Supercomputers will start building a 3D map of the world

The National Geospatial-Intelligence Agency is teaming up with the University of Illinois, the University of Minnesota and The Ohio State University to produce digital elevation models of the world through a project called EarthDEM. By feeding satellite images of an area from different angles into the Blue Waters supercomputer, the team will be able to create 3D models of the terrain. Blue Waters is one of the most powerful and fastest supercomputers in the world, capable of performing more than 13 quadrillion calculations per second.
