Calculator, Graphic, Oblique, Aerial Type A-1, Prototype, with 18 Transectors

Calculator, Graphic, Oblique, Aerial Type A-1, Prototype, with 18 Transectors

     

At Wright Field, Ohio, Amron Katz developed the aerial photographic computer to solve mathematical problems in aerial photography. It consists of a base board computer, on which are drawn the coordinate axes (altitude and ground distance), and 18 mylar overlays, one for each type of camera used. The computer can calculate photographic coverage, nadir point distances, and effective altitudes.
