Remote Sensing and GIS Studies of the Hegau Volcanic Area in SW Germany

GIS integrated geomorphologic and structural-geologic evaluations of satellite imageries and SRTM- and ASTER- DEM-data from the Hegau-area in SW-Germany provide information of the structural pattern of the sub-surface. The area is characterized by Tertiary volcanic domes, Tertiary molasse sediments forming ridges and scarps and flat to undulated, Quaternary glacial-related morphologic sequences. Traces of circular features can be identified on morphometric maps derived from DEM data and on LANDSAT- and satellite radar imageries providing information of the volcanic structures. Linear features visible on the different satellite imageries are mapped and correlated with known tectonic data. It becomes evident how far the landscape development of the Hegau-area has been influenced by sub-surface, magmatic structures.
