TWO METHODS OF ANALYTIC TRIANGULATION FOR HIGHWAYS

THE RESULTS OF A COMPARISON OF TWO METHODS OF ANALYTIC AERIAL TRIANGULATION ARE GIVEN. THE EVALUATION WAS PERFORMED WITH 1:4,800- AND 1:9,600-SCALE PHOTOGRAPHS. THE STRIP COORDINATE COMPUTATIONS AND STRIP ADJUSTMENTS FOR THE CANADIAN NATIONAL RESEARCH COUNCIL AND U. S. COAST AND GEODETIC SURVEY METHODS WERE TESTED USING THE SAME MEASURED PLATE COORDINATES AND GROUND CONTROL. SECOND DEGREE POLYNOMIALS IN BOTH METHODS GAVE BETTER OVERALL RESULTS. ALTHOUGH THE ERROR PROPAGATION WITHIN EACH STRIP COMPUTATION WAS UNDOUBTEDLY DIFFERENT, THE RESULTING COMPUTED GROUND COORDINATES ARE NOT SIGNIFICANTLY AFFECTED. /PE/
