Bern. Around 40 participants from Switzerland and neighbouring countries joined the packed event with use case presentations by various power users of QField.

Fantastic use-case presentations

After a brief introduction by Matthias, Samuel Wechsler from the Swiss Ornithological Institute showed how they make their teams fly with QField to be more effective in protecting the Swiss bird fauna and its habitat. Next on the podium was one of the earliest QField pioneers, Daniel Gnerre from the city of Vevey telling the audience how the city thoroughly uses QField to collect and update data on just about anything and how they integrated QField in their geospatial infrastructure. After a short break, Philipp Eigenmann showed us how he uses QField to manage the forest he and his team are responsible for. Finally, Samuel Oester and Till Weber from Oester Messtechnik presented Gasbusters – Chasing gas with QField explaining how they used QField in over 200 soil gas leaks campaigns measuring over 39’000 points to be then visualised on maps and with Grafana.

Thu, 19 Dec 2019 00:00:00 +0100

The Last Bee

After expanding into the mountains and showing us how she uses spatial bookmarks and live layers to manage her hives without leaving home, Maya also started a new business: with the help of the QGIS’ print layout manager, QGIS server and the Lizmap Web Client, Maya got her infrastructure ready for tourism. In case you missed it, watch Episode V: The Web Strikes Back or even better, follow us on Twitter and LinkedIn for all updates. Terrible news, a killer bee swarm escaped from a laboratory in northern Italy. Maya is desperate, if the killer bee reach her hives, it’s all gone. Maybe the weather could help Maya so she modelling the speed of travel of the killer bees and animates her analysis to see if her bees are likely to survive…

QGIS on the Road: Episode IV – A New Hope – OPENGIS.ch

Thu, 12 Dec 2019 00:00:00 +0100

A new hope

In the last episode, Maya minimized the damage the destructor made to her bees, using complex forms and widgets , the advanced functionalities of the attribute table ,live layers and even QField for mobile data collection. In case you missed it, watch Episode III: Attack of the Destructor or even better, follow us on Twitter and LinkedIn for all updates. Maya is coming back with a lot of new ideas, demanding more QGIS power. Since she has received plenty of great feedback on honey from hives located at certain spots, she wants to have full overview over the whole area now. First, she uses relations to link information on different layers, then she creates animated charts on feature forms with the QML widget and – to cover the entire area – she uses the advanced digitizing tool to create precise geometries using angles and distances based on a paper sketch.

QGIS on the Road: Episode III – Attack of the Destructor – OPENGIS.ch

Tue, 10 Dec 2019 00:00:00 +0100

Attack of the Destructor

In the last episode, Maya started to populate many beehives around her home. She has visualized and labeled them to have concise information and an easily understandable map representation of her honey production. In case you missed it, watch Episode II: The Rise of the Hives or even better, follow us on Twitter and LinkedIn for all updates. After Maya realizes that many of her beehives have been infected by severe diseases she needs to act quickly to get an overview of the situation. She grabs some friends and tablets and launches QField to map the situation. After assessing the results with advanced configuration of the attribute table she is ready to choose the right measures and do a precise intervention. And of course, this precise intervention is accompanied with a visualization that is on fire.

Plugin for tracking QGIS project files in git – OPENGIS.ch

Tue, 09 Apr 2019 00:00:00 +0200

We often have QGIS project files that are part of a customer project. To be able to manage versions of these project files or have multiple people working on it, they are managed inside a git repository. This is however not easy, because with every save of a project file, thousands of lines change, even if the real change is minimal. Like a change of a layer name. This blows up the git repository for no reason. And worse: it makes it impossible to review changes, because the signal to noise ratio is horrible. OPENGIS.ch has just released a shiny jewel to make your life easier. The Trackable QGIS Projects plugin will automatically rewrite the saved project into a much more stable format. Just download the plugin, install it and you are done. No user interface available, no configuration needed.

Let’s see what makes QField probably*We might be biased, but we do believe it the best mobile GIS in the world.

GeoBeer #26 in Bern hosted by OPENGIS.ch – OPENGIS.ch

Mon, 25 Mar 2019 00:00:00 +0100

Last Thursday around half past six in the evening. Striking many Geo-scientist found the way to the Spitalgasse in Bern. The reason was the 26th GeoBeer event taking place at ImpactHub.
GeoBeer is a quarterly meeting of people interested in geography, GIS, cartography and the latest technologies. It’s hosted every time by someone else. This time by us, OPENGIS.ch. Right after the arriving, the organizers of GeoBeer Switzerland showed us some funny statistics about the GeoBeer participants since the very first GeoBeer event six years ago.
Marco Bernasocchi then welcomed everyone and introduced our company. We had three speakers this time. Marcus Hudritsch of the Berner Fachhochschule started by presenting the implementation of the visualization of historical buildings, that do not exist anymore in reality. But still, do in virtual reality… No sorry, it’s augmented reality. Marcus Hundritsch explained to us clearly the difference between AR and VR and presented some projects they made. Pascal Bourquin changed perspective completely by telling us about his project (La Vie en Jaune) to cover all the hiking trails of Switzerland – he logs every trail done on a map with photographs. The final speaker was Daniele Viganò from the Global Earthquake Model Foundation talking about their challenges of calculating a global model of earthquake hazard, risk and exposure.

QField RC5 – Last call for testing – OPENGIS.ch

Thu, 14 Mar 2019 00:00:00 +0100

We are really happy to announce the fifth and (hopefully) last 1.0 release candidate in QField’s history! This means that QField 1.0 is closer than ever. Get it while it’s hot on the Playstore (https://qfield.org/get) or on GitHub Thanks to all the feedback by the fantastic community we were able to fix plenty of bugs, address performance issues and even add some super cool new features. Among the new features, the most important is the flashy new file selector with favorite directories (long press on a folder to add it to the favorites and longpress on the favorites list to remove it) and an automatic list of the last three opened projects that will save you heaps of time while looking for your projects. Another lifesaver is the newly added support for pasting text from the clipboard in the search bar. Finally, we added a smart and unobtrusive « rate this app » dialog to make it easier for you to give QField the ★★★★★ you always wanted to give it 🙂 List of improvements since RC3

You gave us feedback – we give you QField 1.0 RC3 – OPENGIS.ch

Thu, 31 Jan 2019 00:00:00 +0100

We are really happy to announce the release a new great milestone in QField’s history, QField 1.0 Release Candidate 3! (Yes, you might have got a glimpse of the broken RC2 if you where very attentive) Thanks to the great feedback we received since releasing RC1 we were able to fix plenty of issues and add some more goodies. We would like to invite everybody to install this Release Candidate and help us test it as much as possible so that we can iron out as many bugs as possible before the final release of QField 1.0. List of fixes since RC1:
• fixed bad synchronization / geopackage files not written) (PR #455)
• fix glitches in portrait mode (PR #423 and #439)
• fix highlighting of points (search and feature selection) (PR #443)
• fix GPS info window overlapping search icon (PR #438)
• redesign of scale bar (PR #438)
• fix crash in feature form (with invalid relations) (PR #440)
• fix date/time field editing (PR #421 and #458)
• fix project not loading the correct map theme (fix #459)
• fix QGS or QGZ does not exist (PR #453) Unfortunately, due to necessary updates in the SDK we target, we had to drop support for Android 4.4. The minimum Android requirement as of this RC is Android 5.0 (SDK version 21). In case playstore does not suggest an update to QField Lucendro 0.11.90, the last working version for Android 4.4, we suggest all Android 4.4 users to uninstall QField 1.0 RC 1 (which was broken on android 4.4) and reinstall QField from the store. This way you should get If you don’t use play store, you can find all QField releases under https://qfield.org/releases You can easily install QField using the playstore (https://qfield.org/get), find out more on the documentation site (https://qfield.org) and report problems to our issues tracking system (https://qfield.org/issues) QField, like QGIS, is an open source project.

Visualize Postgres JSON data in QML widgets – OPENGIS.ch

Tue, 13 Nov 2018 00:00:00 +0100

As promised some time ago in «The new QML widgets in QGIS – When widgets get unbridled » we still owe you some fancy unicorns, but first let’s have a look at another nice feature that has been introduced in QGIS 3.4 LTR, the reading of PostgreSQL JSON and JSONB types.
With JSON you have a lot of possibilities for storing unstructured data. In our case, it’s mainly interesting when the data are stored as an array or a JSON object. Let’s have a look at two examples.

The new QML widgets in QGIS – When widgets get unbridled – OPENGIS.ch

Tue, 06 Nov 2018 00:00:00 +0100

Individuality is the definition of freedom. And freedom is the fundamental requirement of man’s mind. QGIS possibly cannot give you all the freedom you require in life. But at least a lot of freedom in how you manage your work. QGIS 3.4.0 LTR was released last week and it comes loaded with features supporting big freedom in the configuration of your projects. Let’s focus on the QML Widget. QML is the smart casual look of widgets. With the help of some simple code, you will be able to visualize your data in the attribute form like never before. You can display beautiful charts, complex JSON data, and fancy colored unicorns.

QGIS speaks a lot of languages – OPENGIS.ch

Tue, 11 Sep 2018 00:00:00 +0200

QGIS is a real cosmopolitan. Born in Alaska sixteen years ago, it has spread all over the world since. Thanks to its open source mentality, it finds not only in economically strong countries big usergroups. No question, that beside all the developers, there is a bunch of brave translators giving everything to make and keep QGIS multilingual. It’s translated in over forty languages – even to Mandarin Chinese and Esperanto. Not only the application, but also its plugins.
And since the feature-loaded long term release 3.4.0 even the QGS-Projects themselves. Thanks to the friendly support ofQGIS Usergroup Switzerland and the QGEP Project.

Using Threads in PyQGIS3 – OPENGIS.ch

Fri, 22 Jun 2018 00:00:00 +0200

While porting a plugin to QGIS3 I decided to also move all it’s threading infrastructure to QgsTasks. Here three possible variants to implement this.
the first uses the static method QgsTask.fromFunction and is simpler to use. A great quick solution. If you want need control you can look at the second solution that subclasses QgsTask. In this solution I also show how to create subtasks with interdependencies. The third variant, illustrates how to run a processing algorithm in a separate thread.
One thing to be very careful about is never to create widgets or alter gui in a task. This is a strict Qt guideline – gui must never be altered outside of the main thread. So your progress dialog must operate on the main thread, connecting to the progress report signals from the task which operates in the background thread. This also applies to « print » statements — these aren’t safe to use from a background thread in QGIS and can cause random crashes. Use the thread safe QgsMessageLog.logMessage() approach instead. Actually you should forget print and always use QgsMessageLog.

