A hydraulic engineer by training, Nicolas Godet has been working at ISL Ingénierie for just over seven years and holds the position of hydraulic project manager (flood risk, hydraulic structure safety), deputy director of the Saint-Jean-de-Luz facility, and QGIS (and GIS in general) advisor.

He discusses the implementation of QDT and the associated methodology for deploying QGIS across ISL’s IT infrastructure.

What are the objectives of the collaboration?

Before I took charge of deploying QGIS at ISL, it was a bit of a mess: no one had the same version, the same plugins, or the same practices.
Following the switch to QGIS3, there was a desire to standardize the QGIS fleet at ISL to have the same version, the same plugin base, and preconfigured profiles.

An initial, semi-homemade solution was implemented in 2022, but it proved difficult to maintain.

At the end of 2024, with a budget allocated, we decided to seek assistance from Oslandia to professionalize our QGIS deployment so that every employee would be using the same version:

• facilitate project sharing within ISL and with our clients,
• have a common and up-to-date plugin base,
• benefit from advanced pre-configuration of user profiles.

The ultimate goal was to be able to update QGIS without disrupting all the configurations.

What challenges does this project address?

The challenge was to be able to keep up with developments in QGIS while retaining profile configurations. Having attended a few presentations (QGIS Days), I had heard about QDT. After preliminary discussions with Oslandia (and in particular with Julien Moura), we agreed to go ahead with customized training. This customized training allowed us to adapt the content to our needs.

How did the collaboration with Oslandia go?

The Oslandia teams are attentive, adapt to our needs, which are not always simple, and were able to offer us tailor-made training.

We decided to have four half-days spread out over several weeks, allowing us to cover the theory and a few examples during the half-day, then work on our own and come back to the next session with questions and ask for more in-depth coverage of certain points rather than others.
There’s not much else to add except that it went very well!

Since this training, ISL has been able to invest in QDT.

Oslandia is the main partner of OPENGIS.ch around QField. We are proud today to forward the announcement of the new QField release 3.4 “Ebo”.

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:

• Alert user when inside an area polygon;
• Alert user when outside all defined area polygons and
• Inform the user when entering and leaving an area polygons.

In addition to being alerted or informed, users can also prevent digitizing of features when being alerted by the first or second behaviour. The configuration of this functionality is done in QGIS using QFieldSync.

Pro tip: geofencing settings are embedded within projects, which means it is easy to deploy these constraints to a team of field workers through QFieldCloud. Thanks Terrex Seismic for sponsoring this functionality.

QField now offers users access to a brand new processing toolbox containing over a dozen algorithms for manipulating digitized geometries directly in the field. As with many parts of QField, this feature relies on QGIS’ core library, namely its processing framework and the numerous, well-maintained algorithms it comes with.

The algorithms exposed in QField unlock many useful functionalities for refining geometries, including orthogonalization, smoothing, buffering, rotation, affine transformation, etc. As users configure algorithms’ parameters, a grey preview of the output will be visible as an overlay on top of the map canvas.

To reach the processing toolbox in QField, select one or more features by long-pressing on them in the features list, open the 3-dot menu and click on the process selected feature(s) action. Are you excited about this one? Send your thanks to the National Land Survey of Finland, who’s support made this a reality.

QField’s camera has gained support for customized ratio and resolution of photos, as well as the ability to stamp details – date and time as well as location details – onto captured photos. In fact, QField’s own camera has received so much attention in the last few releases that it was decided to make it the default one. On supported platforms, users can switch to their OS camera by disabling the native camera option found at the bottom of the QField settings’ general tab.

Wait, there’s more

There are plenty more improvements packed into this release from project variables editing using a revamped variables editor through to integration of QField documentation help in the search bar and the ability to search cloud project lists. Read the full 3.4 changelog to know more, and enjoy the release!
