Converts simple #SVG icons into #GRASSGIS 's #native #vector #symbol #format, the small text grammar read by d.vect icon= (VERSION/BOX/POLYGON/RING/STRING/LINE/ARC). #GRASS has no SVG symbol support at all, so this fills that gap for anyone who wants to render SVG-designed icons as GRASS point/centroid symbols. -

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. 🤔

Mostly small changes about the organization of data and results. The least exciting part of modeling, I know, but it can absolutely mess up your workflow if not done right. Hopefully this lands before students learn that the hard way. 🤔

I've created two new GRASS addons to facilitate the exchange of raster styles between QGIS and GRASS: r.colors.qml and `r.colors.toqml`.
🎨 r.colors.qml: Apply QGIS QML style files directly to your GRASS rasters.
🔄 r.colors.toqml: Export GRASS color tables and categories back to QML for use in QGIS.Read the full post here! 👇

#30daymapchallenge Day 17: A new tool
Helsinki enjoyed a grand total of 12 minutes of sunshine in November (1.–13.11). No better time to remember that yes, the sun does still exists.This map shows Helsinki's shadiest / sunniest places in June. New tool? #GRASSGIS solar irradiance model.

🌊 Modeling a potential dam breach — and how panic spread beyond the real watershed
This project assessed the potential consequences of a dam failure at a mine-water impoundment in the Svystunova Gully.
🔹 Reconstructed the original pre-impoundment terrain from archival topographic maps.
🔹 Used Sentinel-based land-cover classification to assign variable Manning’s roughness coefficients.
🔹 Built a modern DEM including the dam structure and current flooded zone.
🔹 Simulated dam-break flood dynamics in GRASS GIS — frame by frame.
🔹 Produced a video visualization to help local communities understand real risks (and ignore fake ones).
🔹 The results were later featured in regional media and used in discussions about mine-water safety.🎥 Watch the short video visualization:
