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).

ASTER uses stereo imagery and photogrammetric techniques to extract DEM. This [4K Quality] video shows how to download and utilize Aster elevation data.
