Scientists from NASA’s JPL announced the release of high-resolution topographic data of the continental United States acquired during the Shuttle Radar Topography Mission (SRTM) on Space Shuttle Endeavour in February 2000. Project scientists planned to process the digital- elevation-model (DEM) data, sampled at an interval of one measurement every 30 meters (98 feet), into the most detailed three-dimensional topographic maps ever made of Earth. The SRTM data would eventually include 1 trillion measurements, representing nearly 80 percent of Earth’s landmass between 60° north and 56° south of the equator, a mapped area in which nearly 95 percent of the world’s population resides. SRTM project scientists anticipated that the maps produced from the mission would provide the most valuable and universally beneficial data produced by any scientific mission. Scientists would be able to use the data in applications ranging from flood control to transportation and urban planning.
