Paper Abstract

ASTER is an advanced multispectral imager with high spatial, spectral, and radiometric performances for an EOS-AM1 polar orbiting platform which will be launched with four other instruments in June 1998 and covers a wide spectral region from visible to thermal infrared by 14 spectral bands. To meet a wide spectral coverage, optical sensing units of ASTER are separated into three subsystems, that is, visible and near infrared subsystem, a short wave infrared subsystem, and a thermal infrared subsystem, depending on the spectral region from a technical point of view. This ASTER instrument configuration with multi-telescopes leads to necessity of the ground processing on the generation of level-1 data products which are radiometrically calibrated and geometrically registered. The concept of level-1 processing algorithm on the ASTER Ground Data System is described.
