Digital geomedia empower students not only to describe features of their environment but also to help change it. Geoscience education may therefore help students claim their rights as citizens for a more sustainable future. This paper shows results from a European project financed through the Erasmus+ funding scheme. It is not designed to contribute to the scientific development within spatial education. Rather, it is meant to serve as a best practice example for teachers in Europe for how to connect different school subject areas within one project, in order to describe, analyse and help promote spatial citizenship, largely through the use of geomedia.

Several school projects have already proven the value of working with a GIS in the classroom. As a consequence, curricula in several European countries have included GI in education. But few groups/classes so far have used a professional GIS when creating maps. This project describes the results of a workshop that has been running for one-and-a-half years at an upper secondary school ("Gymnasium") in Munich, Germany. Neither the three teachers leading the workshop nor the students attending the workshop had any active knowledge about GIS when starting the project. At the end of the workshop period the group had devised a complete digital plan for urban development (calculated for ten thousand inhabitants) in an undeveloped area in the north of Munich, using ArcGIS.
