Earth Observation (Remote Sensing) research and teaching activities are a fundamental part of the Geomatics Group. Remote sensing activities are mainly focussed on urban areas to identify urban building structures, urban green and blue infrastructure and valuable economic targets etc. and their changes with time. Associated to that is an interest in environmental justice as well as an interest in combined analysis of socio-economic and image data. The Big Data sources of satellite images require methodological approaches with artificial intelligence technology.
