The Skylab Earth Resources Experiment Package used two photographic remote sensing systems and was designed to be used by the scientific community. Each camera used 70 mm film and a six-inch focal length lens. It utilized five-inch film and a 18inch focal length lens. The images covered a number of NASA pre-selected test sites. Extent of Coverage Vertical Gemini coverage is generally worldwide between 33 degrees North and 33 degrees South latitude.
Oblique imagery includes areas beyond the vertical coverage range.
Apollo coverage is global including oblique imagery with most of the vertical photography existing between 33 degrees North and 33 degrees South latitude. Acquisition Combined, the Gemini, Apollo, and Skylab missions contain 63,217 frames of imagery. The imagery were obtained from either astronaut hand-held or spacecraft attached film camera systems.
