EORC PI Florian Betz was invited by the group of Remote Sensing of Environmental Changes at the University of Zurich to talk about his research on satellite time series based analysis of river systems. The visit was a great opportunity to exchange ideas and elaborate potentials for collaboration. There are great potentials for collaborating for instance in the analysis of historical satellite images or the extraction of 3D Information from imagery using photogrammetry. Potentially, there will also be opportunities for students to join the Remote Sensing of Environmental Changes group at UZH for internships.
