At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.

Teachers and parents can always find something to intrigue their students in the EROS library of educational resources!

The U.S. Geological Survey (USGS) EROS Center is government-owned/directed and contractor-operated. The work of EROS is carried out through a number of mission-support contracts with industry. The largest contract, the Technical Support Services Contract, is held by KBR. Its purpose is to provide the USGS with support in the areas of science, engineering, and technical operations. Other USGS contracts provide support in the areas of satellite mission operations, facility operations and maintenance, custodial services, and physical security.

EROS also partners with educational institutions by offering internships and research opportunities, and by supporting the U.S. Geological Survey's student jobs program and the Mendenhall Research Fellowship Program for post-graduate students.
