Paper Abstract

In addition to acquiring multispectral data, the advanced spaceborne thermal emission and reflectance radiometer (ASTER) will also acquire along-track stereo data. ASTER is capable of acquiring 771 digital stereo pairs per day, each covering 60 by 60 km on the ground, at 15 m resolution with a base/height ratio of 0.6. According to present plans, approximately 30 digital elevation models (DEMs), with 7 - 50 m accuracy (RMSExyz) will be produced daily. During the 5 year mission on the EOS AM1 platform, ASTER has the potential to provide a coherent digital stereo dataset covering the Earth's land surface. At minimum, DEMs derived from these data will augment topographic data from other sources. These fundamental geophysical measurements will be a major contribution to interdisciplinary studies of the Earth as a planet.
