Just posted a short how-to on turning Dutch NDFF biodiversity data 🌿📊 into species-richness heatmaps using QGIS and GDAL. Covers the basics: removing duplicates, filtering blurred records, dissolving per species, and rasterizing.
Just updated my 'Species Distribution Modeling in GRASS' reader 📘. Right in time for our upcoming module for first-year students in Aarde, data analyse en visualisatie at #HASgreenacademy 😅
Just “discovered” the Merged Features renderer. What a neat, handy feature! Kudos to whoever came up with that one. And yes, it’s been around for quite a while already, since around 2021, I believe 😊.
I would like to wish you all the best for 2026. Let's focus on the positive, as hard as that sometimes may seem, and work together towards some more happiness!
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.
🤟 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

A close-up of a dragonfly (Common Darter) perched on a broken bamboo stick, with its wings and body against a blurred, colorful background of red, green, and blue hues. Captured using a Fuji XT20 and Fujinon XF 100-400mm lens and processed using one of the best RAW editors, #Darktable .
A white crab spider (Misumena vatia) with red markings is camouflaged on a vibrant pink flower, near its bright yellow center, against a soft green background. Taken with #FujiXT20 + #FUJINON XF 100-400mm with NISI close-up lens. Edited in #darktable #FOSS

The western rock nuthatch (Sitta neumayer) has built its nest on a wall of the Roman Agora in Delphi, perfectly visible to the passing crowds of tourists just a few meters away. It didn’t seem to mind the attention. #darktable #fujifilm #foss
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
Interoperable Europe Portal
The Interoperable Europe Portal is the European Union’s platform for promoting and supporting interoperability, collaboration, and knowledge sharing across public administrations, businesses, and citizens. It acts as a one-stop shop for discovering, sharing, and reusing IT solutions and good practices.

Always on the hunt for the ideal note-taking app. 🧠 I tried #Logseq , and while I loved the logbook, I prefer to organize my notes in a tree-like hierarchy. It helps me to keep an overview. I therefore switched to TriliumNext ( https://github.com/triliumnext ). The option to place notes as
I have been playing with the QGIS model designer a bit more. This time, to create a model that I can use to quickly compare how two raster layers by plotting their values in a scatter plot. https://ecodiv.earth/post/raster_scatterplot/ . #QGIS #FOSS #osgeo #datavisualization
I am in the process of moving my shared pictures from one of the big tech platforms to my own hosted #piwigo instance. Together with #Digikam , which I use to manage my photos, it works like a charm 😃. FOSS rocks! #foss #darktable #photography https://piwigo.org/
Playing with the #NiSi 77mm close up lens on my #fujifilmXT30II. The picture isn't very sharp, those were tiny droplets, but I still like the overall result. #fujifilm #darktable #foss
Ever needed to reuse the same raster extent & resolution across multiple QGIS tasks? My latest blog post shows how the Raster Layer Properties function can automatically grab all those details from a reference layer. A good way to make your workflows more consistent and error-proof.
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
