The German satellite
TanDEM-X was launch into orbit on a mission to map more accurate to be made
available to the surface of the Earth. The satellite will fly radar technology
with identical platform called TerraSAR-X launched in 2007. Both measured
variations in the height of the globe with an accuracy of better than two
meters.
Its digital elevation
model will have many uses, from helping military jets fly ultra low height to
show where rescue workers was worse the damage caused by an earthquake.
