Varied elevations of Bachu in western China in an image developed using data from the two ERS satellites. The ERS missions pioneered the technique of processing satellite radar data into digital elevation models, as shown here of Bachu and the nearby Tian Shan mountains. A digital elevation model is a 3D relief map to study changes in the terrain.
