Open Source GIS Consultancy, Training & Coaching

Do you need help with
Open Source GIS?

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 60k 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.
