OPTIMIZED DIGITAL MAPPING SYSTEM.
Abstract
The primary purpose of the DAMC project is to optimize system hardware and computer programs developed and to develop and evaluate alternate correlation techniques. The objective is to con clusively prove the concept of digital map com pilation. The system consists of a photo digitizer unit for scanning and digitizing a pair of stereo aerial diapositives, specially written computer programs for use on a IBM 7090 Computer to perform a rectification, correlation, and ortho-correction on the digital photo data, and a photomap printer unit for printing the rec tified photo or orthophotomap with or without contour and grid tic information. The investi gation section presents a detailed theoretical analysis of major portions of the DAMC system with particular emphasis on the non linearities associated with the CRT and optical equipment.
