SRTM
The goal of the Shuttle Radar Topography Mission (SRTM), a joint project of NASA, NIMA, and the German and Italian space agencies, is to map the world in three dimensions. In its 11-day mission on STS-99 in February 2000, SRTM collected an unprecedented 8.6 Terabytes of interferometric C-band Synthetic Aperture Radar (SAR) data (equivalent to about 14,317 CDs). This data will be processed to produce a rectified terrain-corrected mosaic of approximately 80% of the Earth's land surface topography (between 60 degrees North and 56 degrees South latitude) at 30-meter resolution. Aviation safety, coastal zone management, disaster management, homeland security, smart growth for infrastructure.
