For years, QGIS users have relied on external toolsets from processing providers such as SAGA, GRASS, WhiteboxTools and PCRaster for hydrological analysis. These tools are powerful, but they also introduce challenges: installation issues, inconsistencies across operating systems and versions, and workflows that break when dependencies change....
This morning, the PCRaster Tools plugin for QGIS officially passed 100,000 downloads. For a project that began as a modest prototype, this milestone marks a major achievement! It shows how deeply practitioners value robust, transparent, and reproducible workflows, and how PCRaster Tools has become a trusted foundation for those workflows.
Nine years ago, we held the very first FOSS4GNL in Groningen. This year, we returned, and it felt like coming home. Thanks to the generous support of the Jantina Tammes School of Digital Society, Technology and AI at the University of Groningen, we enjoyed two inspiring days in their beautiful venues.
It's always a joy to arrive at FOSS4G Europe and immediately be surrounded by familiar faces: people you've worked with, collaborated with, debated with, or shared a drink with over the years. But what makes this community truly special is that every edition also brings new people, new ideas, and new energy. This year in Timișoara, Romania, was no...
I'm excited to share a new collaboration that aligns perfectly with the mission of QWAST‑GIS: empowering professionals, organizations, and students with accessible, high‑quality open‑source GIS knowledge.
Do you enjoy my YouTube channel but also care about digital sovereignty and privacy? Today, I'm excited to launch QwastTube, a fediverse alternative to my YouTube channel, built for people who value open ecosystems, user autonomy, and community‑driven platforms. These principles are at the heart of what we do at QWAST.
The Netherlands is striving to become greener, but where do you start if you don't know exactly how much greenery is already in place? A newly updated Base Map of Green and Paved Surfaces in the Climate Impact Atlas (KlimaatEffectAtlas) now provides the answer. With a resolution of just 25 centimeters, the map shows in remarkable detail how...
This year I had the honor of being recognized with the Spatial Impact Award 2025 by Atlas. It is both humbling and energizing to see my work in open-source GIS and water resources acknowledged in this way. For me, spatial analysis has always been more than technical workflows, it is about empowering people to understand their environment and...
Taking part in the #30DayMapChallenge is always a test of creativity and endurance, but November 2025 proved to be especially demanding. The month began with the grandeur of Carmina Burana concerts at MECC Maastricht, performed with Brabantkoor (I was a tenor in the choir) and the Jussen Brothers, and quickly unfolded into a whirlwind of...
