U.S. Geological Survey 19650927 Remote-Sensing Image U.S. Geological Survey Sioux Falls, South Dakota, USA https://doi.org/10.5066/F78P5XZM On February 24, 1995, President Clinton signed an Executive Order, directing the declassification of intelligence imagery acquired by the first generation of United States photo-reconnaissance satellites, including the systems code-named CORONA, ARGON, and LANYARD. More than 860,000 images of Earth's surface, collected between 1960 and 1972, were declassified with the issuance of this Executive Order. The National Archives and Records Administration (NARA) was given the responsibility for the original film and provide access to a duplicate copy for public viewing of the film. The USGS was also provided a dupe copy to support science products. Both NARA and the USGS provide access and product support for Declass-1 collection. Online requests for these data can be placed via the EarthExplorer interactive query system. EarthExplorer contains metadata and online samples of Earth science data. With EarthExplorer, you may review metadata, determine product availability, and place online requests for products. More than 40 percent of the imagery contains significant cloud cover. The use of browse imagery gives the user the opportunity to review a reduced spatial resolution image to determine whether or not the area of interest is covered and is or is not obscured by clouds. The Declassified Image collection was driven, in part, by the need to confirm purported developments in then-Soviet strategic missile capabilities. The images also were used to produce maps and charts for the Department of Defense and for other Federal Government mapping programs. The CORONA system provided a cost effective method to map the earth from space with stereo-optical images. CORONA demonstrated that the ability to adapt rapidly to a changing world is critical to the success of U.S. intelligence. This need to adapt grows even more acute as the pace of technological advancement increases. Data provided by CORONA offers beneficial information for environmentalists, scientists, scholars, and historians. Corner coordinate data is a critical component of the index information. Accuracy in locating corner coordinates varies according to how coordinates were derived and according to the accuracy of information used for the derivation. As a general rule, metadata corner points have errors less than 10 miles from their actual ground positions for the CORONA and LANYARD systems, and less than 50 miles for the ARGON system. After a search of the metadata, the user should inspect the browse image and its immediate neighbors in the image series for the point of interest before placing an order. For example, each CORONA image is about 10 miles wide and looking at three consecutive images in a series will compensate for 10 mile errors in corner point locations. Also, the use of browse imagery allows the user to review a reduced resolution image to determine whether or not a specific site is contained in the selected frame.

This is called the spectral signature. Other signatures such as tone (lightness or darkness), texture (surface roughness or smoothness), pattern, shadow, shape, and size are as important. Cloud cover has not been individually assessed for these images, however, it has been determined that over 40 percent of the data is obscured by clouds. We highly recommend that the user review the browse imagery before placing an order. These images were retrieved under rigid quality control and product specifications. custserv@usgs.gov U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center Customer Service Representative Mailing and Physical Address
