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, Read more…
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 Read more…

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 Read more…
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 Read more…
