DThe sub-project Earth Observation investigates the ground displacements in Thuringian Basin for the purpose of retrieving general information on surface dynamics, i.e. gaining knowledge on the active processes taking place in the basin. In order to derive the spatio-temporal evolution of the surface dynamics, differential interferometric synthetic aperture radar (dInSAR) is utilized which allows the detection of displacements rates in the mm per year range. Special emphasis is put on surface movements created by ground water level changes as well as subrosion or mining-induced subsidence. For this purpose, multi-sensor radar data covering different seasons, weather conditions and ground water levels are interferometrically analyzed.
