Volunteering for the campaign of #GLPvdA during the last municipal elections in Rotterdam inspired me to try a small pilot for planning and monitoring canvassing with #QGIS and @merginmaps.
In my new video, I show how to set up a similar workflow: simple, practical, and fully #opensource.▶️Watch on QwastTube: https://videos.qwast-gis.com/w/je8KqK2BpNyNREiavxidYB

confused about #postgis ST_NPoints with polygons, because a triangle apparently has 4 points.
SELECT ST_NPoints(ST_GeomFromText('POLYGON ((0 0, 0 1, 1 0, 0 0 ))'));
From a technical point it makes sense, but it is also quite unintuitive, because normal people on the street would definitely say a triangle has 3 points ...

Just open-sourced QGIS Style Manager v0.3 — export & import layer styles (QML) with project-based organization.
v1 was a local QGIS 3.x tool. Migrating to QGIS 4.0 / Qt6 broke a few things — enums, return types, deprecated APIs — so I fixed it up and made it public.
✅ Compatible with QGIS 4.0 (Qt6)
✅ Auto-organizes styles into ProjectName/ subfolders
✅ Configurable keyboard shortcuts
✅ i18n support (EN + UK) -

How did Calgary respond to the wet summer of 2025?
Here’s the median summer NDVI map derived from Sentinel-2 imagery.
You can clearly see the Bow River corridor, Nose Hill Park, and the contrast between established tree-rich communities and newer developments.Full analysis here:

I'm busy finishing my presentation about my websites on geospatial webservices with data for Belgium. If you want to come and hear me talk about what that is and how and why I make these websites, you can hear me tell me all about it at FOSS4G Belgium this thursday in Brussels at 15h50 in the "Qleur Café" room. You can still get tickets on https://www.foss4g.be.

Vorige week waren we weer met veel :qgis: leden bij de #FOSS4GNL, georganiseerd door @osgeonl!
In het nieuwe Omnia-gebouw op Wageningen Campus kwamen we samen met de NL open geo-community. Het programma stond vol met interessante workshops en inspirerende presentaties.
⛺️ Voor onze leden was er ook weer een supergezellige QGIS Camping!

Vandaag hadden we een fantastische #QGISNL Gebruikersdag over #remotesensing bij Cobra Groeninzicht in Vianen (NB), georganiseerd door Dirk Voets en @hansakwast. Veel kennis uitgewisseld over de mogelijkheden van #QGIS en andere #opensource software voor analyse van satellietbeelden, drone beelden, luchtfoto's en point clouds! 🚀📡 :qgis: @osgeonl #foss4g
