NASADEM Merged DEM Global 1 arc second V001 - Earthdata Description 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) Digital Elevation Model (DEM) version 1 (NASADEM_HGT) dataset, which provides global elevation data at 1 arc second spacing
ASTER Global Digital Elevation Model V003 | NASA Earthdata Description The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator)
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
