- Abstract
The U.S. Geological Survey’s Center for Earth Resources Observation and Science (EROS) hosts NASA’s Land Processes Distributed Active Archive Center (LP DAAC). The LP DAAC manages land data collected by NASA’s Earth Observing System (EOS), a series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. The LP DAAC is the only facility in the United States that archives, processes, and distributes Advanced Spaceborne Thermal Emission/Reflection Radiometer (ASTER) data from NASA’s Terra spacecraft. The LP DAAC also is responsible for the archive and distribution of “land products” generated from data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. ASTER and MODIS datasets are ingested by the LP DAAC electronically, at a rate of approximately 2 terabytes per day. These data are made available and distributed to the broadest possible user community through various capabilities, at a capacity of approximately 1 terabyte per day. Nearly 1.5 petabytes of remotely sensed land data are currently stored in the LP DAAC systems. In addition to ingest, archive, and distribution capabilities, the LP DAAC also processes ASTER data to generate higher level products. An on-demand processing system was implemented at the LP DAAC allowing the generation and distribution of ASTER Level-1B, Level-2, and digital elevation model products from any ASTER Level-1A data in the archived.
