I just passed 35K subscribers on my YouTube channel and I'm grateful for everyone following my open‑source geo work.
But for those who prefer to avoid big tech: my videos are also published on #QwastTube, my own #PeerTube instance.

#WebODM has officially split from #OpenDroneMap.
Official announcement from WebODM https://webodm.org/blog/announcement/
I made a short video showing the full workflow:
💻 Install WebODM with the new native installers
📸 import drone images
⚙️ process (orthomosaic, DSM, point cloud, 3D model)
🖼️ view in 2D/3D
⬇️ download results
🗺️ open in QGIS
If you want a user‑friendly, #opensource alternative to proprietary photogrammetry tools, WebODM is highly recommended.

I’ve published a new video showing how the AI Edit plugin by #TerraLab can be used to visualise spatial planning scenarios in #QGIS.
From replacing an airport to simulating floods, adding green roofs, reopening canals, or generating a Dutch polder, it’s all there, with impressive visual results.

Na 9 jaar keert #FOSS4GNL terug naar Groningen, waar het in 2017 begon.
Twee dagen vol #opensource geo: hands‑on workshops + een dag presentaties voor developers, toepassers, beheerders en beleidsmakers.
Samen met de @Jantina_Tammes_School@social.edu.nl bouwen @osgeonl@fosstodon.org en @qgisnl@mapstodon.space aan het programma & side‑events. Ideeën en helpende handen zijn welkom!
New open course at @gisocw@fosstodon.org! Learn collecting ground truth in the field with @merginmaps@fosstodon.org, #AI-assisted #segmentation of ground truth polygons with the AI Segmentation plugin by #TerraLab and the full workflow from downloading #Sentinel-2 data, Random Forest classification & accuracy assessment using the Semi-Automatic Classification plugin in #QGIS.
📢 Mergin Maps tutorial videos are now on #PeerTube!
If you use @merginmaps@fosstodon.org, the #opensource, field data collection tool built on #QGIS, you can now watch the video tutorials on #QwastTube:

#QGIS #OpenSourceGIS #CommunityBuilding #QGISOpenDay
#FOSS4GNL earlier this week in Wageningen was very inspiring. Great to see what the Dutch #opensource #geospatial community is doing. Nice to contribute with presentations and workshops. Read my blog for an impression: https://www.qwast-gis.com/l/foss4gnl-at-wageningen-campus/
@osgeonl@fosstodon.org @qgisnl@mapstodon.space #qgis @merginmaps@fosstodon.org
@osgeonl@fosstodon.org organiseert op 17 april een beginnersdag voor iedereen die met #opensource #geo wil starten. Ik geef daar een workshop over @merginmaps@fosstodon.org: in #QGIS een surveyproject opzetten en daarna buiten karteren met je telefoon. 📱🗺
Kom je ook? Programma en registratie: https://osgeo.nl/0_events/beginnersdag/
🚀 The new QGIS Certification Programme Website is live! Now it's easier to find certified training courses:
🗺 Use an interactive map to find certified training providers.
📅 Check out upcoming courses offering official QGIS certification.
🙏 Big thanks to Lova Andriarimalala, @timlinux@fosstodon.org & others for making this possible!
#30DayMapChallenge Day 5: Earth🌍
I mapped gas fields, mines & earthquakes in the Netherlands. #Groningen’s gas extraction and #Limburg’s mining caused seismic risks, which js now a political issue around damage & compensation. I made this while teaching #QGIS & @merginmaps@fosstodon.org in Leek (Groningen) for my company #QWAST, hired by #Fervent & #Geo2Meet. The course is part of a reskilling project for GIS jobs. #GIS
🚀 Today, I'm running a workshop on #PointCloud Processing in #QGIS at #FOSS4GEurope 2025 in #Mostar! We'll dive into:
🔹️ Downloading & preprocessing data
🔹️ Creating DSMs with interpolation
🔹️ 3D visualization & styling
🔹️ Elevation profiles & filtering
🔹️ Automation with #PDAL Wrench
🔹️ Editing point clouds
💻 Can’t join in person? Free access at @gisocw@fosstodon.org

🎥 New video demonstrating the #QGIS Resources Hub portal and QGIS Hub plugin: https://youtu.be/79yFgVLvuZM
Improvements were made during the QGIS Contributor Meeting last week in Norrköping, Sweden. Thanks to @xpirix@mastodon.social, @ismailsunni@fosstodon.org & Ronit Jadhav!
Looking forward to see more contributions from the QGIS community to the hub! Styles, projects, models, layer files, Map Gallery & Processing Scripts—all making the hub a richer resource for geospatial innovation! 🚀
Taught #QGIS for groundwater applications to #ErasmusMundus #GroundwatCH MSc students last week at Instituto Superior Técnico in Lisbon. With inspiring guest lectures from @timlinux@fosstodon.org & alumna Namrata Karki. Students received the official QGIS certificate. #IHEDelft
Leaving Norrköping, Sweden, after an amazing #QGISUC2025! Some contributions during the Contributor Meeting:
🗺️ Added Map Gallery & Processing Scripts to #QGIS Hub web page (https://hub.qgis.org/)
🛠️ Fixed QGIS Hub plugin bugs w/ @ismailsunni@fosstodon.org @xpirix@mastodon.social & Ronit Jadhav
📢 Created geofenced news feed for FOSS4GNL w/ @terglobo@mastodon.social
📜 Reviewed QGIS Certification applications w/ @geomenke@fosstodon.org
🙌 This community is incredible! See you at @foss4geurope@fosstodon.org & next year in Switzerland!
🎙Last Saturday, I had a great chat with Safae Aala on the I.Talk podcast about my 25-year GIS journey. We covered QGIS, open source, education & innovation.
