LP DAAC Announces New ASTER Level-3 Orthorectified Image Products

On March 5, 2007, the LP DAAC started offering a new suite of 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:

1. 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.


2. 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.
