Digital Elevation Terrain Model (DEM) | NASA Earthdata A digital elevation model (DEM) is a three-dimensional graphic of the "bare earth" surface of land shown without trees, buildings or other objects DEMs can be created using traditional topographic maps, modern light detection and ranging (LIDAR) data and other sources gathered by airborne and space-based instruments NASA's DEM data, such as files collected by the Space Shuttle Radar
New in CSDA: High Resolution Digital Elevation Models High-resolution Digital Elevation Models (DEM) for non-polar regions at two-meter spatial resolution are now available through NASA’s Commercial SmallSat Data Acquisition (CSDA) program
New Version of the ASTER GDEM - NASA Earthdata The first ASTER GDEM was released in 2009, with Version 2 being released in 2011 The ASTER GDEM Version 3 maintains the GeoTIFF format and the same gridding and tile structure as in previous versions, with 30-meter spatial resolution and 1°x1° tiles Version 3 also features a new global product: the ASTER Water Body Dataset (ASTWBD