How to filter features in QGIS using the graphical processing modeler – OPENGIS.ch

Mon, 28 May 2018 00:00:00 +0200

This article describes a new algorithm for the processing modeler called feature filter algorithm. If you are already familiar with ETL concepts and the graphical modeler, you can directly jump to the section the feature filter algorithm.

Building workflows for repetitive tasks

When building workflows for simple or complex geodata infrastructures, one of the most common tasks one encounters is to extract some of the features and copy them to another destination. Sometimes they need to be modified and a few attributes calculated or deleted, maybe even the geometry needs to be adjusted or in some fancy situations one even wants to generate a couple of objects from one input object. This process is often called ETL (Extract, Transform, Load) and it is something that is worth mastering as a GIS expert.
Let’s imagine a situation where we sent a field worker out to collect information about public infrastructure, equipped with a brand-new tablet and the latest and greatest version of QField. To make his task super easy, we prepare one single layer for him with an attribute type which can be set to Bus Station, Car Parking or Train Station. Now back in the office we want to integrate this back into our spatially enabled database which has been designed with 3 target tables.

Porting QGIS plugins to API v3 – Strategy and tools – OPENGIS.ch

Fri, 13 Apr 2018 00:00:00 +0200

The Release of QGIS 3.0 was a great success and with the first LTR (3.4) scheduled for release this fall, it is now the perfect time to port your plugins to the new API.
QGIS 3.0 is the first major release since September 2013 when QGIS 2.0 was released. During the release cycles of all 2.x releases, the QGIS Python API remained stable. This means that a plugin or script meant to be used in QGIS 2.0 is still working in QGIS 2.18.
The need for a new major release was principally motivated by the update to newer core libraries such as Qt 5 and Python 3. But it also offered a unique opportunity to the development team to tackle long-standing issues and limitations which could not be fixed during the 2.x life cycle. Inevitably, this introduced multiple backward incompatibilities making scripts and plugins unusable in QGIS 3.
In this post, I’d like to share some notes from my latest ports. Obviously, if you need professional help for porting your plugins, don’t hesitate to contact us.

PostgreSQL back end solution for quality assurance and data archive – OPENGIS.ch

Mon, 08 Jan 2018 00:00:00 +0100

Did you know that the possibilities to make a full QGIS back end solution for quality assurance and archiving in PostgreSQL are immense? SQL has it’s well known limitations, but with a little bit creativity you can make quite nice solutions just using triggers and rules. In this post I’ll explain what we did lately based on a project with a customer. He needed to assure the consistency of data but still give his employees the possibility of a fast feeding of the data collected on the field to the database. Another request was to keep every status of the data with the information about the changes (archiving).
It’s always the question, where to put the logical part of the solution. QGIS is quite powerful with constraints, but the undeniable advantage of a back end solution is, that you can use any front end – no matter what configuration you have on QGIS or what Feature Manipulation Engine (FME) you use – without influencing the guarantee of data validity.

Interlis translation – OPENGIS.ch

Fri, 01 Dec 2017 00:00:00 +0100

Lately, I have been confronted with the need of translating Interlis files (from French to German) to use queries originally developed for German data. I decided to create an automated convertor for Interlis (version 1) Transfer Format files (.ITF) based on the existing cadastral data model from the Swiss confederation (DM01AVCH).
The ILI model file conversion has been achieved manually once. This was quite simple since the used model is an extension with little to no difference with respect to the confederation model which already exists in several languages.
Next was to automate the conversion of the ITF files.
A program developed by Swisstopo called DM01AVCH_Translator existed to translate confederation model’s ITF files. Originally developed in 2008, the solution is sadly no longer maintained by Swisstopo and was available on Windows only. Moreover it can’t be completely automated since some interaction is required in the GUI and some tweaks in the output file are needed.
So I decided to develop a dedicated and fully automated solution which I’d like to share since it is easily adaptable to new scenarios and hopefully can avoid troubles to those who are playing with Interlis files!
You can find this utility, written in Python, called ITF_Translator on https://github.com/opengisch/ITF_Translator

Best practices for writing Python QGIS Expression Functions – OPENGIS.ch

Wed, 10 May 2017 00:00:00 +0200

Recently there have been some questions and discussions about python based expression functions and how parameters like usesGeometry need to be used. So I thought I’d quickly write down how this works.

There is some intelligence

If the geometry or a column is passed in as a parameter you do not need to request it manually, you can even specify explicitly that you do not require the geometry or a column here.

QGIS Expressions Engine: Performance boost – OPENGIS.ch

Tue, 02 May 2017 00:00:00 +0200

Expressions in QGIS are more and more widely used for all kinds of purposes. For example the recently introduced geometry generators allow drawing awesome effects with modified feature geometries on the fly. The last days at the QGIS developer meeting 2017, I spent some time looking into and improving the performance for expressions. This was something that was on my todo list for a while but I never got around to working on it. Short story:

QGIS2 compatibility plugin – OPENGIS.ch

Mon, 19 Sep 2016 00:00:00 +0200

Lately I’ve been spending time porting a bigger plugin from QGIS 2.8 to 3 while maintaining 2.8 compatibility.
You can find it at https://github.com/opengisch/qgis2compat/
and https://plugins.qgis.org/plugins/qgis2compat/
One code to rule them all.
My target was to have to edit the source code as little as possible to simulate a lazy or busy coder that has to upgrade his/her plugins.
Lots of work has already gone into 2.14 to support PyQt 4 and 5 with the same code (Kudos to jef-n and mkuhn).

Updating PyQt signals that use lambda in QGIS with 2to3 – OPENGIS.ch

Sun, 11 Sep 2016 00:00:00 +0200

Just for the sake of documenting things, when running qgis 2to3 on a plugin I encountered a tricky situation regarding signals.

MYQGISDIR/scripts/2to3 -f signals -w my/plugin/path

The original code:

extra_arg = "my test argument"
QObject.connect(
 action,
 SIGNAL( "triggered()"),
 lambda extra_arg=my_arg: show_extra_arg(extra_arg))
def do_load_project(extra_arg):
 print extra_arg # "my test argument"

The generated code:

extra_arg = "test_arg"
action.triggered.connect(
 lambda extra_arg=my_arg: show_extra_arg(extra_arg))
def do_load_project(extra_arg):
 print extra_arg # False

so in do_load_project we get False instead of « my test argument » , why?
well due to a subtle difference in the generated code. in the original code we had the signature triggered() which has no arguments, so in our lambda extra_arg gets passed my_arg.
in the generated code, triggered actually has an optional param checked [1] which if emitted gets passed to extra_arg causing the problem.
The correct code (note the additional argument in the lambda definition)

Using threads in QGIS python plugins – OPENGIS.ch

Wed, 07 Sep 2016 00:00:00 +0200

I really wanted to write this post since a long time but things got in the way, and now an email finally triggered me.
As part of a consultancy I got to work with threads in a python plugin for QGIS. Since it was a pretty tedious process, I decided to write the whole thing fairly generic so that it could be used easily by others.
Before using this, please note that there are ongoing efforts to get something like this directly in QGIS 3.
The code below (or maybe a more recent version – the one posted here is 1da300f from May 6, 2015) can be found on github
The usage is pretty self explanatory but it goes like this. You create your worker class that inherits from AbstractWorker and implement the work method:

QGIS: Qt5 and Python3 migration, current state – OPENGIS.ch

Wed, 04 May 2016 00:00:00 +0200

Behind the scenes a lot has happened to get ready for Qt5 and Python3. On the same codebase that is becoming the next release QGIS 2.16. This is really a great thing since we can focus work on a single master branch and I’m very happy that we got so far with this approach already.

Testing

At OPENGIS.ch we have put a huge effort into getting the Travis CI test infrastructure to test our code with Qt5 and Python 3. This gives us confidence that we don’t have regressions introduced once we declare Qt5 and Python 3 to be default. At the time of writing we have 177 tests passing on Qt5/Python3 vs 211 tests on Qt4/Python2. Most of the missing tests are caused by a single issue (PyQt5 and NULL, see below).

Prepare your plugins for QGIS 3 – OPENGIS.ch

Wed, 23 Mar 2016 00:00:00 +0100

QGIS 3 is not yet there and there is still plenty of time to prepare and migrate.
But I thought I would give some advice about things that you can keep in mind while working on your plugins to make your life easier when you will have to actually do the migration. It’s mostly about making your code prepared for Python 3 and PyQt5.

Do not use star imports

Don’t do

Increasing the stability of processing algorithms – OPENGIS.ch

Thu, 04 Feb 2016 00:00:00 +0100

Processing just got a new testing framework to improve the long-term stability of this important plugin. And you can help to improve it, even if you are not a software developer!
This is yet another piece in our never-stopping crusade to improve the stability and quality of the best desktop GIS on the market.

Processing

You probably know processing. If you don’t: processing is the number one plugin to enable after every QGIS installation. It offers a very wide variety of geo-algorithms from generic one to very task-specific tools and allows building models and to completely automate workflows this way.
Processing is being improved consistently and gets better with every release. But like always in software development, there is a risk, that an improvement can have undesired side-effects which break previously working parts of an application.

Geometry generator symbology – OPENGIS.ch

Thu, 10 Dec 2015 00:00:00 +0100

December traditionally is an amazing time since the weather is usually quite forgiving to long working hours.
Therefore the first parts of our recent crowdfunding project for 2.5D rendering have been merged into QGIS master and will be shipped with QGIS 2.14.
It’s something of the sort of development that we really, really, really like here at OPENGIS.ch: an implementation that adds enormous flexibility and enables the user to use QGIS in ways that we never thought of.
Say hello to geometry generators.
Geometry generators allow to use expression syntax to generate a geometry on the fly during the rendering process. The resulting geometry does not have to match with the original geometry type and you can add several differently modified symbol layers on top of each other.

