Unseen Extremes - Mapping the World's Greatest Mountains by Stefan Dech and Reinhold Messner

Unseen Extremes marks a new milestone in Earth observation and Alpine exploration, presenting thirteen of the worlds great mountains in a manner never seen before. The German Centre for Aviation and Space Travel created very precise digital pictures of the mountains with the aid of satellite photographs taken from a height of several hundred kilometres. Scientists used these to produce models of the terrain, which were finally turned into photorealistic, virtual views from perspectives and heights that had been hitherto impossible.
