My activities at

As co-founder of mundialis, I see our company as a pioneer in the use and development of open source software for geographic information systems (GIS) and remote sensing. Inspired by the European Copernicus program, mundialis was founded in 2015 with the goal of making information from satellite data accessible. We use free geodata to create customized and future-proof map and data products and web services. Our expertise in open source development, combined with scientific know-how and agile project management, enables us to develop innovative methods using artificial intelligence and machine learning.

We believe in the quality and flexibility of open source solutions. Our work with GRASS GIS and the cloud-based geoprocessing platform actinia, which we continuously enhance and make available as free software, reflects this commitment. mundialis is not only a growing company with a dynamic team of experts, but also part of an active, collaborative community. We place great emphasis on environmental awareness and sustainability and strive to make a positive contribution to society and the environment through our work.
