COMMISSION IV WI | Aopendix to the INT, ARCHI | DTOGRAMMETRY, Vol. Xlk4, *^75 : Reprinted from PHOTOGRAMMETRIC ENGINEERING April 1956 Economic Factors in the Integrated Photogrammetric System of the U. S. Geological Survey*t GEORGE D. WHITMORE, U. S. Geological Survey "T United States Geological Survey is now in the process of affecting im- portant changes in its mapmaking procedures. These integrated changes affect all the major aspects of the topographic mapping operation: aerial photog- raphy, photogrammetric instruments, plotting techniques, field operations, cartographic finishing, and reproduction processes. It is the purpose of this paper to review the economic background of this transformation and to discuss, in simple terms, advantages of the new system from the economic point of view. To begin with, a brief outline of the principal changes in instrumentation needs to be stated, so that the transformation can be viewed in proper perspec- tive. Prior to instituting the new system, the Geological Survey operated some 350 Multiplex plotting units, utilizing some 800 Multiplex projectors, including those used in bridging. In addition, 69 Kelsh plotter units and 9 heavy plotter units were in operation. Under the new system, the Multiplex projectors are being replaced by ER-55 projectors, to be used principally with twin low- oblique photography. Also, Twinplex plotters are being installed for aerotri- angulation of twin low-oblique photography. Because of increased efficiency resulting from the new techniques and instrumentation, the planned replace- ment rate is 2 units of ER-55 equipment for 3 units of Multiplex equipment; * This paper is a contribution to Commission IV of the International Society of Photogram- metry. tPublication authorized by Director, U. S. Geological Survey. U.S.A.-1
