The path to mapping the global urban footprint using TanDEM-X data
نویسندگان
چکیده
Global mapping of urban environments is a challenging task. Earth observation is probably the only source possibly providing a consistent and area-wide data set. With the German TanDEM-X mission two global coverages of high resolution radar data will be available for 2011 and 2012. While the main task of the mission is the derivation of a global digital elevation model, the collected data will additionally be used to classify urban areas. This paper gives an overview on the data sets, the method to derive urban footprints, the products and its accuracy.
