Satellite remote sensing has experienced tremendous development in recent years. Possibilities in earth observation have rapidly improved in terms of spatial and temporal data acquisition. A spatial resolution in the sub-meter area and daily situation updates from numerous sensors offer new possibilities for disaster management. Particularly in case of a large scale flood event, satellite rapid mapping has repeatedly proven its effectiveness. The last application in Switzerland dates back to the flood event of 2005. Furthermore, a lack of end-user studies on the cantonal level was asserted. An assessment of the current potential of satellite rapid mapping was therefore demanded.
