Declassified Intelligence Satellite Photographs

Fact Sheet 090-96 (February 1998)


Recently declassified photographs from spy satellites are an important addition to the record of the Earth's land surface held by the U.S. Geological Survey (USGS).

More than 800,000 high-resolution photos taken between 1959 through 1972 were made available by Executive Order of the President. The collection is held at the USGS EROS Data Center, near Sioux Falls, S. Dak., and are offered for public sale. For some purposes in earth science studies, these photos extend the record of changes in the land surface another decade back in time from the advent of the Landsat earth-observing satellite program.

1992 Landsat Multi-spectral Scanner Image

In the Cape Canaveral, Florida, image pair (at right), the Landsat MSS image (acquired March 1992) shows how agricultural use of a marshy region near Cape Canaveral has expanded since the declassified image was acquired (Mission 9059A, October 30, 1963). In the declassified image, the region is dissected by ponds and small stream channels. In the Landsat image, acquired more than 28 years later, many of the small streams have been modified by dams and reservoirs, a network of roads has been constructed in the area, and agricultural development has increased.