QField Documentation – OPENGIS.ch

Thu, 10 Dec 2015 00:00:00 +0100

After getting QField up and running in Android 5, we felt it was time to start documenting how QField works, we started documenting how to install and use QField. We also added a section on how to handle your data to get them on QField. It is all pretty basic, but it dose give some hints.
You can find the documentation here: https://qfield.org/docs/
As QField’s source code the docs are opensourced (on github) and we look forward for your help in documenting and translating.
Thanks a lot

Passing android Intents to Qt – OPENGIS.ch

Thu, 03 Dec 2015 00:00:00 +0100

Working on QField I had the necessity of passing values from the QtActivity.java to the Qt cpp world, here how I did it using an Intent that is sent to the QtActivity (the one you should not edit that comes with Qt). For much more information see this post series.
hopefully this will be helpful to someone.

private void startQtActivity() {
	String dotqgis2_dir = "Test dotqgis2_dir";
	String share_dir = "Test share_dir";
	// forward to startQtActivity and finish QFieldActivity
	Intent intent = new Intent();
	intent.setClass(QFieldActivity.this, QtActivity.class);
	intent.putExtra("DOTQGIS2_DIR", dotqgis2_dir);
 intent.putExtra("SHARE_DIR", share_dir);
	startActivity(intent);
	finish();
}

#include <QAndroidJniObject>
#include <QtAndroid>
#include <QDebug>
#ifdef Q_OS_ANDROID
QString getExtra(QAndroidJniObject extras, QString extra){
 if(extras.isValid()){
 QAndroidJniObject extra_jni = QAndroidJniObject::fromString(extra);
 extra_jni = extras.callObjectMethod("getString", "(Ljava/lang/String;)Ljava/lang/String;", extra_jni.object<jstring>());
 if (extra_jni.isValid()){
 extra = extra_jni.toString();
 qDebug() << extra;
 return extra;
 }
 }
 return "";
}
void getIntentExtras(QStringList intentExtras)
{
 QAndroidJniObject activity = QtAndroid::androidActivity();
 if (activity.isValid()) {
 qDebug() << "activity";
 QAndroidJniObject intent = activity.callObjectMethod("getIntent", "()Landroid/content/Intent;");
 if (intent.isValid()) {
 qDebug() << "intent: " << intent.toString();
 QAndroidJniObject extras = intent.callObjectMethod("getExtras", "()Landroid/os/Bundle;");
 qDebug() << "extras: " << extras.toString();
 QString extra;
 for (int i = 0; i < intentExtras.size(); ++i){
 extra = intentExtras.at(i).toLocal8Bit().constData();
 getExtra(extras, extra);
 }
 }
 }
}
QStringList intentExtras;
intentExtras << "DOTQGIS2_DIR" << "SHARE_DIR";
getIntentExtras(intentExtras);
#endif

This is the first version of the cpp code that I wrote, just for reference. The above code is much cleaner

QField for Android 5 – OPENGIS.ch

Tue, 01 Dec 2015 00:00:00 +0100

QField app QField Karma edition app It’s done, finally we managed to get rid of Ministro so that we finally can say, QField runs on any android from 4.0.3 (ICS). This makes as of today (according to google) 96% of the android installations worldwide. Eventually we want to settle to 4.3 (JB) as minimum to allow us using certain features and avoiding one known issue, but for now it would mean cutting of another 25% of the users.
So as of today it is: 4.0.3 (Ice cream sandwich API 15) is the required minimal Android version to run QField and Android 4.3 (Jelly Bean API 18) is the suggested minimal version.
We tested with 4.4, 5.0.1 and 5.1 but we haven’t had the chance to get our hands on an Android 6 so if you can, let us know how it works.
But adding support for android 5 isn’t the only great news, during the process we also:

QGIS Crowdfunding: 2.5D Rendering – OPENGIS.ch

Mon, 02 Nov 2015 00:00:00 +0100

QGIS has a great variety of rendering possibilities from categorization to data defined settings which allows to make awesome cartographic products. It also features some extensions like qgis2threejs and globe that make it possible to explore the third dimension. While these extensions are great tools they have their limitations like they do not fully integrate with the styling system or cannot be used in print composers.

Mockup of a possible rendering result with a combination of classify and 2.5D effect This project aims to improve the internal possibilities of QGIS to give an oblique view 3D effect based on a height attribute and an angle while fully preserving all the possibilities which the QGIS styling offers. But it doesn’t stop there, the whole rendering is built in a modular way so you can use all of its parts for countless other possibilities.
Funds are already available for a major part of this project thanks toADUGA and the Regional Council of Picardy. For the missing pieces we would like to ask the community to help us to create the required extensions to include these amazing new functionalities into QGIS.

SpaceMouse in Ubuntu 15.04 – OPENGIS.ch

Wed, 14 Oct 2015 00:00:00 +0200

While preparing some 3D scenes for an exibition I discovered the SpaceMouse by 3dconnexion. A neat device we plan on installing in front of a projected globe.
To get it to run in Ubuntu first get the drivers from www.3dconnexion.eu/service/drivers.html
then
sudo apt-get install libmotif3 mkdir -p /tmp/3D3dxware-linux cd /tmp/3D3dxware-linux cp ~/Downloads/3dxware-linux-v1-8-0.x86_64.tar.gz /tmp/3D3dxware-linux tar -xf 3dxware-linux-v1-8-0.x86_64.tar.gz sudo ./install-3dxunix.sh
answer yes, 4, yes.
That’s it, you might get an error saying: « Red Hat EL 7 currently not supported for automatic driver startup. ». This is not a big deal as we can start the daemon by doing:
sudo /etc/3DxWare/daemon/3dxsrv -d usb &
to test if all works, launch
/tmp/xcube
I’ll play around more to see how it goes.

QGIS Welcome Page – OPENGIS.ch

Tue, 18 Aug 2015 00:00:00 +0200

Whenever you start QGIS you basically do it because?
Right, because you need to do GIS work. Ah, how I love rhetorical questions to start a post.
And most of the time one continues to work on a QGIS project which he has prepared before. For me 99% of the time, I start QGIS, move the mouse to the top left over « Project » go to « Recent Projects » and select the one I want. If I am lucky my hand is stable enough to hover « Recent Projects » and not « New From Template » which I actually never use.
No longer!
At OPENGIS.ch we just introduced a nice « Welcome Page » to QGIS which lists the recently used projects. With a screenshot next to it!
That’s how my QGIS looks at start right now:

Instead of the filename it will show the project title if one is defined.
And you get some recent information about the QGIS project just next to it.
I would never want to miss this feature again.
… Coming soon to a QGIS near you …

Syntactic sugar for PyQGIS – OPENGIS.ch

Wed, 12 Aug 2015 00:00:00 +0200

If you are a python coder you probably already know the with-statement.
If yes, you can directly jump to the with edit-section.
If not, here’s a short summing up.
If you want to edit a file you can do:

f = open('file', 'w')
do_some_changes_to(f)
f.write()

This is a bad idea. The file is not closed and you should always do that. We can easily add that, right?

f = open('file', 'w')
do_some_changes_to(f)
f.write()
f.close()

Now what happens if do_some_changes_to(f) causes an exception? f.close() is never called.
You may remember something called finally. That can be appended to a try-block and will be executed in the end no-matter-what.

Postgres Expression Compiler for QGIS – OPENGIS.ch

Wed, 29 Jul 2015 00:00:00 +0200

Performance

This project is all about performance of QGIS with a postgres/postgis database.
A lot of people have QGIS connected to postgres/postgis (if you don’t: it’s a great combination in the open source geo stack). Databases are really optimized for querying. They keep indexes of geometries to be able to find them faster, they keep indexes of attributes to filter faster – and finally they often run on powerful servers.
QGIS tries to be smart enough to make use of this additional information. So whenever a map canvas is being rendered it asks the database only for features in this area. But if it’s about other attributes, QGIS filters by them locally. This means if you have a list of all the cities in the world and only want the capitals, QGIS will get the list with all the cities from the database, check for every city if it’s a capital. If it’s not, it will discard it, if it is it will use it. That’s terribly slow and postgres itself could do it much faster.
That’s where the postgres expression compiler comes into play. It is able to compile QgsExpressions (an SQL dialect) to postgres filter queries (another SQL dialect) and sends the converted SQL to the server if it is able to create matching SQL. If not it will gracefully fallback to the (slow) local evaluation.

QField in the wild – OPENGIS.ch

Mon, 15 Jun 2015 00:00:00 +0200

QField app QField Karma edition app QField Experimental is out, after a couple of months of requirements gathering, private early alpha testing and foremost tons of emails requesting access to the testes group we decided today to put the current BETA version in the playstore. This means that from now on you can install QField just like any other android app by using the playstore.
It is important to remember that QField is still beta and thus it doesn’t have all the features we want yet. Notably, there is no digitizing, due to a bug in android, Android 5 (Lollipop) is currently not supported (android 4.3 and 4.4 are suggested) and for now you need to manually copy the projects and data from the desktop to your device.
QField is an Open Source project led by OPENGIS.ch LLC, more information, the source code and a possibility to donate to the project can be found on the QField page (preferred) or by buying the QField for QGIS Karma edition app.
Also if you need a specific feature, contact us to sponsor its development.

QGIS Quality and Testing – OPENGIS.ch

Mon, 01 Jun 2015 00:00:00 +0200

I promised that I will write a bit about what I’ve been up to at the last QGIS developer meeting – apart from the social part we also got some work done there.
So let me start with something that really matters to me and I think can make a big impact.

