RESEARCH IN ANALYTICAL PHOTOGRAMMETRY IN APPLICATION TO TRANSPORTATION SURVEYS. FINAL REPORT

Research was conducted on applications of analytical photogrammetry to selected measurement tasks typical of surveying requiremetns of departments of transportation. A system calibration procedure was established for analytical photogrammetric applications using aerial photography at scales of approximately 1 to 5000. For this purpose, an accurate test range was established at the Transportation Research Center of Ohio where the average standard eror of an adjusted line length was 0.010 feet. A method of photolog image measurement using an IMB-PC programmed in MBASIC and a special P-CAT type comparator was developed. The accuracies in elevation produced by post block aerial surveying procedures applied to photography from the National High-Altitude Photography (NHAP) were assessed. When compared to withheld check points, the RMS error in elevation was about 3.5 feet for photography at 1:80,000 scale (altitude of 40,000 feet). A computer program titled BY4 was prepared in FORTRAN IV to adjust observations of photcoordinates, exterior orientation, survey coordinates and interior orientation in a simultaneous adjustment. Special attention was given to the exploitation of sparsity patterns that were characteristic of the photogrammetric procedure. Recommendations for refinements in the procedures and hardware for the measurement tasks were made.
