Caitlin Haedrich shared her dissertation defense recording online: "Integration of GRASS and Jupyter...was one of the coolest things I got to be a part of...It feels very special to have someone else use your code."

GRASS tool highlight: i.segment does object-based image segmentation using region growing with merging or mean shift. Supports hierarchical segmentation: run at threshold=0.02, feed the output as seeds into the next pass at 0.08, 0.20, 0.40. As the threshold increases, more spectrally similar neighbors merge into fewer, larger segments.

Just published a tutorial about using GRASS for a viewshed workflow that employs an observer-relevant surface to selectively represent obstructions that effectively block line of sight at pedestrian height. This derived layer is then used to perform a cumulative viewshed analysis. Check it out here: https://ecodiv.earth/post/intervisibility/ #grassgis #osgeo #ahn #viewshed @grassgis
Just updated my 'Species Distribution Modeling in GRASS' reader 📘. Right in time for our upcoming module for my 'Earth, data-analysis and visualization students at #HASgreenacademy 😅
Mostly small changes about the organization of results. The least exciting part of modeling, but it can absolutely mess up your workflow if not done right. Hopefully this lands before students learn that the hard way. 🤔

Es geht los: #fossgis2026 in Göttingen!
Wir sind mit unserem Team von @mundialis da, besucht uns an unserem Stand!
Und hier unsere Vorträge:
Coffee Talk: Geomorphometry with GRASS with Corey White (Center for Geospatial Analytics @ NC State University; GRASS Core Development Team Member) will discuss GRASS as a high-performance, extensible #geospatial engine for #geomorphometry. Examples include post–hurricane analysis, DEM fusion & terrain uncertainty. Also: Python/R/Jupyter integration + an open add-on ecosystem for sharing methods.

Der @FOSSGISeV war ursprünglich die
GRASS-Anwendervereinigung e.V. (GAV) @grassgis .
Die Gründungsversammlung zur GAV fand am 15.04.2000 statt, die Eintragung als gemeinnütziger Verein erfolgte am 18.01.2001.
Im Jahr 2008 nannte sich der Verein in FOSSGIS e.V. um.
In diesem Jahr feiert der #FOSSGIS-Verein das #25Jubiläum.
Ziel: die wachsende deutschsprachige Nutzer- und Entwicklergemeinschaft von GRASS GIS vernetzen, die Weiterentwicklung der Software aktiv
zu fördern.
