Situated in the middle of the Swabian Jura, the Nördlinger Ries is a flat, almost circular structure measuring about 20 kilometres in diameter. Gradually filled in and flattened by erosion, the crater was caused by the impact of a meteorite about 15 million years ago. At its centre stands the town of Nördlingen, surrounded by fields which are cultivated, as documented by the structures that radiate away from the city.
In the centre of Nördlingen, the photograph shows the completely preserved ring wall that surrounds the old town.
The data furnished by TerraSAR-X permit studying microstructures in detail as well as analysing surface formations and land use. In this extensively cultivated region, which besides is of great geological interest, the radar data supplied by TerraSAR-X will be an important source of information for analysis as well as for improving agricultural utilisation.
