I'm Hans van der Kwast. With more than 20 years of experience with GIS and Remote Sensing in education and projects, I'm now offering consultancy, training and coaching in open source GIS. I'm an active member in the QGIS community, a QGIS certified trainer, and board member of the Dutch QGIS User Group. I've established the GIS OpenCourseWare platform for sharing free course materials on QGIS, Python, Mergin Maps, Google Earth Engine and much more. The PCRaster Tools plugin for QGIS that I've developed has been downloaded more than 90k times. Furthermore, I'm co-author of the book QGIS for Hydrological Applications and I have a YouTube Channel with more than 30k subscribers. As a member of QCooperative, I'm well connected with the best open source GIS developers.
I offer online consultancy on GIS work flows with QGIS, Mergin Maps, Python, PCRaster, WebODM, GDAL and other open source software.
I create online tailor-made training on open source GIS software and Python. For QGIS I provide the official QGIS certificate.
I provide online coaching sessions to beginning and more advanced GIS professionals. Topics for coaching could be on open source business model development, marketing or GIS career development.
Check my YouTube Channel, QwastTube and the GIS OpenCourseWare platform for free videos and step-by-step tutorials. These come without support and without certificates.
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.
