摘要：

The goal of the current Landsat mission is to acquire annual data sets of optical band digital imagery of the landmass of the Earth, Ground spatial resolutions for the panchromatic, reflective and emissive bands are 15, 30 and 60 meters, respectively. The design life for the Enhanced Thematic Mapper Plus (ETM+) imager on the Landsat-7 satellite is five years. The satellite was launched on April 15, 1999. The mission builds on the 27-year continuous archive of thematic images of the Earth from previous Landsat satellites. Early results from the ETM+ instrument, the spacecraft, and the ground processing indicate that the image quality is as good as expected and all systems are working. Partial Aperture Solar Calibrator (PASC) 100-day radiometric background stability is similar to +/-0.1 %. Full Aperture Solar Calibrator (FASC) 2-day stability is similar to +/-0.2 %. Mid-scale per pixel noise is similar to +/-1.0 %. Operational collection of Landsat's Long Term Acquisition Plan (LTAP) started June 29th. NASA Goddard Space Flight Center (GSFC) is responsible for the instrument, spacecraft, launch, flight operations and science team investigations. On October 1, 2000 USGS EROS Data Center (EDC) takes over flight operations while continuing archiving, monitoring quality, and distributing the imagery without restrictions on reprocessing and redistribution.
