The Gestalt Photo Mapping System is made up of the GPM II and GPM Plotting System. The GPM II is a computer-controlled, auto-correlating, analytical photomapper. It is composed of two scanners, an automatic image correlator, a control computer, an operator's console, and one or two printers. A typical stereomodel is completed automatically in less than an hour and a half after a 10 minute operator-assisted analytical orientation. Principal topographic output consists of a 700,000-point digital terrain model (DTM) on magnetic tape: Planimetric output consists of an orthophoto on 20 X 25 cm stable-base film. The GPM Plotting System is an off-line automatic DTM processing system. It consists of a disk-based minicomputer and plotter. Smoothed contours and slope maps may be plotted at map scale with annotation in less than an hour and a half. A GPM III orthophoto and GPM Plotting System contours may be combined without editing by using conventional photographic techniques to produce a reproduction-quality contoured orthophot map in less than a day. /Author/
