Comparison of Landsat-7 Enhanced Thematic Mapper Plus (ETMplus) and Earth Observing One (EO-1) Advanced Land Imager

摘要

The Earth Observing One (EO-1) satellite was launched from Vandenberg Air Force Base on 21 November 2000 as the first Earth observing platform of NASA's New Millennium Program. As part of this effort, NASA formed a Science Validation Team (NRA 99-OES-01, EO-I) to contrast and compare the new sensor technologies with proven sensors such as the Enhanced Thematic Mapper Plus (ETM+) on the Landsat-7 spacecraft. In this paper we present some of our comparisons of the Advanced Land Imager (ALI) and the ETM+ as part of this effort. Additionally, EO-1 camed Hyperion, an advanced hyperspectral sensor. We do not discuss this instrument in detail here, but do make use of its capability to extract reflectance spectra for comparisons with the ALI and ETM+.
