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.
Gift of Amrom H. Katz
Base board and transparent sector overlays used to present a graphic and dynamic analysis of the oblique photograph; also determines coverage, nadir point distances and effective altitudes.
