Writing a feature-based processing algorithm at the example of M-value interpolation

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 Read more…

A New Trick up QField’s Sleeve: Animated Maps

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 Read more…

High Efficiency with Buffered Transactional Editing in QGIS

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 Read more…

QField collected data crucial in disaster relief after Tonga’s volcanic eruption

For once, it’s not an app from the Silicon Valley, but from Laax in the Swiss Alps that made the news. 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.
