ASTER data products exploit multi-spectral, high-spatial resolution combinations of VNIR (Visible and Near Infrared), SWIR (Shortwave Infrared), and TIR (Thermal Infrared) for land surface classification and change detection, soil and geologic studies, volcano monitoring, surface energy balance, surface temperature, emissivity and reflectivity determination, and cloud studies.
VNIR and SWIR bands are used for investigation of land-use patterns and vegetation, VNIR and TIR combinations for the study of coral reefs and glaciers, and VNIR for digital elevation models (DEMs).TIR channels are used for study of evapotranspiration and land and ocean temperature. The stereoscopic capability yields local surface DEMs and allow observations of local topography, cloud structure, volcanic plumes, and glacial changes.
Below are the standard data products that are available for the ASTER instrument. Other special products are produced by ASTER Science Team members.
