The region around Cologne and Bonn

The region around Cologne and Bonn
Rectangular structures on Earth reflect the radar signals from the satellites TerraSAR-X and TanDEM-X well. Scientists from the German Aerospace Center (DLR) used the satellite data to examine the urban structures. Although the images show that the largest settlements along the river Rhine have grown in the region between Cologne (on the left in the image) and Bonn, numerous smaller villages are also dotted across the surrounding rural regions.
