Do you need help with
Open Source GIS?

I'm Hans van der Kwast. With almost 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 20k times. Furthermore, I'm co-author of the book QGIS for Hydrological Applications and I have a YouTube Channel with more than 20k subscribers. As a member of QCooperative, I'm well connected with the best open source GIS developers.


Are you struggling with your GIS work flows?

I offer online consultancy on  GIS work flows with QGIS, Mergin Maps, Python, PCRaster, WebODM, GDAL and other open source software.

Do you need a GIS training?

I create online tailor-made trainings on open source GIS software and Python. For QGIS I provide the official QGIS certificate.

From 22 May to 2 June 2023 I'm giving a QGIS Introduction Training to Kadaster in Curaçao. It's fantastic that they're using QGIS and that they've invited me to give a training. This is the first in-person training abroad for QWAST-GIS.

I'm thrilled to share that I've received an award from TAG NG at IHE Delft Institute for Water Education for my contributions to Open Education in the Global South. This award recognises my efforts to create and disseminate high-quality educational resources that are accessible and affordable for learners around the world.
