SUPER-WIDE-ANGLE PHOTOGRAPHY AND ITS APPLICATION IN HIGHWAY MAPPING

SUPERWIDE ANGLE PHOTOGRAPHY HAS BEEN USED SUCCESSFULLY IN SMALL AND MEDIUM SCALE MAPPING; THIS STUDY WAS UNDERTAKEN TO EVALUATE SUPERWIDE-ANGLE PHOTOGRAPHY FOR LARGE SCALE MAPPING /HIGHWAY MAPPING/. ONE ASPECT OF THE EVALUATION WAS TO ESTABLISH TEST PROCEDURES AND THEN TEST THE PROCEDURES UTILIZING FIRST ORDER STEREOPLOTTERS WITH SPECIAL REFERENCE TO THE ANALYTICAL STEREOPLOTTER, AP/C. THE EVALUATION ALSO INCLUDED COMPARISON OF THE SUPERWIDE-ANGLE SYSTEM TO THE STANDARD WIDE-ANGLE SYSTEM. ESTABLISHED TEST PROCEDURES INVOLVED INTERIOR ORIENTATION, FILM DISTORTION, CALIBRATION OF FIDUCIAL SYSTEM, CORRECTION FOR FILM DISTORTION, LENS DISTORTION, EARTH CURVATURE, ATMOSPHORIC REFRACTION, CORRECTOR PLATES, RELATIVE ORIENTATION AND ABSOLUTE ORIENTATION. TESTING THE PROCEDURES INVOLVED PROCESSING AN AEROTRIANGULATION PROBLEM WITH PHOTOGRAPHS OF A CONTROLLED TEST AREA. RESULTS OBTAINED FROM AP/C WERE COMPARED WITH RESULTS FROM THE ANALOGUE STEREOPLOTTER /WILD A7/. DOCUMENTATION FOR THE CALIBRATION PROCEDURES FOR INTERIOR ORIENTATION, FORMULAS FOR ABSOLUTE ORIENTATION, LINEAR TRANSFORMATION OF STRIP COORDINATES, STRIP ADJUSTMENT, FORMULAS AND COMPUTER COEFFICIENTS FOR RELATIVE ORIENTATION ARE PRESENTED IN THE APPENDIX OF THE REPORT. THE CONCLUSIONS INDICATE THE TESTS EXCEEDED EXPECTATIONS. HOWEVER, BECAUSE OF THE LIMITED SCOPE AND SIZE OF THE TEST, THE RESULTS SHOULD NOT BE USED FOR PLANNING PURPOSES. THE REPORT PRESENTS SEVERAL STRONG RECOMMENDATIONS FOR THE CONTINUING STUDY OF THE SUBJECT MATTER. /BPR/
