Finished teaching #QGIS for #Groundwater Applications to the #ErasmusMundus 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 #IHEDelft in 6 months!

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

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

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. -
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.

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.

🌳 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.

Interesting to see the distance between Maplands (home of
@qgis) and Geosppytiallia (home of @movingpandas) in #MapOfGithub https://anvaka.github.io/map-of-github/#11.91/27.53081/20.1991Why are Lidaria and Carto3Dica in between?

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.

New release 🎉
#Trajectools 2.3 brings trajectory generalization, cleaning, and smoothing algorithms to #QGIS
Inspired by #SDSL2024, I've written up the first Trajectools tutorial on #trajectory data preprocessing

✨ We're proud to announce #Trajectools for #QGIS version 2.2 release today ✨
This release makes sure that Trajectools can be more easily installed since #MovingPandas is pip-installable on most systems and the #scikitmobility and #gtfsfunctions dependencies are now optional

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, #movingpandas, and #scikitmobility) that hopefully will catch people's eyes and make them curious

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.

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
