A gauges style for QGIS

Gauges style in QGIS

I added a new “Gauges” style for QGIS to my GitLab repository that contains some of my use cases of Geometry Generators.

All info on this new QGIS style, including example files, can be found on https://gitlab.com/GIS-projects/qgis-geometry-generator-examples/tree/master/QML-files/gauges

You can download the entire repository with all my Geometry Generator examples at once: https://gitlab.com/GIS-projects/qgis-geometry-generator-examples/-/archive/master/qgis-geometry-generator-examples-master.zip

Version 2.0.1 of ZoomToBelgium for QGIS released

Last week I released a new version of my QGIS plugin ZoomToBelgium. This plugin helps you to zoom to one of the administrative boundaries in Belgium with one click on a button. In the front end of the plugin you probably won’t notice many differences with version 1.x of the plugin, but in the back end the plugin was updated to make it easier to maintain. This new version is only available for QGIS 3.x. QGIS 2 is no longer supported.

Convert a points layer to a polygons layer in QGIS without using plugins

In QGIS it’s possible to convert a points layer to a polygons layer in just a few steps. To do so there are some minimum requirements for the points layer, because QGIS has to know which points should be grouped to a polygon and in which order these points must form a polygon. To illustrate this I have created a test layer with 7 points. I added two new fields: “polygon” and “order”. The field “polygon” indicates which points have to form a polygon together. In this example the result should be two polygons (1 & 2). The field “order” indicates in which order the points should be connected to form a polygon. In this example the result will be a triangle and a quadrangle (quadrilateral).

How to autonumber a field in QGIS

To autonumber a field to give it a unique number, is something very common in databases like for example PostgreSQL with a Serial field type. But for other kinds of data sources this too can be very handy. Below I give an example of how you can do this in QGIS. It is a way to autonumber in QGIS that can be used for all kinds of vector data sources, so it’s also usable for for example shapefiles.

List of webservices with data for Belgium now also in English and French

Since a couple of years I maintain 4 web pages with lists of WMS, WFS, WMTS and XYZ tile services that contain data for Belgium. When I recently attended the FOSS4G Belgium conference in Brussels, it became clear these web pages are pretty popular with the Dutch speaking GIS folks at the conference. The WMS page was even on one of the slides for the keynote by OGC president Bart De Lathouwer.
