Abstract
Abstract A system for correlating electronic distance measurement and aerial photography where an airborne electronic location station is photographed as it passes over an area to be surveyed. The position of the airborne station is precisely measured as it moves and this information is included in the final image processing.

A system for correlating electronic distance measurement and aerial photography for the extension of geodetic control comprising; a plurality of electronic distance measuring stations positioned at precisely located points around an area of unknown geodetic control; a plurality of signal beacons located within area of unknown geodetic control; an airborne electronic location station having means for transmitting and receiving signals to and from said stations and said beacons; means carried by said airborne station for calculating distance, from said stations and beacons; and means for photographing the airborne electronic location station as it calculates its distance to stations and beacons, whereby said correlated precision measurement information and photographic data are suitable for photogrammetric analysis.
