ASTER is a satellite image that contains the Digital Elevation Model (DEM) information. ASTER stands for Advanced Spaceborne Thermal Emission and Reflection Radiometer. It has 15–90 square meters spatial resolution. ASTER has VNIR, SWIR and TIR data, but it is commonly renowned for its DEM, specifically the terrain height models (DTM).
