German radar satellites “TerraSAR-X” and “TanDEM-X” are providing 308 terabytes of data to the German National Aeronautics and Space Research Center (DLR) for their project “Global Urban Footprints”. The results are maps in black and white. While this dichotomy is usually not recommendable in human geography and urban studies, it very much helps to reveal the true extent of spatial urbanization in the world (see picture gallery on Spiegel Online). If everything works as planned, the DLR will make this data available to the research community at the end of this year (2014) – without any doubt, it would be a big treasure and source to scientists and researchers from a variety of fields.
