Abstract : The primary purpose of the project is to optimize system hardware and computer programs and to develop and evaluate alternate correlation techniques. The objective is to prove conclusively the concept of digital map compilation. The system consists of a photodigitizer unit for scanning and digitizing a pair of stereo aerial diapositives, specially written computer programs for use on an IBM 7090 Computer to perform rectification, correlation, and ortho-correction on the digital photo data, and a photomap printer unit for printing the rectified photo or orthophotomap with or without contour and grid tic information.
