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.Continue reading “How to autonumber a field in QGIS”
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.Continue reading “List of webservices with data for Belgium now also in English and French”
I recently moved the demo repository of phpQGISrepository (https://plugins.stuyts.xyz/) to a new webhost and since then it didn’t work anymore in QGIS 2.18. In QGIS 3.x and in all webbrowsers it still worked just fine, but in QGIS 2.18 it gave a 400 error (Bad Request).Continue reading “A simple fix if phpQGISrepository doesn’t work in QGIS 2.18”
If QGIS takes long to start, it is probably because some of the plugins you installed take a long time to load at startup. Plugin Load Times shows the latest load time of each QGIS plugin (QGIS startup, plugin installation,…). It does not give you information about the speed of plugins when they are used. With the information provided by this plugin you can easily decide which plugins to disable, to make QGIS start faster.
A couple of weeks ago I released version 3.0 of Plugin Load Times. Since QGIS 3.4 is the new LTR version, this version of the plugin will only be available for QGIS 3.x.Continue reading “Plugin Load Times v3.0 for QGIS released”
Here you can find a series of building footprint maps of 10 different Flemish cities. Can you guess which map is which Flemish city? The solutions are on page 2 of this quiz.Continue reading “Quiz: Recognize 10 Flemish cities based on their building footprint map”
I created a QGIS style that will draw a curved line between a point and the closest other point in that same layer. This way you can visualize nearest neighbours and also see clusters of points.Continue reading “Visualize nearest neighbours with Geometry Generator in QGIS”
