Earth Resources Observation and Science (EROS) Center

The EROS Data Center outside of Sioux Falls, South Dakota, is a USGS facility dedicated to collection and analysis of satellite and aerial data. It was placed in the center of the continent as a satellite facility that could downlink satellite data from coast to coast of the United States. EROS is also one of the largest data repositories in the country, with disk, tape, and film archives dating to the earliest days of the space program.
