Summary
Abstract: The ASTER Digital Elevation Model (DEM) is a product that is generated from a pair of ASTER Level-1A images. This Level-1A input includes bands-3N (nadir) and -3B (aft- viewing) from the Visible Near Infra-Red telescope's along- track stereo data that is acquired in the spectral range of 0.78 to 0.86 microns.

These relative DEMs can be used to derive absolute slope and slope aspect which is good up to 5 degrees over a horizontal distance of over 100 meters. ASTER DEMs are expected to meet map accuracy standards for scales from 1:50,000 to 1:250,000.

V002 data set release date: 2001-03-06
V003 data set release date: 2002-05-03
The key determinants between these versions are the use of a newer algorithm with an improved set of radiometric calibration and geometric correction coefficients databases in version 003.
