NUMERICAL METHODS FOR RADIAL TRIANGULATION

IN AN ATTEMPT TO REDUCE THE AMOUNT OF FIELD WORK NECESSARY IN PROVIDING CONTROL IN PREPARATION OF DETAILED TOPOGRAPHIC MAPS FROM AERIAL PHOTOS, THE POSSIBLE USES OF ESTABLISHING CONTROL BY MEANS OF RADIAL TRIANGULATION USING PHOTOGRAPHS WAS INVESTIGATED. EQUATIONS WERE DEVELOPED USING THE RESECTION AND INTERSECTION PRINCIPLES AND A DIGITAL COMPUTER PROGRAM WAS WORKED OUT FOR THEIR SOLUTION. THE EQUATIONS WERE TESTED USING ACTUAL PHOTOGRAPHS AND VARIOUS CONFIGURATIONS IN THE SELECTION OF CONTROL POINTS ON THE PHOTO. THE EFFECTS OF TILT AND ERROR PROPAGATION IN THIS PROCESS WERE ANALYZED. RECOMMENDATIONS ARE GIVEN REGARDING ACCURACY OF MEASUREMENTS, SELECTION OF STRONGEST POSSIBLE TRIANGULATION ARRANGEMENTS AND AREAS WHERE FUTURE RESEARCH IS DESIRABLE. /BPR/
