#qgis — Public Fediverse posts

Live and recent posts from across the Fediverse tagged #qgis, aggregated by home.social.

  1. Finished teaching for Applications to the GroundWatCh MSc students at IST in Lisbon! Despite very hot days in classrooms without AC, the group worked hard and produced great groundwater and surface water maps.

    Today, the students received their official QGIS certificates.

    Great closing session with @timlinux, presenting on QGIS behind the scenes. Looking forward to seeing the students again at in 6 months!

  2. 🚀 The new edition of the book is almost available. It’s not open access, but I’m glad to see a strong shift toward tools like , , , and Python/R packages. Happy I could contribute to this through my chapter on QGIS and PCRaster!

  3. I’ve published a new video showing how the AI Edit plugin by #TerraLab can be used to visualise spatial planning scenarios in #QGIS. ▶️ QwastTube: videos.qwast-gis.com/w/iUHsR4ceNz... ▶️ YouTube: youtu.be/8qiNQVCGlsQ #GeoAI #GenAI #SpatialPlanning #GIS #NanoBanana

  4. Spotted this while exploring my #wardriving results in #qgis.
    It appears that there's a house with a JuanCloud wireless NVR running on channel 13.
    This is somewhat interesting as channels 12 and 13 are only allowed in North America at very low radiated power limits (14 is outright banned).
    I would guess that this person is running the device illegally, likely without even realizing it.

  5. Got fed up with #wigle's web interface and started loading my #wardriving records into #qgis instead.

    Overly complicated and massively overkill?

    Yes... but it is working.

  6. Welp, my #mapping attempt at a "Total Value Per Acre" map of #BloomingtonIN failed, but the mess looks pretty.

    I believe outside of the core city blocks, too many parcels got joined during a "dissolve" phase, resulting in these mega areas of the same color which shouldn't be there.

    It's an interesting analysis to run when considering annexation to check if the proposed additions would contribute more or less on average than existing city blocks.

  7. 🌳 Random Forests and Living Trees

    English translation of my earlier article on applying satellite imagery and machine learning to map urban land cover.

    What started as a local research project in Kryvyi Rih turned into something much larger — the results sparked a heated discussion among residents, officials, and industry representatives about the real condition of green buffers around large industrial sites.

    The methodology developed during that work is still being used today — adapted for new environmental and urban projects.

  9. Just wrapped up teaching for Hydrological Applications to MSc students at @tudresden's beautiful campus 🍁.

    Students completed 7 lessons based on the book I co-authored with @geomenke, earned QGIS certificates, and battled daily Kahoot quizzes for swag and a signed copy of the book! Open source GIS powering future water experts! 💧

  10. Ideas for YouTube

    Through May 30, 2025 novaTopFlex is an identity, a community, and an ethical channel on YouTube, all focusing predominantly on advocacy for open contributions and the elimination of closed contributions. Although the topics of interest may vary substantially through the three identities, the ideologies remain fairly similar. novaTopFlex novaTopFlex is the technological identity, acting as the main identity for the novaTop personality. novaTopFlex Examples Examples of content containing […]

  11. I've had smoother releases 🙃

    But hey, 0.21 is here github.com/movingpandas/moving

    Make sure to update if you want to use the new plugin version which will be released soon 🆙

  12. Interesting to see the distance between Maplands (home of
    @qgis) and Geosppytiallia (home of @movingpandas) in anvaka.github.io/map-of-github

    Why are Lidaria and Carto3Dica in between?

    It's all (Landia) 😜

  13. These are the Voronoi polygons of the intersections in #BloomingtonIN

    If you wanted to assign every crash to an intersection, creating voronoi polygons and then counting the crashes in each polygon would be one way to do it, as each polygon represents exactly one intersection.

    Works best in denser areas. In sparser networks, you increase the likelihood that the crash was not close by, like with the larger polygons in the corners here.

  16. Thank you all for your feedback :ablobcathappypaws:

    Quite happy with v2 ...

    Got rid of all the window decorations, tried to better align the elements, and couldn't resist to add some more logos (#qgis, , and ) that hopefully will catch people's eyes and make them curious

  17. En la #qgiscamp2024 (previa a las #siglibre2024) hemos llegado al momento «un edificio es un punto», a lo que yo añado: de masa despreciable y carga eléctrica neutra en un vacío sin rozamiento.

  19. Thanks to @BNHRdotXYZ for leading last nights' #Wemap session on @qgis.

    It was a fun getting your feet wet on #GIS, and was an excellent overview of what's possible with #QGIS and #OpenData, like #OpenStreetMap