Unit Testing

At the start of the developer conference Alessandro Pasotti asked me to do a workshop on unit tests. We quickly squatted a room with a couple of other people where we discussed the general system of unit testing in QGIS and a small unit test has been implemented. The idea definitely got some traction as a couple of hours later a pull request with a similar test was ready for merge. Thank you very much Tobias Reber!
It should turn out, that unit testing should keep me busy at this place for some more time. It was very interesting to see that the unit tests which we have really do their job. And their job is to fail (You can see what’s going on here https://travis-ci.org/qgis/QGIS/builds). More than once tests failed for pull requests and some code could be brought into good shape before being integrated.
Another interesting thing to see was, that sometimes a pull request got merged even though it failed. I assume this is due to the fact that some of our unit tests sometimes fail (mainly the ones which require external services) and therefore condition developers not to look too close at the result of the tests. Bottomline for me: prefer to disable unstable tests. It’s easier to interpret the testing result if the noise is removed.
And finally another work I did on the unit testing was related to the Postgres Expression Compiler (more about it in a future post). This is a new implementation which allows some requests to be filtered on the database server instead of the client itself. I didn’t want to leave it alone from unit tests, so I wrote some tests that check if a bunch of sample requests filter the same set of features on the database as they do locally. This requires a postgres/postgis server which we didn’t have to test before. Fortunately we can run that directly on the travis-ci infrastructure (that’s where QGIS gets tested after every change in the code). But then I thought that if we already have a running postgres/postgis server, why only test some expressions. And I started to add further tests for basic functionality like querying the extent, getting default values, filtering by spatial extent and some others.
While doing that I realized, that it’s not only postgres/postgis that should pass these basic tests, but basically any provider. So the code was refactored out into a more generic base class to be able to implement this for various providers and keep adding more tests at one single point. Now the same code tests also SpatiaLite and Shapefiles. That’s really nice because this way we can check if all providers act the same and discover inconsistencies. For instance, when introducing the Shapefile tests it turned out that when selecting features in a given spatial extent not only the features in there but also features without a geometry have been returned. A rather odd behavior that none of the other two providers showed. It’s fixed now.
I am looking forward to seeing the suite of unit tests grow even more and helping QGIS to become more stable.

Tak Nødebo – OPENGIS.ch

Wed, 27 May 2015 00:00:00 +0200

After a week with QGIS members from all over the world we arrived back home and can say that once again, the QGIS developer meeting #13 was a great event.
It started with the QGIS User Conference where a lot of interesting talks from experiences in day-to-day usage to low-level technology insights could be attended. Tim Sutton in the end took the chance to shortcut users and developers directly, asking for feedback and advice – a great way of reducing the gap between development and usage. Also outside the conference rooms it was great to talk to all the users, developers, geo-geeks, to have interesting discussions and to hear how the software we produce is being seen, where it rocks and where it requires more polishing.
The second day of the User Conference was all about workshops and a everybody could get some insights into new topics or get a more profound understanding of possibilities and techniques hands-on. I haven’t attended any workshop myself but I have heard from several people that they were totally worth the time.
The rest of the week it was all about development again. That’s what I thought at least in the beginning – but it turned out that it was much more socializing than development. Which is not necessarily a bad thing! Finally I still got around to do some development done, which I will try to sum up in a later post here.
One thing that I always enjoy is to be able to practice languages. Thank you Violeta, Mar, Paolo, Victor and so many others for the Latin language part! (I don’t even start with English or this page will be too long)
The usual suspects were present as expected but also many new faces could be seen. It is awesome to see how this event gets more attraction and visitors every year!
One of the best things about it is that there is so much knowledge around and that the decision circles are really short. Regardless if some questions you may have are related to QGIS, other FOSSGIS, general open source, geo-spatial or whatsoever, you can be sure that the right people will be there to talk about it and finally get the ok to do something or a good reason not to do something.
If you have never been to a developer meeting or a user conference, you should definitely consider to go there if it is coming close to you. It will be good for you to talk to everybody and it will be good for everybody to talk to you!

Performance for mass updating features – OPENGIS.ch

Wed, 29 Apr 2015 00:00:00 +0200

This post discusses how to improve the performance of pyqgis code that updates a lot of features by a factor of more than 10.

Scenario

Once in a while you want to modify every feature of a layer. Or a bunch of features meeting certain criteria. That’s pretty straightforward. Let’s say you want to shift them all in x direction by 0.1 and in y direction by 0.3 (map units).
Straightforward and easy to do:

A star is born, QGIS mobile is now QField – OPENGIS.ch

Wed, 28 Jan 2015 00:00:00 +0100

It is with great pleasure that we want to announce the new name for what was briefly known as QGIS mobile.

Please welcome QField for QGIS™!

After long thinking about various names and variants including QGIS mobile, QTouch, OPENGIS.ch QGIS mobile, QWork, and many more, we felt that QField represents best what we want to archive. A field data capture and management app fully compatible with QGIS™.
QField allows you to take your QGIS projects out of the office for effective field work. By maintaining QGIS’ styling and edit widgets QField greatly reduces preparation time.
QField is an Open Source project led by OPENGIS.ch LLC with the whole development happening on Github. Currently we are running an invite-only alpha testing but as soon as the app will have a bit more functionality we will widen up the testers group.
QField will be released for free on the Playstore with the possibility of donating to the project via paypal (preferred) or by buying the QField for QGIS Karma edition app.
Another way to greatly help the project is, if you need a specific feature, contact us to sponsor its development.
QField is built from ground up to be touch oriented and easy to use outside and follows the following paradigm:
● GPS centric
● QGIS desktop compatible
● Fully working when offline
● Synchronization capabilities
● Project preparation on desktop
● Few and large buttons
● Switchable use paradigm (Display, Digitizing, Measuring, Inspection,…)
QField is built using Qt5, QtQuick 2 (both are supported and suggested by Qt) and OpenGL so it is future proof and it spearheads QGIS towards Qt5.
For feature requests, please contact us
For bug reports contact us or better file an issue on Github

The QGIS mobile 0.2 video demonstrates some basic functionality like navigation, feature identification and attribute editing.

Happy new year to the power of two! – OPENGIS.ch

Thu, 08 Jan 2015 00:00:00 +0100

For the first time we at OPENGIS.ch can celebrate with 2 people, Marco Bernasocchi and Matthias Kuhn both experienced QGIS developers and holders of a Master degree in GIScience.
After having worked individually in the last years, we have realized that there is a huge potential for us to join our knowledge – because the whole is greater than the sum of its parts. This is why starting from January 1st, 2015 we are working together as OPENGIS.ch LLC.
Marco is the creator of QGIS for Android, has a strong background in python and web applications development and is core committer of the the award-winning InaSafe project.
Matthias is an active QGIS core committer with a long history in developing in a wide variety of programming languages and areas from embedded systems to server services.
We both are strong believers in open source software and are convinced that developing in the public is a big win for everybody.
Among other projects, we are currently working on QGIS Mobile. A touch optimized interface for field work, based on the QGIS libraries. Make sure you keep an eye on this project as it is in its infancy but growing very fast.
If you have a use-case for it and would like to support its development don’t hesitate contacting us. We will happily provide you with a preview version.

Help mapping the Philippines – OPENGIS.ch

Sat, 16 Nov 2013 00:00:00 +0100

Hi, last night I helped teach some students of the UP (University of Philippines) how to do remote mapping for OSM (openstreetmap.org) data. It is extremely easy, just go to tasks.hotosm.org, login, choose a job, read the workflow tab, select a task (in the task tab) and finally click on ID. An online editor will open with the explainations you need.
Go have fun helping
Thanks Marco

Help Coron after Typhoon Hayan – OPENGIS.ch

Tue, 12 Nov 2013 00:00:00 +0100

Don’t use the donate button on the right, use the button at the bottom
Hi all, as some of you know, I’m in the Philippines right now, on a WorldBank mission to help teach an open source planning, preparedness and response tool (inaSAFE) to locals.
I’m in Manila where all is good. Hayan didn’t hit here and while it was hitting hard on the central and southern Philippines, I was safely in the north thanks to Dirk Fahrenbach (in CC) which told me not to head south to go diving (I hadn’t checked the weather forecast 10 days ago yet).
Unlike some other dive operators (not all of them, but he was the first to warn me and has actively been reaching out) which told me yes, no problem come dive to Coron the weekend, Dirk openly warned me not to go there when the typhoon path and strength were still uncertain.
I don’t know Dirk personally, and he didn’t ask me to do this (this is just one way I try to help), but I’m convinced that he is a very good soul and that if you can, you should consider sending some money to help the people there rebuild their homes and lives.
I’m sure you all have seen pictures in the media to realize the extent of the catastrophe and need no further motivation.
Below I forward you the support email send out by Dirk which includes details on how to transfer money directly to him via his German and Filipino bank account.
If you don’t want to do an international wire transfer, I setup a Paypal donate button in my account on which you can simply and safely donate using various credit cards. I will then then transfer all the money to him together with my donation.
to donate via paypal, please use ONLY this button, the one on the sidebar is for my opensource GIS work:

QGIS for android does not run on Galaxy Tab 3 (nor on all intel based tablets) – OPENGIS.ch

Thu, 07 Nov 2013 00:00:00 +0100

Update 2020: QField, the successor of QGIS for android supports ARM v7, ARM 64 bit, x86 and x86_64.
Hi all, just a quick note to remind you all that currently QGIS for android runs on ARM v7 tablets only. I currently have no time to make an x86 build and since I got two emails asking why the galaxy 3 didn’t run qgis I wanted to put out a quick warning. And remember to contribute to the tested device list here

QGIS 2.0 nightly features review – OPENGIS.ch

Wed, 25 Sep 2013 00:00:00 +0200

The last few weeks have been super exciting and intense in terms of QGIS development. I’ve been working a lot and sleeping little to get the latest and greatest stuff to you in the nightly packages.
Here a non exhaustive list of what is getting into this awesome package:

Updated to QGIS 2.0.1
updated the full library stack to the latest releases (including GDAL 1.10.1 -with mbtiles and spatialite 4)
made a simplified base GUI
updated the java part
improved stability
readded qt menues
added rendering notification in canvas
updated icons

Beside the whole UI and stability work, the nicest feature is probably the mbtiles support. mbtiles are raster tiles in a sqlite database and are blazing fast, have a look at it in the video below.
For now, you still need to use the QGIS installer, but i’m already working on a strategy to soon get the package in the play store, so stay tuned for more super exciting android QGIS times to come, and of course, if you or anyone you know can buy me a glass of wine I’ll be a merry coder 🙂

QGIS 2.0 for android is getting there – OPENGIS.ch

Sat, 21 Sep 2013 00:00:00 +0200

After two very android QGIS centric weeks I’m very happy to point you to last night nightly build that includes a lot of new improvements, better stability and of course all the super cool features of the freshly released QGIS 2.0.
So, go ahead, get the installer, get the latest nightly and let me know how it goes.
There are two known issues that I’m still working on (beside python support):
– There is no styling UI, but if you load an already styled project all works nice.
– When digitizing, don’t use the enter button in the android keyboard to confirm the attributes form but just close the keyboard and use QGIS ok button.
So, enjoy it, let me know how it goes, remember it’s alpha and maybe buy me a glass of wine 🙂

