Reprinted from PHOTOGRAMMETRIC ENGINEERING April 1956 Hydrographic Application of Photogrammetry ın the United States Coast and Geodetic Survey” G. C. TEWINKEL, U. S. Coast and Geodetic Survey T publication of nautical charts of the coastline of the United States and its territories is one of the principal functions of the Coast and Geodetic Survey. The term “publication” here implies not only printing the charts, but also their construction and maintenance from the establishment of basic control surveys to the application of most recent changes. The problems encountered in providing this service differ somewhat from those of general topographic map- ping inasmuch as (1) the area is usually confined to a narrow, irregular strip along the coast, (2) the scale is relatively large, and (3) intensive detail is re- quired to serve an accurate and complete guide to the mariner. The advantages offered by photogrammetry are used to obtain basic topographic information and to aid the hydrographer. The Photogrammetry Division is one of the six operating divisions of the Coast and Geodetic Survey, the others being Coastal Surveys, Geodesy, Geo- physics, Tides and Currents, and Charts. Although the functions of the various divisions are fairly well denoted by their titles, it may be added that the Coastal Surveys Division operates the hydrographic vessels and performs the hydrographic surveys; the Photogrammetry Division provides, through the use of aerial photography, the topographic and control information required to locate inshore hydrography and to compile and maintain the nautical charts; and the Charts Division compiles, engraves, prints, and distributes the charts. The Photogrammetry Division, in turn, utilizes data provided by the Geodesy Division and the Tides and Currents Division, and supplements such data with observations of its own whenever it is advantageous. The Photogrammetry Division comprises an unusually complete organiza- tional unit. It owns its aerial cameras and the navigator and photographer are members of the Division. It processes its own film and reproduces its prints, enlargements and diapositives. The Division operates its own mobile field parties and compilation offices. It has a series of stereoscopic plotting instru- ments for nearly every appropriate application. A drafting unit is included for finishing and scribing the completed manuscripts. A small research group stud- ies new techniques and strives to improve the old ones. The different phases of the work are united through an Operations Branch. By this complete organi- zation, the Division is able to control and coordinate its activities including flicht planning, aerial photography, control surveys, compilation, drafting, etc. The photographic airplane is provided by another bureau, the U. S. Coast Guard, which cooperates completely in supplying the service when and where it is required. Additional airplane service is obtained through private firms by a contract arrangement whereby the Division's navigator-pilot and photog- rapher operate the equipment. * This paper is a contribution to Commission IV of the International Society of Photogram- metry.
