Mapping the earth in 3D
The satellites pair TanDEM-X and TerraSAR-X will start soon to compile a map of the earth with never reached accuracy. Following the succesfull launch of Tamdem-X, the second satellite of the pair, the work will start soon. In 2013, the 15 terabytes database will be complete.
Germany's second Earth observation satellite, TanDEM-X, was launched successfully on 21 June 2010 from the Baikonur Cosmodrome. Astrium in Friedrichshafen, Germany built the satellite and is sharing the costs (165 million Euros) for its development and operation. Together with its twin TerraSAR-X, in space since 2007, TanDEM-X will survey the entire surface area of the Earth - 150 million square kilometres - several times over from an altitude of 514 kilometres within three years.
