Abstract :
Interferometric DEMs in steep mountains are a challenge even for high coherent single pass sensors like SRTM. This work compares shadow and lay-over problems for SRTM and ERS and shows how multiple interferometric observations could be used to compute a consistent DEM of an alpine region
