Topographic Map Of The World

Here are some samples of the most complete and detailed topographic map of the world, compiled from satellite data.

Created From 1.3 Million Stereo Pairs

The new global digital elevation model of Earth was created from nearly 1.3 million individual stereo-pair images collected by the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or Aster, instrument aboard Terra. NASA and Japan's Ministry of Economy, Trade and Industry, known as METI, developed the data set. It is available online to users everywhere at no cost. (source)