InaSAFE wins Open Source ‘Rookie of the Year’ award – OPENGIS.ch

Sun, 24 Feb 2013 00:00:00 +0100

From Tim’s post:
A couple of weeks ago I had the pleasure of doing an interview on behalf of the InaSAFE project as part of the selection process for the Black Duck Software ‘open source rookies of the year’ competition. A week later we heard that we had made it into the top 10! The award is based on a selection or projects from the popular ohlog.net web site:
“Using data on open source projects from Ohloh.net and the Black Duck® KnowledgeBase™, Black Duck reviewed thousands of open source projects that were initiated in 2012 to select the fifth annual Open Source Rookies of the Year. Using a weighted scoring system, points were awarded based on project activity, commits pace, project team attributes and other factors. Black Duck determined the top 10 Rookie projects following an audit of its findings and normalization of scores.”
You can see all the winners listed at the official competition page here. We were also fortunate to be mentioned in Wired, DirectionsMag and various other places.
We have worked incredibly hard over the last year to make the InaSAFE plugin for QGIS, with a team of dedicated developers from AUSAID, WorldBank, Linfiniti, opengis.ch and a number of other developers and contributors, so it is really great to receive this acknowledgement! Here is looking to another great year of working on InaSAFE for 2013!
“We are pleased to recognize InaSAFE as one of the 2012 Open Source Rookies of the Year,” said Tim Yeaton, CEO and president, Black Duck Software. “The Rookies demonstrate how community innovation, particularly within the JavaScript and mobile projects, mirrors the need for innovation in web experiences, mobile devices and enterprise application. Being able to identify and showcase these up-and-coming open source projects is an important part of our mission at Black Duck to bring together the open source community and businesses around the world.”
Past winners of the prestigious award include Twitter Bootstrap, Cloud Foundry, Mozilla Persona (formerly known as BrowserID), Red Hat OpenShift, Eclipse Orion, Apache Rave, Salt Stack, OpenStack, Diaspora and many other notable projects.
I’m really happy to be part of this team and I look forward to more hacking (in the original sense of course) together, Great job guys

New qgis for android installer – OPENGIS.ch

Thu, 24 Jan 2013 00:00:00 +0100

So I’m finally back on working on QGIS for android. Currently thanks to
the QGIS usergroup Switzerland and norbit.de I’m porting python QGIS to
android. So stay tuned on that one.
On the side, due to a bug in the latest release of necessitas I
created a workaround version of qgis. the problem is that many people
install the latest release and miss al the menues. So today I decided to
upgrade the qgis installer and added the possibility of seamlessly
downloading the nightly builds and to clear the cache to save space on
the device. For the moment the nightly build is just the custom
workaround package but once the bug is gone I’ll restart pushing real
nightlies.
now I’d like to ask the translators if you can have a shot at updating
the installet strings (about 15) you can use github to edit xml and pull
request or .po files and pull request or just a plain email to me. here more infos on the translation process for the installer

New QGIS workaround version – OPENGIS.ch

Wed, 21 Nov 2012 00:00:00 +0100

Hi all,
Good news this time 🙂 Instead of enjoying my weekend doing some wicked diving here in Indonesia, I decided to close myself indoor and get a (re)working vesion of qgis out. As some of you might have noticed or read in my previous post, the latest and greatest version of Qt for android breaks a fundamental part of QGIS, the second level menues.
So after some good nerdy-weekend hours here it is your shiny (again-) working qgis. There is nothing new code wise, it is still alpha7 but it works again 🙂
enjoy and for all those happy people that asked me to fix this, well you know how much a full Sunday with no diving 🙁 is worth and where my donate button is 😉
oh yes, and here is the file, you will have to uninstall the old qgis manually because I created this package on my laptop and not on the server, so it has a different signature. Please test this and let me know if it works for you and I’ll release it as alpha8.
ciao

InaSAFE 1.0 Launched – OPENGIS.ch

Mon, 12 Nov 2012 00:00:00 +0100

You might have noticed that lately there has been a slight slowdown in posts about QGIS on android. There is a very good reason behind it. Since August I started working on a project called inaSAFE, a free software that produces realistic natural hazard impact scenarios for better planning, preparedness and response activities.
End October after a heavy development sprint, the InaSAFE team (which consists of developers from around the world, funded by AUSAID and The World Bank / GFDRR) released inaSAFE 1.0 at the AMCDRR, a high level conference for disaster risk reduction in Asia. During the same event, inaSAFE was even demonstrated to the President of Indonesia.
Here a description of AIFDR from Dr Trevor Dhu and here Trevor introducing Susilo Bambang Yudhoyono the President of Indonesia to InaSAFE (running in QGIS)
InaSAFE can be easly installed from QGIS by going in Plugins > Fetch Python Plugins, then type ‘inasfe’ in the filter box and select InaSAFE 1.0. InaSAFE is completely Free and Open Source (GPL v3) and you can get source code from our github project.

Necessitas Beta1 \"breaks\" qgis on android – don't update – OPENGIS.ch

Thu, 25 Oct 2012 00:00:00 +0200

Hi all, it has been a while since my last post, and foremost QGIS on android release. I’m very sorry. I’ve been working hard on another project (inasafe.org) that toke up all my time since we just launched version 1.0.
So now to the real problem, necessitas (the android Qt port) has had a sweet update that adds a lot of nice things (like native look and feel) to Qt apps. The only problem is that it has a grave bug that makes the new shiny thing bad for QGIS. Basically there is no second level menu bars anymore. Yes exactly, every item like view>panels>gps can’t be selected. Basically all plugins, all panels and more can’t be selected with the new necessitas, So If QGIS is the only Qt app you have on your device, DON’T let ministro update it’s libraries.
I’ve of course already discussed with the maintainer of necessitas and he promised me to have this fixed in the next release. Meanwhile, I’m looking into making a temporary package that includes the old Qt libraries.
I’m sorry for the issue and really hope to solve this quickly but as everybody I need do do paid work as well to support my other developments, so if you can, give a nice poke to that donate button 😉
ciao

MTP is probably the most annoying thing I encounter lately on tablets, why don’t I get a simple USB mass storage when I connect my tablet? here some hints on how to get (maybe) rid of mtp in ICS (android 4.0)
Just change the connection mode to Mass Storage or PTP instead of MTP, under Settings > Storage in the dropdown menu (or using the context menu button).

QGIS Swiss user meeting 2012 – OPENGIS.ch

Tue, 05 Jun 2012 00:00:00 +0200

Yesterday I had the possibility to present QGIS on Android at the QGIS Swiss user meeting 2012 held at the Bern University. In the morning I held this presentation and in the afternoon I leaded a small workshop where we discussed more in depth how qgis of android works. I’d like to thank the QGIS user group Switzerland for organizing and the sponsors for supporting such a nice event.

New Website Online – OPENGIS.ch

Tue, 22 May 2012 00:00:00 +0200

So, after a very succesful rainy weekend the long-standing project of a new website is finally reality. Thanks to this project I had the chance to check out with no client constrains what was out there to allow me doing what I wanted. After an in-depth review I decided to use WordPress with the customized Shell-lite theme and some plugins.
Now, to the why, well I really love the way WordPress has evolved from a simple blogging platform to a much more powerful CMS while keeping its super slick and easy admin panel. Simply great, possibly the best I know of.
The shell-lite theme is a GPLv3 parent theme that I liked from the beginning on for its slick typography and simple almost black and white design, kudos to the developers. I created a child theme to change some things in the home and in the archives pages and inserted a Featured articles widget with a custom theme to my new home.
What I still need to do Is to translate the site using wp-i18n and upload the new logo as soon as I get it. As well I want to see If I’m happy with wp-touch as a mobile front end or if I’ll implement a new theme for it. We’ll see.
In any case I think that it is pretty amazing to what result you can come in about 20 hours of development.
Enjoy and let me know if you find any issues.
ciao

QGIS @ 4200m – OPENGIS.ch

Sat, 12 May 2012 00:00:00 +0200

One of the nice things of being freelance it that you can work on Sundays when the weather is horrible and get out on Tuesdays when it rocks 😉 .
So Tuesday I decided to go test QGIS at high altitude and went to the Breithorn and the Pollux with my best friend for a nice winter end tour.
At the summit of Breithorn I took out my Galaxy, started QGIS and opened my basic project, turned on GPS and voilà… it all worked… even in high winds and -15°C 😉
Definitely time to get involved in using it and supporting its developement.
ciao Marco

QGIS on Android using external GPS receivers – OPENGIS.ch

Tue, 01 May 2012 00:00:00 +0200

Thanks to FORNAT AG which sponsored me I could spend some time looking for solutions to make QGIS on android working with an external GPS receiver that sends NMEA strings.
It all boils down to the following:

via bluetooth works
via USB not yet (as soon as I get more sponsoring or time I’ll look more into it since I’ve some ideas).

To use an external bluetooth GPS you have to follow six easy steps:

QGIS on Android Phone – OPENGIS.ch

Fri, 30 Mar 2012 00:00:00 +0200

At FOSSGIS I was asked to try to install qgis on a very small android phone, I think it was a 3.2″ screen. the install went smoothly after making some space but then the problems came because of the small screen.
Eventually I thought about setting a smaller font size to make the UI scale more, the problem was that it was impossible to get to the size setting because the UI was to big.
As a workaround I created a QGIS.conf file with this content
[General] IconSize=32 fontPointSize=4and pushed it to the device using the android debug bridge like this:
adb push myQGISConfigFile.conf /data/data/org.qgis.qgis/files/Settings/QuantumGIS/QGIS.conf
On the next start the whole gui was nice and small and fitted the screen.
Here some screenshots from my Samsung galaxy 9000 with 4″ screen and a video demonstrating digitising (with pen and fingers), GPS, compass and zooming on the phone.

