I have a GitLab repository where I have a lot of example usage of QGIS Geometry Generators. I added a new example to that repository.

A list of OGC API Feature Services with data for Belgium
Geospatial web services like WMS, WMTS, WFS and XYZ tile layers are used a lot by GIS professionals. In the past I made different webpages with lists of these different types of services that contain data for Belgium. Since a couple of years the Open Geospatial Consortium (OGC) has been busy creating new standards to replace these older types of web services. One of those new standards is OGC API Features.
Recently I created a new website to list OGC API Features services with data in Belgium. It can be found on https://features.michelstuyts.be.
If you know any OGC API Features services with data in Belgium that are not listed on that website, please let me know and I’ll add them. Currently I have only found services with data from Flanders.
All my lists:
Two new QGIS Geometry Generator examples
I have a GitLab repository where I have a lot of example usage of QGIS Geometry Generators. I added two new examples to that repository.
Bevelled edge
The first example adds a bevelled edge to a polygon. For the example I chose to add the bevel on the inside of the polygon.
#30DayMapChallenge: My maps from the 2021 challenge
I participated this year again in the 30 Day Map Challenge (Github) organized by Topi Tjukanov. Here are the maps I posted on Twitter, LinkedIn, Instagram and Mastodon for this challenge.
How to get data from the Mapillary API v4 using Python
A while ago I wrote a script to get data from the Mapillary API v3 and that was pretty easy to do so. But in the mean time v3 of their API was discontinued, so I had to rewrite my script to use v4 of the API, but it took me a while to figure out how to talk to the v4 API using Python.
Below you can find a simple example of how to get info on available images around a certain longitude and latitude. Of course you can incorporate this concept into a larger script to get data from multiple points, that can for example be stored in a database. But for this example we’ll just request info on available Mapillary imagery for one set of coordinates and show the information.

Because coordinates are often stored with too much detail to be useful, I made some maps to show what each detail level in WGS84 (EPSG:4326) means.
