Declassified Satellite Imagery - 1 consists of approximately 880,000 photographic images that were taken between 1959 and 1972. These images were primarily collected by the CORONA satellite series, but the dataset also includes photos taken from the ARGON and LANYARD satellites. The images have multiple scales and the image quality can be variable. Cloud cover is common. The digital products are produced from a duplicate negative source. The original film and technical mission-related documents are maintained by the National Archives and Records Administration (NARA)

The above sizes may vary due to scanning more than just image data. With our policy to scan the surrounding metadata and the addition of the USGS logo the actual image size will generally be larger than the estimates above.
