Photogrammetric Engineering and Reservoir Planning

Abstract

By using the precise measuring equipment available through and for Photogrammetric Engineering, a complete reservoir site study may be economically and comprehensively effected in a minimum time. The guidance of the professional in programmetry is essential from the first system design through final accomplishment. Equipment available and applicable are the fine aerial cameras, theodolites electronic distance measuring devices, coordinate measuring stereophotogrammetric equipment, data recording devices, electronic computers, processers, and plotters. Using these tools and the services of trained professionals and technicians in their respective phases of work aerial photographs through interpretation permit drainage area determination, soils typing, geologic land form determination, land use, cover dam site selection topographic mapping, property mapping and evaluation surveys, and subsequent systems design for service facility relocation, irrigation, power generation, flood control and real estate subdivision. The system described is based on property coordinated surveys with points paneled before photography and tied to the state standard system. Coordinates of objects in the photographs may be obtained photogrammetrically and processed with electronic computers. Properly preserved points and records may be readily retrieved for subsequent use.
