ANALYTIC AEROTRIANGULATION UTILIZING SKYLAB EARTH TERRAIN CAMERA (S-190B) PHOTOGRAPHY

The feasibility of utilizing Skylab spacercraft Earth Terrain Camera (S-190B) 1:946,000 scale photography in analytic aerotriangulation procedures to provide low-order, high-density control suitable for small-scale mapping operations was investigated. The long-range application is the employment of this technique for coastal zone mapping at medium and small scales, surveys in remote ares, forest and range management, various planning activities, and route location for highways, pipelines, transmission lines and canals. The National Oceanic and Atmospheric Administration, National Ocean Survey (NOAA/NOS), office- identified the locations of 29 photo control points of known position and elevation on a strip of 12 photographs ranging along a 350-mile track from Charlotte, North Carolina, to the Rappahannock River in Virginia. The coordinates of pertinent images on each photograph were observed on comparators operated by NOS, and the resulting data were then processed through an established analytic aerotriangulation system of computer programs. A block adjustment was performed holding to 14 of the office- identified photocontrol points. The accuracy of the solution was evaluated by comparing the analytically computed ground positions of the 15 withheld photo control points with their known ground positions. A horizontal position RMS error of 15 metres was attained. The maximum observed error in position at a control point was 25 metres.
