- Topography | NASA Earthdata
NASA's topography data offer essential measurements that help inform human planning, protect ecosystems, and explain Earth's land processes
- Digital Elevation Terrain Model (DEM) | NASA Earthdata
Digital Elevation Models, or DEMs, are three-dimensional models of the “bare earth” surface, showing elevation and topography without trees, buildings, or other objects DEMs are important in many different applications, including predicting wildfire behavior, planning for ecological conservation, and creating realistic models of water flow and flood risk
- 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
- Shuttle Radar Topography Mission Version 3. 0 (SRTM Plus) Product . . .
NASA's LP DAAC released the NASA Shuttle Radar Topography Mission Version 3 0 (SRTM Plus) collection
- Sea Surface Topography - NASA Earthdata
Ocean surface topography is the height of the ocean surface from the geoid, or surface on which the Earth’s gravity field is uniform While the ocean looks perfectly flat to us from the shore, waves, tides, currents, and variations in atmospheric pressure cause variations in sea surface height across the globe Tracking these variations helps us better understand the way ocean circulation
- NASA Shuttle Radar Topography Mission Global 1 arc second V003
The Land Processes Distributed Active Archive Center (LP DAAC) is responsible for the archive and distribution of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) version SRTM, which includes the global 1 arc second (~30 meter) product NASA Shuttle Radar Topography Mission (SRTM) datasets result from a collaborative effort by the National Aeronautics and
- Surface Water and Ocean Topography - NASA Earthdata
NASA's Surface Water and Ocean Topography (SWOT) platform monitors Earth’s surface water, collecting data to contribute to the first global survey of the Earth's surface water
- NASA Shuttle Radar Topography Mission Global 3 arc second V003
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) SRTM, which includes the global 3 arc second (~90 meter) product The 3 arc second data was derived from the 1 arc second using averaging methods (See Figure 3 in the User Guide) The NASA SRTM data
