IV. Conclusion With the advent of economically feasible analytical stereoplotters, such as the AUTOPLOT from Systemhouse, the rigorous process of controlling, acquiring and setting-up that is now associated with terrestrial photogrammetry, can be relaxed. This relaxation should not be considered sloppiness. It should, however, be viewed as an opportunity to redirect the photogrammetric community's efforts away from exotic camera and operator procedures and towards expanding the everyday applications of photogrammetry as a profitable endeavor. 34
1. Introduction PRACTICAL EXPERIENCE IN INTEGRATING CONVENTIONAL PHOTOGRAMMETRIC COMPILATION AND DIGITAL MAPPING TECHNIQUES John K. Powell Glenn L. Osick Thomas C. Miller U.S. Geological Survey 1400 Independence Road Rolla, Missouri 65401 V Since the mid-1970's, USGS has purchased, developed, or modified various photogrammetric instruments to collect standard map data in digital form. This instrumentation includes automatic image correlation instruments such as the Gestalt Photo Mapper II (GPM-2), as well as analyti cal stereoplotters and conventional stereoplotters retro fitted with three-axis digitizers. Two of the latest USGS digital mapping support systems are a stereoplotter interfaced with an M&S interactive editing system and the recently acquired Sci-Tex scanning and editing sys tem.
