The World Data Center system works to guarantee access to solar, geophysical, and related environmental data. It serves the whole scientific community by assembling, scrutinizing, organizing, and disseminating data and information.” WorldWorld DataData CenterCenter forfor RemotelyRemotely SensedSensed LandLand DataData In the U.S., the World Data Center Coordination Office is managed by the U.S. National Academy of Sciences through its Committee on Geophysical and Environmental Data. In 1992, the USGS EROS Data Center was designated as a World Data Center for Remotely Sensed Land Data.

LandsatLandsat ProgramProgram The longest-running enterprise for acquisition of moderate resolution imagery of the Earth from space. Landsat 1 was launched in 1972. The most recent, Landsat 7, was launched in 1999. Instruments on the Landsat satellites have acquired millions of images. These images form a unique resource for applications in agriculture, geology, forestry, regional planning, education, mapping, and global change research.

LandsatLandsat ProgramProgram The objective of the Landsat Program is to ensure a collection of consistently calibrated Earth imagery. Landsat’s global survey mission is to establish and execute a data acquisition strategy that ensures repetitive acquisition of observations over the Earth’s land mass, coastal boundaries, and coral reefs; and to ensure the data acquired are of maximum utility in supporting the scientific objectives of monitoring changes in the Earth’s land surface and associated environment.
