    🎉We&#39;ve just passed 50% of the crowdfunding goal for bringing native #hydrology tools in #qgis. Thanks for all donations so far🙏🏼 If you rely on hydrological workflows in QGIS or simply want to strengthen #OpenSource #gis, please consider supporting the effort so these tools land in QGIS 4.4. 👉 Full details &amp; donation: https://www.qwast-gis.com/l/crowdfunding-native-qgis-tools-for-hydrology/ #OSGeo #FOSS4G @northroadgeo@fosstodon.org

    #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. 🎥 Video: https://videos.qwast-gis.co...

    I just passed 35K subscribers on my YouTube channel and I&amp;#39;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. ▶️ QwastTube: https://videos.qwast-gis.com/ ▶️ YouTube (if you still use it): https://www.youtube.com/@HansvanderKwast #FOSS4G #OpenSource #PeerTube #DigitalSovereignty #QGIS #GIS #WebODM #PCRaster #RemoteSensing

    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. ▶️ QwastTube: https://videos.qwast-gis.com/w/iUHsR4ceNzcP3d1B287sJ9 #QGIS #GeoAI #GenAI #SpatialPlanning #GIS

    #30DayMapChallenge Day 5: Earth🌍 I mapped gas fields, mines &amp;amp; earthquakes in the Netherlands. #Groningen’s gas extraction and #Limburg’s mining caused seismic risks, which js now a political issue around damage &amp;amp; compensation. I made this while teaching #QGIS &amp;amp; @merginmaps in Leek (Groningen) for my company #QWAST, hired by #Fervent &amp;amp; #Geo2Meet. The course is part of a reskilling project for GIS jobs. #GIS
