Forget Google Maps: NASA and Japan’s Ministry of Economy, Trade and Industry have released the most detailed three-dimensional map of Earth yet. It covers our planet between the 83 north and 83 south parallels thanks to 1.3 million stereo images.
The images were captured by ASTER, and then stitched together into a seamless map. ASTER—Advanced Spaceborne Thermal Emission and Reflection Radiometer—is the instrument taking maps of land surface temperature, reflectance and elevation flying onboard NASA’s Terra satellite. Once the Global Digital Elevation Model was complete, it was divided into 23,000 GeoTIFF file, each covering 1 x 1 degree of the globe. You can download the map here. [JPL]
