On March 5, 2007, NASA's Land Processes Distributed Active Archive Center (LP DAAC) started offering a new suite of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Level-3 on-demand orthorectified Image products. An orthorectified image is similar to a map with near-vertical views for every location. These products are generated using ASTER Level-1A data and a DEM derived from the same data.
Two product suites are offered:
- AST14OTH is the short name of the ASTER on-demand Level-3 Orthorectified Image product, which includes fifteen orthorectified ASTER Level-1B calibrated radiance images, one per each band, including Band 3B.
- AST14DMO is the short name of the ASTER on-demand product comprised of both the Level-3 DEM and Orthorectified Image product. The distributed product is a multi-file containing both a DEM, and fifteen orthorectified L1B calibrated radiance images, one per each band.
