Digital Elevation/Terrain Model (DEM) Data Access and Tools
NASA's digital elevation model (DEM) data provides measurements across a majority of Earth's interior, shore, and coastal areas. Our datasets and tools help researchers translate these interconnected data points into actionable knowledge.
Featured Digital Elevation/Terrain Model Observation Method: ASTER
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a high spatial resolution instrument aboard the Terra satellite. ASTER provides a Global Digital Elevation Models (GDEM) of Earth's land surface at approximately 30-meter spatial resolution.
Version 3 of the ASTER Global Digital Elevation Model (GDEM) provides new features and sharper imagery.
These products are available globally at their full resolution of 30 meters per pixel.
Looking for synthetic aperture radar (SAR) data? Learn how to discover, access and manipulate SAR data with the newly revamped NASA ASF DAAC Vertex tool. We'll showcase common data access methods and some of the advanced features of this data discovery and data access tool.
NASA's Commercial Satellite Data Acquisition program enables this Satellite Needs Working Group solution by providing access to two 2.0 m Digital Elevation Model (DEM) products.