QGIS for android alpha 7 – OPENGIS.ch

Thu, 01 Mar 2012 00:00:00 +0100

7, my luck number… So here you are, the latest and greatest QGIS for Android.
This release includes the super new pinch zoom tool, should have no blocking dialogs anymore (i fixed the attribute table) and the help->about shows now from which commit the package has been created.
The packages containing armeabi and armeabi-v7a code are still less stable that the armeabi only packages (the ones with the -armeabi suffix) which are still the preferred. For the moment the release packages are built with Debug symbols as well.
I hope you will enjoy this release, and remember that if you or anybody you know can help sponsor the development I would greatly appreciate it.
Btw, noticed the nice new yellow PayPal donate button ;)?
Ciao Marco

QGIS for android gets Pinch zooming – OPENGIS.ch

Thu, 01 Mar 2012 00:00:00 +0100

Well, it is a super winter and there is a lot of snow here in Switzerland and all this makes me super happy which means that my productivity increases… here you are, the last and greatest improvement for QGIS on android: a fancy zooming map tool like you know from other applications like google maps.
The tool allows for:

panning
pinch zooming
double tap zoom in with Center
twofinger tap zoom out

Furthermore I added a close button to the attribute table so that there are no blocking dialog left. The attribute table doesn’t look perfect yet, but works well (a workaround to make it look better is to force it into a dock-widget by checking « Open attribute table in dock window » under Settings->Options->General
I’ll release soon a new version and look forward to your comments and support.

QGIS for android alpha 6 – OPENGIS.ch

Thu, 23 Feb 2012 00:00:00 +0100

Hi all, release time again… happens that just couple of hours after i pushed alpha5, the necessitas framework received a new update [1] that addresses some important issues. Meanwhile I managed to compile GEOS and GDAL with armeabi-v7a optimizations

QGIS on android ALPHA 5 – OPENGIS.ch

Thu, 23 Feb 2012 00:00:00 +0100

Hi all couple of days ago I pushed a new alpha version of qgis for android on android.qgis.org
This release includes all the goodies that I got to implement lately including: – right click support through longClick – shape file support – gps – compass – android 4 support – partial hardware optimization for armV7a (most newish devices have it) – no debug symbols
I m very happy with this release because it adresses and fixes all high priority bugs. Adding support for a armv7a optimized whit no debug symbols build increased greatly the speed of the app. The package you need to install is the same and includes both armv5 and armv7a code. Android will take care of using the correct version. Gdal and geos are not available yet in v7a code so the v5 versions will be loaded. I couldn’t test much the v7 code so I hope you can help me testing it. As well, on www.opengis.ch I published many videos and screenshots of qgis. As usual, please remember if you can (or if you know anybody that could) that sponsoring would help a lot implementing some more great features.
Ciao

QGIS on ANDROID talk at the Università degli Studi di Urbino – OPENGIS.ch

Wed, 14 Dec 2011 00:00:00 +0100

Yesterday, thanks to Prof. Mauro De Donatis who invited me, I held a 2h talk at the Università degli Studi di Urbino about QGIS and QGIS on Android. The talk was attended by around 50 students and staff from Computer science, Geology and Ambient sciences.
I liked finally holding my first speech in Italian, although i felt more comfortable with English slides 😉
Here you can find the slides. Thanks a lot to Tim Sutton Sutton for letting me use part of his QGIS for Humanity presentation

Creating non-versioned shared libraries for android – OPENGIS.ch

Wed, 23 Nov 2011 00:00:00 +0100

While porting QGIS to android using necessitas I encountered the problem of versioned libs. Android does not support versioned libs and it is not going to. In the first vesions I used rpl -R -e libqgis_core.so.1.9.90 « libqgis_core.sox00x00x00x00x00x00x00 » $APK_LIBS_DIR and similar hacks to remove the version from the libs. But it was rather hacky. Then I found this post by Tom Russo where he mentioned how he changed his build process to force non versioned libs. I wrote him with some questions and finally, thanks to his hints, I managed to create a fairly general patch for libtool to make it generate android compatible configure scripts. I sent the patch to libtool and we’ll see what they think.

Sharing internet connection – OPENGIS.ch

Sat, 01 Oct 2011 00:00:00 +0200

Today, for some bizarre reasons only my android phone was connecting to a WiFi. So I decided to use it as a tethered modem. The problem was that my friend Bruno could not use the net either, so since networkmanager ad-hoc networks were not working and it is our day off climbing we decided to keep our fingers trained on the keyboard.
Here are two little scripts to create an adhoc Wifi and forward internet connection over it.
enjoy Marco (and Bruno)

GSoC 2011 final report – OPENGIS.ch

Wed, 24 Aug 2011 00:00:00 +0200

So, it is over, after 3 months working on QGIS for android as a Google Summer of code project it is now time to wrap up what I did and didn’t do.
First of all a QGIS android app exists now and it has many features including:
– reading/writing projects
– raster support
– spatialite support
– wms support
– (apparent – untested) wfs and postgress support
– partial shape files support (string attributes still chrash the app)
– Fully functional gui (SymbologyV2 doesnt work yet)
– (all?) core C++ plugins beside globe (any takers? 😉
Further more I created a series of build scripts that make it easier to set up a dev environement.
Unfortunately I didnt manage to implement live GPS tracking and a larger gui optimisation, but all in all I’m very happy with the results and seeing that few peoples are already testing it. Soon ill publish a video.
cheers
Marco

QGIS Android the first test map – OPENGIS.ch

Today I loaded the first data into qgis and although the mapcanvas stays black, in the map composer the data is shown. Here some screenshots.

QGIS data providers and map canvas – OPENGIS.ch

Fri, 19 Aug 2011 00:00:00 +0200

After finishing with the gui(see previous post) i started testing the data providers.reading and writing shp files always ends in an app crash. Loading rasters, wms and gpx seems to work but the mapcanvas is never drawn. I have to investigate why. But probably it has to do with the draw used in qgis. The properties are there and get updated, but the canvasstays black. The same happens with decorations plugins like north arrow and copyright.
Next things i want to check is the shape error and the canvas problem. Then probably sqlite and gps.
Ciao Marco

QGIS on android has complete gui and supports translations – OPENGIS.ch

Fri, 19 Aug 2011 00:00:00 +0200

Hi I just managed to create an apk with al the resources needed by qgis. On the first runrun the application extracts this file to the proper location a thus the gui is now complete. This means as well that translations and crs databases now work properly. The gui works nice beside some small glitches. It is usefull to go under settings->general->icon size and set it to 32. The only inconvenient at the moment is that at the first startup the app shows a blackscreen while its copying the files for about 30 to 60sec so just be patient and remember that the whole app will takeup to 230mb (it installs on external storage by defaut). I tested th install on my transformer 3.2 and my galaxy 2.3.3and the install works flawless on both.
I wonder if this solves the « squares text problem » also. Tomorrow i ll do a video and will post it.

QGIS on Android has a proper GUI – OPENGIS.ch

Thu, 18 Aug 2011 00:00:00 +0200

Today I managed to get QGIS to load all the icons, providers and plugins. The GUI looks very good and quick, it is easy to use with the finger, beside the small arrows hiding multiple icons.
Furthermore I discovered that customization works so that we could pre configure qgis to show bigger icons (as in Settings->Options->Icon size 32) and a subset of tool bars, all in all is cool how good it runs.
To be noticed that the gui now works properly as well on my mobile phone (Galaxy s)!!!
Now I’m tackling all the files like i18n, resources, svg and so on.
Here a video showing the newest stand of qgis for android and on my github you can download it.

QGIS on Android – OPENGIS.ch

Wed, 17 Aug 2011 00:00:00 +0200

Hi all, it is a pleasure to announce that I finally got Quantum GIS to start on an android (3.2) tablet (Asus transformer). I tested as well on a Samsung Galaxy phone with cyanogen mod 7 RC1 and it works a well (with the obvious screen size limitations).
Qgis still doesnt load many elements, but the gui is there and the rest should be only minor issues. I’ll post more as soon as i make further developments. Meanwhile, if you want to test the apk, you can download it from my github here. For building your own, have a look at qgis wiki

GSoC 2011 weekly report #11 – OPENGIS.ch

Sun, 14 Aug 2011 00:00:00 +0200

This week Imanaged to get libqgisapp.so to build automatically if cmake is passed -DANDROID. as well I managed to implement all the JNI stuff that comes from necessitas. Apk file gets installed and the app tries to start but it silently fails after startQtApp is called succesfully. Logcat shows no message or anything. This week I’ll investigate this problem and hopefully get it all to run, this part was definitively tougher than planed.

GSoC 2011 weekly report #10 – OPENGIS.ch

Tue, 09 Aug 2011 00:00:00 +0200

This week I finally managed to get a test Qt application packaged as an apk file. The application uses the native Proj lib to do some projections conversions. Basically it does the same as what qgis will do just with much more dependencies.
The key problem was that necessitas wipes the libs directory when it generates a project and the native libs never get pushed to the device (bug report). As well, when they get pushed, for example by using the ant Task, then there was a versioning problem. Android does not support (and won’t in the future either) versioned libs, so I had to find a way around it. I came up with two solutions, the first is a custom java method in the QtActivity class that creates symlinks or copies the libraries on runtime and loads them accordingly. the other involves editing the SONAME of each lib and padding the versioning with 0 using the rpl program (rpl -R -e libexpat.so.1 « libexpat.sox00x00 » $INSTALL_DIR/lib). I dont know yet which approach to keep, but they both work properly.
I updated all the scripts to be cleaner and I’m working now on creating the libqgisapp.so once I have this all the app should be hopefully ready.
As well, I tried the full over th air deployement of the test app on a real device and it all works, just click on the link to the APK arm-V5 APK arm-v7a and all dependencies (Qt libs as well) get installed… pretty amazing 🙂

QGIS Globe runs on Win – OPENGIS.ch

Tue, 02 Aug 2011 00:00:00 +0200

I just set up a win xp virtual box (remember to enable 3D acceleration) and to test out globe on windows. here what I did:
Get OSGeo4W installer and run it
Choose advanced install
Select qgis-dev, osgearth-bin, osg-bin from the desktop packages
Select osgeart-dev, osg-dev from libs
Run
Open Qgis, activate the globe plugin in plugin manager, click on the globe button and post here your success stories 😉

GSoC 2011 weekly report #9 – OPENGIS.ch

Fri, 29 Jul 2011 00:00:00 +0200

This week I managed to cross compile qgis and started working on packaging it. See the previous post for more details.

