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 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”
I have added two more styles to my QGIS Geometry Generator examples repository. The “Dynamic distance lines” style adds distance lines between all objects in your layer and a point you select in on your map. The “Points as tables” style shows a table based on the data in a points layer.
All my examples can be found on: https://gitlab.com/GIS-projects/qgis-geometry-generator-examples
I released a minor update to phpQGISrepository, my PHP script to create a QGIS plugin repository on your own server. In version 1.4.1 of the script the example plugin was updated and the links to the new code repository on GitLab were added. You can find all the info about this script on and download the latest version from GitLab: https://gitlab.com/GIS-projects/phpQGISrepository/.
Recently I released a minor update for PluginLoadTimes for QGIS. You can download the most recent version of this plugin from within QGIS, because it is available in the official QGIS Plugin Repository.
If QGIS takes long to start, it is probably because some of the plugins you installed take a long time to load at startup. This plugin shows the latest load time of each 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.
Sometimes a web service you use in your GIS application is offline and that results in a GIS application that doesn’t work as it should or doesn’t show the correct data. To avoid these problems you should have a local copy of the data of that web service. For a WFS service the data can be copied to a PostGIS database. This can be done using the command line utility ogr2ogr. This isn’t too hard but some people might be afraid to use the command line. So I wrote this guide about how to handle this from installation to automating the import procedure. Because this guide became pretty long I divided it up into 3 parts. Part 1 is about the installation of GDAL and ogr2ogr. Part 2 is about the use of ogr2ogr in a Windows batch file and part 3 is about automating the import procedure.
PART 1: installing GDAL and ogr2ogr
The utility ogr2ogr is part of the conversion library GDAL and is used to convert simple vector data from one file format to another. Since version 2.0 ogr2ogr also supports PostGIS data. The advantage of GDAL is that it’s available for many different operating systems and distro’s and that commands work similar on these different systems.
