Mission: Objectives: TanDEM-X Mission: TanDEM... DEM of somewhere in Bolivia Mission: Objectives: provision of X-band SAR-data for scientific research and applications establishment of a commercial Earth Observation (EO) market and to develop a sustainable EO-service business, based on TerraSAR-X derived information products http://www.terrasar.de/image-gallery http://ilrs.gsfc.nasa.gov/satellite_missions/list_of_satellites/tsar_general.html TerraSAR & TanDEM TanDEM-X Mission: Launched summer 2010 Goal: Create global DEM in 3 years 12 m. resolution, <2 m. vertical accuracy 1.5 petabytes expected 1,000,000,000,000,000 B (at 8bits/B) http://www.dlr.de/en/desktopdefault.aspx/tabid-1/86_read-4553/

Some of the many areas of use for TerraSAR data: security and defence  topographic and thematic mapping agriculture: crop mapping etc. see below!  forestry applications urban and regional planning  coastal management and vessel monitoring  geology hazard & disaster management Snow & Glaciers Below: Colour Composite of 3 TerraSAR StripMap (HH polarized) Images from different dates http://www.terrasar.de/
