Topography | NASA Earthdata NASA's topography data offer essential measurements that help inform human planning, protect ecosystems, and explain Earth's land processes
Shuttle Radar Topography Mission (SRTM) | NASA Earthdata The Shuttle Radar Topography Mission (SRTM) payload flew aboard the Space Shuttle Endeavour during the STS-99 mission SRTM collected topographic data over nearly 80% of Earth's land surfaces, creating the first-ever near-global dataset of land elevations
NASA Shuttle Radar Topography Mission (SRTM) Version 3. 0 . . . - Earthdata The Land Processes Distributed Active Archive Center (LP DAAC) recently released additional tiles in NASA's Shuttle Radar Topography Mission (SRTM) Version 3 0 Global 1 arc second dataset (SRTMGL1), to include coverage over Asia and Australia This coincides with the newly processed areas released by the United States Geological Survey (USGS) on January 2, 2015
NASA Shuttle Radar Topography Mission Global 1 arc second V003 NASA Shuttle Radar Topography Mission (SRTM) datasets result from a collaborative effort by the National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA - previously known as the National Imagery and Mapping Agency, or NIMA), as well as the participation of the German and Italian space agencies
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
NASA Shuttle Radar Topography Mission Global 1 arc second number V003 Description The Land Processes Distributed Active Archive Center (LP DAAC) is responsible for the archive and distribution of NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Shuttle Radar Topography Mission (SRTM), which includes the global 1 arc second (~30 meter) number product
SWOT Data Products Fully Validated - NASA Earthdata After years of pre-launch preparation and 18 months of post-launch effort, all science data products from the Surface Water and Ocean Topography (SWOT) mission are fully validated
SWOT Swath Visualizer | NASA Earthdata The NASA's Surface Water and Ocean Topography (SWOT) Swath Visualizer allows users to investigate the coverage of Earth's surface by two SWOT instruments—the KaRIn Interferometer and altimeter—by interacting with the tool The map shows 21 days of tracks, after which the satellite will repeat its pattern of data acquisition Users can search for places of interest to obtain swath information
