A group of 17 panoramic monochrome photographic prints of the Earth from an orbital satellite, various sizes, ranging in width from 9-1/2 to 12 inches, and in length from 36 inches to approximately 20 feet. Subjects are mostly cloud cover, but also some land masses, some marked, others identifiable from images. Locations identified include Florica and the Southeast U.S., the Great Lakes, Mexico, South America, Japan, Siberia. Some are dated, between 1975 and 1977. These photos appear to be from DMSP (Defense Meteorological Satellite Program) 5D1/F1 orbital satellite, operated by the U.S. Air Force, and declassified in March 1973. The images were created using an Operational Line Scan (OLS) system developed by Westinghouse, providing visual spectrum and infrared cloud cover data at a resolution of 1/3 nautical mile for major land masses, and 1-1/2 nautical miles for broader global scanning.