QGIS cross compiles using android NDK – OPENGIS.ch

Thu, 28 Jul 2011 00:00:00 +0200

Finally I managed to cross compile qgis using a NDK r5c standalone toolchain. Currently the scripts to produce the binaries require the necessitas qt source to be present on the host since QtUiTools need to be compiled as well. This should be only until QtUitools is included in necessitas (maybe in the next release).
For the moment only the basic library (gdal, geos, qwt, expat, gsl, sqlite and proj) are ported but they allow already a lot. The next lib (on which i already spent some time) is spatialite with its (problematic) dependency iconv.
More important than spatialite is to actually bundle the binaries in an apk and to be able to run it on android.
This is all new terrain for me but i m confident that if i mastered cmake i can master necessitas and the likes… 😉 I started looking at it today and plan working on it tomorrow.
Once I get qgis on android or maybe when i ll be fed of fighting necessitas i ll implement the vertical scrollbars in the dialogs that still need it. And then Gps is still on the plan.
So thats it for the good news of this week 🙂

GSoC 2011 weekly report #8 – OPENGIS.ch

Sun, 24 Jul 2011 00:00:00 +0200

This week I fought against libiconv and spatialite that did not want to properly crosscompile. Due to time pressure I decided to temporarly work on it and moved on compiling qgis. I get to the linking part of the process where I get many errors. I m now looking into them. Furthermore I refactored the scripts to be more solid and I did a major wiki update (added errors, added how to, cleanup,…). I m now a week late on my schedule and I Hope to finally get qgis to compile soon.
Ciao Marco

GSoC 2011 weekly report #7 – OPENGIS.ch

Sun, 17 Jul 2011 00:00:00 +0200

This week I was at a mountaineering course so I could only work in the evening/nights. despite of the lack of time I made some nice progresses, I got qgis to configure properly (for some reasons it still needs to run twice) and to start compile. while compiling I run into the problem that qreal are typedef to float when compiling from arm, so I patched qglobal.h to remove the float typedef and set it to double. According to the documentation this has to do with performance issues. So it might be god to check this in the future. The alternative (cleaner but immensely longer would be to replace every appearance of « double » with qreal in the full source code of qgis.
After solving this problem, the compilation went further and got stuck at the compilation of internal spatiallite, since libiconv is not present. Right now I’m trying to compile it but I’ve some errors happening.
By the end of this week I hope to be able to finally have qgis compiling and to start daling with the UI and GPS.

GSoC 2011 weekly report #6 – OPENGIS.ch

Sun, 10 Jul 2011 00:00:00 +0200

This week I started cross compiling qgis and encountered some problems that I could’t solve yet but I’m working on it.
UPDATE: I just managed to have QGIS to properly configure, by using -DQT_QTUITOOLS_INCLUDE_DIR=/usr/include/qt4/QtUiTools since it appears that necessitas has no QtUiTools yet. I’ll look into it.
UPPDATE2:or maybe not… got more errors now 🙁
As well I met with my mentor and we discussed the next steps needted after qgis compiles. We decided which toolbars where needed and that we would start by preconfiguring the install using the new configuration tool. As weel we had a look at which dialogs are not adapted for te screen of a tablet. Finally we had a look at how the GPS can be integrated and identified the useful classes. Here the results.
Needed toolbars
*Navigation
*Layer load
*basic digitizing (add, move nodes)
*infotool
*attribute table
*measurements
*layer legend
GUI Adaptations
*Layer properties add scrollbars
GPS
core/gps
app/gps
qgsGpsConnection sub class with parseData() (like nmeaConnection)
QIODevice subclass listening to android gps api and emitting readyRead()
extend QgsGpsDetector$
Next week I’ll focus on getting qgis to cross compile.
As soon as I’ll be done, I’ll start adding the vertical scrollbars to the gui dialogs that don’t have them (only the layer properties dialog) and then to support the GPS. Finally I’ll configure the toolbars.

Globe is in QGIS Trunk – OPENGIS.ch

Wed, 06 Jul 2011 00:00:00 +0200

Last night Pirmin committed our Globe plugin to the QGIS trunk. this means that getting the needed dependencies (see below), building QGIS with -DWITH_GLOBE=ON and activating the plugin its all it takes to get a super globe running on QGIS.
Dependencies:
sudo apt-get install osgearth osgearth-dev openscenegraph (should be enough)
WARNING: it appears if you don’t install osgearth-dev, then the plugin will compile fine but will not be available for activation in the plugin list.
Installer: I updated the Installer Script although it is not really needed anymore since you just have to compile QGIS.
I’m not aware yet of the dependency packaging situation for OSs other than ubuntu.
Ciao Marco

GSoC 2011 weekly report #5 – OPENGIS.ch

Tue, 05 Jul 2011 00:00:00 +0200

This week I re-factored the install script to make it cleverer, compiled expat library, fixed the last problem that was blocking GDAL from installing and compiled QWT library using necessitas. As well I started and started looking on compiling qgis and how to add external libs to a necessitas package.
This week I’ll be mainly looking into how to compile QGIS to have it running on Android.

GSoC 2011 weekly report #4 – OPENGIS.ch

Fri, 24 Jun 2011 00:00:00 +0200

This week i finally got PROJ, GEOS and GDAL to compile and install. I updated all the instller scripts to use the NDK stand alone toolchain, using Android.mk files turned out to be more a hassle than useful. Furthermore using the standalone NDK toolchain the compire process can be totally scripted and thus integrated in bigger build systems. I started working on QWT as well and I plan to finish it next week. next week I plan as well to look into sqlite support in android (should already be there so no problem) and to look at flex and bison which are needed during the compilation of qgis.
Next week I’ll meet as well with Marco to discuss further developements.

GSoC 2011 weekly report #3 – OPENGIS.ch

Sat, 18 Jun 2011 00:00:00 +0200

This week, I worked on trying to get Android.mk files working, it looks like using the Android Toolchain standalone (I found in the docs how to use it cleanly) was more fruity, I started working on cross compiling GDAL and it looks not too bad. Using makefiles got me to more compile mistakes than anything else. Next week I’ll discuss with Marco what we should do (use android.mk or not).
The plan for next week is to finish off working with GDAL and start looking at QWT.
This week I also tried the new NDK to see if it made any difference but id does not look like.
The new scripts are in github
Cheers Marco

GSoC 2011 weekly report #2 – OPENGIS.ch

Fri, 10 Jun 2011 00:00:00 +0200

This week I managed to crosscompile PROJ 4.7.0 and created installer scripts for it and for GEOS, which gets to the linking step. but then stops due to the absence of STL in android. diggig into the problem I discovered (I’m almost ashamed) that the NDK docs explains how to deal with that problem (big RTFD to myself). So now I’m carefully reading the NDK docs and started experimenting with ndk_build script.
Next week I want to create ndk make files for this two libs and start on working on the next ones. I’m finally starting to understand the whole picture.

GSoC 2011 weekly report #1 – OPENGIS.ch

Tue, 07 Jun 2011 00:00:00 +0200

all, this week i leaped more int the cross compile realm. Geos almost done and started with proj4. I updated my necessitas infrastructure to necessitas v 0.2 and we decide to target android 3.0 which is optimized for tablets. I havent updated the wiki yet since i’ve been (and still am) mainly offline at the moment. On the dev list of Qgis tere have been interesting discussions about the needs of qgis mobile. Pity they started only now. Next week I ll continue crosscompiling and resume the list discussion on the wiki. Ciao Marco (sent from Marco

so the first (almost) week Is over. In this week I couldn’t do much since yesterday I finally graduated. Any how I managed to squeeze into the week some work (together with stuff I had done the previous week).
I finished setting up everything and I got a first Qt test application running on android. furthermore I started looking into which libraries need to be ported.
I created a ~~Wiki page [0]~~ wiki page and a ~~github repository [1]~~ github repository for the project.
We also started porting the Proj and Geos libraries, further comments on the wiki.

QGis Globe runs on a GeoWall using ubuntu natty – OPENGIS.ch

Thu, 19 May 2011 00:00:00 +0200

After a day of work in the GeoWall lab at the GIScience Center of the Zurich University, I got QGis Globe to work in QuadBuffer stereo mode with polarization glasses.
The hardware used is a Dell Precision 390 workstation with a NVIDIA Quadro® FX 3500 Graphic card and two projectors mounted on a special rack with polarizing lenses.
The software on the software side, the mutex-globe branch was installed on an Ubuntu natty, using the classic (no effects) desktop since stereo cannot be used with the X composite extension. The graphic driver is the 270.41.06 coming from the restricted driver in Ubuntu. The modification I had to do to the /etc/xorg.conf generated from nvidia-settings file where the addition of:
Section "Extensions" Option "Composite" "off" EndSection
and within the Section « Device »:
Option "Stereo" "4"
Here the file for reference:`# nvidia-settings: X configuration file generated by nvidia-settings

QGIS Globe runs in Trunk – OPENGIS.ch

Fri, 13 May 2011 00:00:00 +0200

Thanks to Marco Hugentobler’s idea of using Mutex, QGIS Globe now runs in Trunk, i just created a dev branch at https://github.com/mbernasocchi/Quantum-GIS/tree/mutex-globe and updated the installer script at https://www.opengis.ch/2010/12/01/qgis-globe-plugin-installer-script/ (I haven’t tried it yet but it should work)

Nach dem erfolgreichen ersten deutschsprachigen QGIS Anwendertreffen am 21.4.2010 in Bern findet das zweite deutschsprachige QGIS-Anwendertreffen an der HSR in Rapperswil statt. Alle aktuellen Infos zur Veranstaltung, wie auch zur Anmeldung, finden Sie auf der QGIS Seite.
Der Vormittag besteht aus zwei Blöcken mit Vorträgen und Demos, am Nachmittag werden drei parallele Workshops/Kurse für Anfänger, Fortgeschrittene und Programmierer durchgeführt. Der Vormittag ist für alle Teilnehmer gratis, die Kurse am Nachmittag kosten CHF 120.-
Wir würden uns freuen, möglichst viele QGIS-Anwender und Interessierte begrüssen zu dürfen.
btw, it will be my first public presentation 🙂

QGis plugins: Multiview and ScattergramIdentify – OPENGIS.ch

Mon, 04 Apr 2011 00:00:00 +0200

hi All, If you deal with multivariate, multitemporal and cyclic raster data you might find interesting my multiview plugin. See screenshot of what can be done in terms of different visualizations below. The code still has some minor glitches but it is very well usable (and stable). As well here there is an improved version of scattergramm plugin that allows you to select points (or clusters on the scattergramm and have them plotted on your map canvas (it’s the screenshot as well) I didn’t publish this last (scattergramidentify) plugin because I hope to get in contact with G. Picard (author of the original scattergramm) and maybe merge the codebase. but in the meantime you might still want to try it out 🙂
ciao Marco

