Aster Dem Download ((hot)) May 2026

The ASTER Global Digital Elevation Model (GDEM) is a high-resolution topographic dataset providing nearly global coverage of Earth's land surface. Developed through a collaboration between NASA and Japan’s Ministry of Economy, Trade, and Industry (METI), this data is a cornerstone for researchers in geology, hydrology, and urban planning. What is ASTER DEM?

The ASTER GDEM is generated from data captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), an instrument aboard NASA's Terra satellite. It utilizes along-track stereoscopic imaging to create a 3D representation of the terrain. The ASTER Global Digital Elevation Model (GDEM) is

Version 3 (GDEM V3), released in 2019, features improved spatial resolution, higher accuracy, and fewer artifacts compared to previous versions. How to Download ASTER DEM Data ASTER Global Digital Elevation Map 83° North to 83° South latitude (99% of Earth's landmass)
