4 days ago · NASA's data for digital elevation models (DEM) comes from airborne and space-based sources and are useful for analyzing a majority of Earth's terrain.
We propose a significant modernization of the publicly- and freely-available DEM data. Accurate surface elevation information is a critical component in scientific research and commercial and military.
Description The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation.
Dec 7, 2021 · 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.
Dec 29, 2025 · This recipe from NASA's Alaska Satellite Facility guides you through creating a Digital Elevation Model (DEM) from two Sentinel-1 SLC scenes. Follow the steps: create an interferogram,.
