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. 🤔

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.

I just tried the latest Trilium Notes release with its redesigned interface.
It took me about 15 minutes to adjust, and now I’m sold.

Same powerful functionality, but with a calmer, cleaner look.
I suspect it’ll be much easier for new users to find their way through the many options.

Oh, for those who don't know Trilium, check it out (https://triliumnotes.org/). It is a great note-taking app / personal knowledge base app.

Great job! 🙌

🤟 Love the new option to change the note color directly from the tree context menu in #TriliumNext #trilium #triliumNotes 🎉 New in version 0.1 https://github.com/TriliumNext/Trilium/releases/tag/v0.100.0

It was great to connect with the open source geo community at the [FOSS4G.NL 2025](https://foss4g.nl/). The event highlighted innovative open-source projects and collaborations.

I presented on [GRASS](https://grass.osgeo.org/) in education and research, outlining its current state and sharing examples of how I use it in my classes and research at the HAS green academy. [View slides](https://ecodiv.earth/share/foss4gnl2025/#/title-slide)

I just stumbled across the site 'Interoperable Europe.' It seems worth looking into (https://interoperable-europe.ec.europa.eu/). It is an initiative of the European Commission to stimulate public sector interoperability.

There isn't much (yet) on Geo-spatial tools, but at least #grassgis is there :-). Time for #osgeo / #foss apps to be added?

Renamed a mapset in my GRASS database, and all space-time datasets in that mapset became inaccessible. Something to do with how the temporal database stores references to these space-time datasets.

Mildly annoyed at my past self for not planning mapset names better, but mostly curious now.

Time to explore how GRASS handles temporal metadata under the hood 🕵️‍♂️. A bit nerdy perhaps, but I did find an admittedly hacky solution. https://ecodiv.earth/post/Fix_STRDS_references/ #grassgis #foss #LearnByDoing

We just wrapped up the first 2.5 years of the Save The Tiger project: https://savethetiger.nl/research/what-we-did-so-far/
Next week, a new group of #HASgreenacademy students heads to Nepal for #fieldwork in the beautiful Chitwan and Bardia NP's. Wish I could join them #savethetiger #Nepal #ecology #natureconservation #vegetationsurvey

I am a happy user of #logseq. For Linux, it is available as #appimage which I usually install using #AppImageLauncher.

Unfortunately, after upgrading Ubuntu, Logseq couldn't be launched anymore in the usual way. After some searching online, I found a workaround.

You need to locate and open the desktop file and add `--no-sandbox %u` to the end of the line starting with `Exec`.

Not an ideal solution, but it'll have to do for now. See this post for more details. https://ecodiv.earth/post/logseq_desktop_integration/

Check out the new global tree canopy height map by Meta and the World Resources Institute (https://sustainability.fb.com/blog/2024/04/22/using-artificial-intelligence-to-map-the-earths-forests/). See https://ecodiv.earth/post/treeheightmap/ for a description of how to import the map for your area of interest in #grassgis and get a map with acquisition dates.

Be careful when using the data for your analysis, though. Some patterns clearly reflect differences in the dates of acquisition of the source imagery, rather than actual differences on the ground.

The autumn-version of the American Botanical Society's Plant Science Bulletin has just been published, https://lnkd.in/eQNgXUhA (page 233), with a nice :thinkhappy: review of our (Ib Friis, Sebsebe Demissew Odile Weber) book The Western Woodlands of Ethiopia (https://lnkd.in/dS_y92UA). #vegetationscience #botany #biogeography #ethiopia

GEO Experience Dag

Discover how students of #HAS green academy are working on practical solutions for current and future spatial challenges during the Geo Experience. This is the event where the workfield, students and research in the geo-spatial domain come together to exchange the latest insights and experiences. #geoexperience #HASgreenacademy #geospatial
