An overview of the Landsat Data Continuity Mission

摘要

The Landsat Data Continuity Mission (LDCM) is the follow-on mission to Landsat 7 and will be the eighth mission inthe Landsat series. The mission is in development via an interagency partnership between the National Aeronautics andSpace Administration (NASA) and the Department of Interior (DOI) / United States Geological Survey (USGS). TheLDCM satellite will carry two earth-observing sensors, the Operational Land Imager (OLI) to collect image data for ninespectral bands in the reflective portion of the spectrum and the Thermal Infrared Sensor (TIRS) to collect coincidentimage data for two thermal spectral bands. The LDCM ground segment will control the satellite and will receive,process, archive, and distribute the science data collected by the OLI and ТIRS instruments. The USGS Earth ResourcesObservation & Science Center (EROS) will distribute LDCM data products at no cost to requestors. The missionobjective is to continues the Landsat program's collection, archive, and distribution of multispectral imagery affordingglobal, synoptic, and repetitive coverage of the Earth's land surfaces at a scale where natural and human-induced changescan be detected, differentiated, characterized, and monitored over time. The LDCM launch readiness date is currentlyDecember, 2012.
