DEVELOPMENT OF PHOTOGRAMMETRIC METHODS IN RIGHT-OF-WAY OPERATIONS

A PROCEDURE HAS BEEN DEVELOPED FOR MAKING PROPERTY SURVEYS BY PHOTOGRAMMETRIC METHODS USING THE NISTRI ANALYTICAL PLOTTER (AP/C). AN ANALYSIS IS MADE OF THE PROBLEMS ENCOUNTERED WITH DEED DESCRIPTIONS IN THE PROJECT. AERIAL PHOTOGRAPHS SHOWING OWNERSHIP BOUNDATIES IN RURAL AREAS WERE OBTAINED FROM THE U.S. DEPARTMENT OF AGRICULTURE. THESE WERE FOUND USEFUL IN ESTABLISHING THE PRELIMINARY LOCATION OF PROPERTY LINES. A STATISTICAL ANALYSIS IS MADE OF THE ACCURACY OF MEASURING THE LOCATION OF PROPERTY CORNERS WITH THE AP/C. FOR 1:12000 SCALE PHOTOGRAPHS THE STANDARD DEVIATION OF THE ERRORS FOR 28 POINTS TESTED WAS 0.549 FOOT. IT IS BELIEVED THAT GREATER ACCURACY COULD BE ACHIEVED BY USING SPECIAL OPTICAL REFLECTIVE DEVICES TO PREMARK PROPERTY CORNERS AND OTHER CRITICAL POINTS ON THE GROUND BEOFRE THE PHOTOGRAPHIC FLIGHT. INADEQUACIES IN OLD PROPERTY SURVEYS, RESTRICTED USE OF THE STATE PLANE COORDINATE SYSTEM, LACK OF TRAINED PERSONNEL, AND LACK OF RECOGNITION OF PHOTOGRAMMETRY FOR LAND SURVEYING BY THE COURTS, HAS BEEN SUGGESTED AS THE REASONS FOR THE SLOW PROGRESS IN ADOPTING PHOTOGRAMMETRIC METHODS FOR RIGHT-OF-WAY OPERATIONS. THE RECOMMENDATION IS MADE TO MODIFY BY LEGISLATION OHIO'S STATUTORY DEFINITION OF LAND SURVEYING TO INCLUDE PHOTOGRAMMETRY. A TENTATIVE PROCEDURE FOR RIGHT-OF-WAY PLAN PREPARATION BY PHOTOGRAMMETRY IS DESCRIBED. /BPR/