PyQT signals with arguments – OPENGIS.ch

Tue, 22 Feb 2011 00:00:00 +0100

so , here a snippet on how to use the different types of signals in PyQt:

connect a signal from C++
QObject.connect(self.sender, SIGNAL("signalName( Arg1TYPE, Arg2TYPE )"), self.slot)
connect a signal from Python
QObject.connect(self.sender, SIGNAL("signalName" ), self.slot )
emit a signal in Python
self.emit( SIGNAL( "signalName" ), arg1, arg2 )
emit a signal in c++
emit signalName( arg1, arg2 );

QGis Globe Plugin installer script – OPENGIS.ch

Wed, 01 Dec 2010 00:00:00 +0100

Lately, thanks to ma Master Thesis, I’ve been co-working on the Globe Plugin for QGis
here my install script for a threaded version of QGis with the Globe Plugin. By now the Globe has stereo 3D support, keyboard navigation (try all the num key), mouse navigation, a gui to control the globe and datasets can be inported configuring the .earth file. Today I’ll start implementing a dialog to add data without the need of the .earth file.
cheers Marco
UPDATE: the script is now updated to use the new mutex trunk branch and tested on ubuntu natty
UPDATE2: The script now uses the trunk repository of QGIS so it is actually not that usefull anymore since getting globe is just matter of compiling QGIS from source. I’ll leave it here for reference and « historic glory » 😉
UPDATE3: Globe runs on WIN https://www.opengis.ch/2011/08/02/qgis-globe-runs-on-win/

Ubuntu 10.10 maverick meerkat on eeepc 1005 HA – OPENGIS.ch

Thu, 14 Oct 2010 00:00:00 +0200

WOW, today I realized that Ubuntu 10.10 maverick meerkat was out and that I missed it by couple of days… bad me!!! (btw you have to select « normal updates » instead of « long term release » in your update manager’s settings).
After the update my little eeepc lookt great, and everything worked out of the box without installing a tray control (including wifi, webcam, sound, hotkeys, performance modes, ecc)!!! Great Job guys and the new unity theme is great and optimizes much better the use of vertical screen estate. The only little issue is the two buttons to disable the touchpad (Fn+f3 and the little silver button on the top left) do not work, although they are recognized by the system and give an error about being unable to enable touchpad (ensure xorg.conf is configured properly). A quick workaround is to create a script that enables/disables ONLY (see comment #3) the tapping on the touchpad and to bind it to the silver button using system>keyboard shortcuts, you’ll still get the warning but it does the job.

Custom PHP 5.3.1 with APC and XDEBUG on (Dreamhost) Shared Host – OPENGIS.ch

Wed, 17 Feb 2010 00:00:00 +0100

I’ve recently been setting up my new dreamhost for symfony projects deployment and the only thing the default PHP is missing is the support for APC (alternate php cache). So after looking at the dreamhost wiki I cleaned up and added some features to the one of the install scripts. Here it is for your/mine (future) commodity.

#!/bin/sh
# update 16.2.2010
# @author Marco Bernasocchi 
# - Added OPENSSL LIBMCRYPT LIBTOOL and a promt for installing XDEBUG
# (still uses XDEBUG 2.05, which has basic PHP 5.3.1 support. 2.1.0 is on its way)
# - removed unsupported php configure switches
# - disabled --with-xsl, if you want to use it you'll probably need to install
# libxslt (https://xmlsoft.org/XSLT/) version 1.1.0 or greater.
# - sets the ini files into the install directory instead than on cgi-bin
# - to add more domains just copy the cgi binary to the new domain
# cp "$PHP_BIN_DIR/php-cgi" "$NEW_CGI_BIN_DIR/php.cgi" and modifiy the .htaccess
#Script for a minimal PHP 5.3.x install with APC
#
#- Prompts for the domain to build for
#- PHP configure line contains only valid PHP5 options
#- Displays colourful status messages
#- Many build messages, which aren't helpful to most people, are now suppressed
#- Procedurised, making it cleaner and easier to follow
#
#The only things you may want to change in here are marked with "@todo"s
#
#Derived form the original PHP 5.3 install script at
#https://wiki.dreamhost.com/Installing_PHP5

MySql World Database as YAML fixture – OPENGIS.ch

Sat, 10 Oct 2009 00:00:00 +0200

For Symfony application I’m developing I needed all the Region separated by continent (7 continents model). I converted the MySql World Database (https://dev.mysql.com/doc/world-setup/en/world-setup.html) to a YAML NestedSet fixture file.
I just had to make 4 minor changes to it:
– rename the 3 continents that had region with the same name name (North America, South America, Antarctica)
– rename the Micronesia/Caribbean region to Micronesia-Caribbean.
thats’ all, enjoy the file Region.yml

Adapting doctrineexport.grt.lua to symfony standards – OPENGIS.ch

Thu, 17 Sep 2009 00:00:00 +0200

Using Mysql workbench to visually design a data model for a symfony application is pretty cool. Thanks to the guys of https://code.google.com/p/mysql-workbench-doctrine-plugin/ you can export the model to a YAML file ready for Doctrine.
the only problem I found using version 0.36 is that classes names are not in UpperCamelCase but in lowerCameCase and that if you have a table column that starts wit id (like idea) it gets cut to id (issue report: https://code.google.com/p/mysql-workbench-doctrine-plugin/issues/detail?id=15). so here my two modifications of the script to behave the way I want.
At the end of function buildTableName(s) add:

migrating wordpress from gengo to wpml – OPENGIS.ch

Sat, 15 Aug 2009 00:00:00 +0200

A client of mine used to have a multilingual blog using the Gengo plugin, which I consider by now unfortunatly dead. Fortunately, the guys at https://www.wpml.org did a great job creating a new plugin that works like a charm.
I did the migration from one to the other and I had no troubles (beside figuring out how to map gengo’s model to wpml). Further down are two SQL statements to check and update the posts language in wpml.
IMPORTANT: first disable gengo, then install wpml, then choose the default language and create the languages you had in geng. All your post will now be in the default language. you can check this with this SQL statement (for example using phpMyAdmin)

wordpress iphone app with wpml – OPENGIS.ch

Fri, 07 Aug 2009 00:00:00 +0200

I’ve a client using a wordpress multilingual blog with the wpml plugin (wpml.org/) and that wants to use the wordpress iphone app (iphone.wordpress.org). The app and the plugin work like a charm. the only problem is that in the app you can’t set the post language, hence you are (well by now were 🙂 ) able to post only using the default language.
I wrote a small PHP script to put in the root dir of your blog that updates the default language of the blog when called. so basically before using the iphone app you call the script using safari (https://domain.tdl/blog/set_post_lang.php?to=de) and then use the iphone application to post to your blog.
The script requires minimal configuration, you have to set the blog_id (if you have a single install, 0 should be ok, but you can find this by looking at the wp_options table in the DB) and an array of valid languages. Please note that the script uses no authentication methods, up to you to decide if you want to implement it (very easy actually for example with http_auth or with a key). I didn’t because the script does something very small and irrelevant from the security point of view.
And here the code, enjoy.

Activating error 503 from a shell script – OPENGIS.ch

Tue, 14 Jul 2009 00:00:00 +0200

During deployment of a new version of a website you might want to have your server returning an error 503 (temporarily unavailable). You can easily do this by pointing your web folder to a php page that contains this:

//server_down.php
header("HTTP/1.1 503 Service Unavailable");
echo "We are deploying a new version of NoSoapNoBubbles, the server is going to be down for a minute.";

if your webfolder is linked to another folder with a symlink (as I explained in my previous post symfony project on bluehost shared hosting) then you can just remove the link and add a new one pointing to the folder containing server_down.php. Remember to rename server_down.php index.php or to create an .htaccess file containing

Symfony project on (bluehost) shared hosting – OPENGIS.ch

Fri, 10 Jul 2009 00:00:00 +0200

So, I finally made it, set up a working Symfony project (with SVN) on my bluehost shared hosting plan, this tutorial should work for other hosters with minor changes. What I wanted was to be able of using my account as a development server for a small group of developers that would automatically show the last revision of the SVN repository. I pushed the solution further and created on the same account two more subdomains for the staging and production server. Please note that this last point is not the best thing to do, but I did it since we don’t know yet where we will put our production server when the application will really go live. As well, small budget apps could be set up this way if you really want 3 environments and you can’t afford a better hosting solution. Finally I installed Redmine so that we’ve a fully integrated development server with issues tracking, road-map, wiki, documentation and repository browsing.
Please note that bluehost uses something that looks like chroot jails, but read here for some concerns about symfony on shared hosts. Furthermore, i never use https in this tutorial, since I m using this as a test platform. As well this solution symlinks a www available folder to a folder outside public_html which could have some security implications. So remember security is as strong as the weakest link and YOU need to take care of it. Since setting up the whole thing it was a bit of an hassle, here how I did it (you need ssh acces to your account):

#BEFORE starting:
# - create an empty DB (using cpanel) and a DB user with full permissions on the db
# - create a mail user used to send out mails (quota can be set to 1Mb since you just need to send mails with it)
# - cd into the dir you want to install to. (for example /home/username/railsApps/redmine)
#
#AFTER (not mandatory):
# - create a subdomain (in cpanel) for redmine and link it to the public folder in redmine
# example:
# 	delete the default created folder
# 	rm -rf /home/username/public_html/redmine/
#	create symlink to the public folder

Crowdfunding: un soutien fiable pour les arcs de cercle dans QGIS – OPENGIS.ch

Mon, 01 Jan 0001 00:00:00 +0000

La vision: un traitement optimal des jeux de données avec des arcs de cercle

Les arcs de cercle sont un élément central dans le domaine de la géomatique. Une gestion précise et fiable de ces éléments est une condition essentielle pour travailler avec les données de la mensuration officielle. Une prise en charge complète des arcs de cercle dans le logiciel QGIS permettra d’exploiter cette application pour de nombreux nouveaux cas d’utilisation, tant pour la mise à jour des données de la mensuration officielle que pour le travail sur des jeux de données connexes, tels que la planification de l’utilisation du sol. QGIS permet déjà la saisie et l’enregistrement des arcs de cercle, mais ces derniers sont souvent perdus lors d’opérations comme l’intersection ou la fusion de géométries, qui entraîne un travail de post-traitement laborieux. Notre objectif est que QGIS prenne en charge ces opérations de manière fiable, efficace et sans erreur.
