DETERMINATION OF POSITION WITH INTERSECTING CIRCLES

THE INTERSECTING CIRCLE TECHNIQUE FOR DETERMINATION OF POSITION CAN RESULT IN GREAT SAVINGS IN TIME AND EQUIPMENT. USUALLY ONLY ONE ASSISTANT IS NEEDED AND CONCEIVABLY THE PROCESS COULD BE PERFORMED SINGLE-HANDEDLY, ESPECIALLY IF NATURAL SIGHTS OF KNOWN POSITION ARE AVAILABLE. IN MANY SITUATIONS, NO LINEAR MEASUREMENTS ARE NEEDED, THUS ELIMINATING THE NEED FOR EXPENSIVE ELECTRONIC MEASURING INSTRUEMTS. THE ACCURACY OF POSITION, DETERMINED WITH INTERSECTING CIRCLES, IS COMPARABLE TO CONVENTIONAL TRAVERSING RESULTS, EVEN WHEN NO LINEAR MEASUREMENTS ARE MADE. BY ROUGHLY PLOTTING THE COORDINATE POSITIONS OF THE INVOLVED POINTS AND VISUALLY INSPECTING THE INTERSECTION ANGLES BETWEEN CIRCLES, AN ANALYSIS OF "STRENGTH OF FIGURE CAN BE EASILY MADE GRAPHICALLY." A "FLAT" INTERSECTION ANGLE WOULD OBVIOUSLY BE GIVEN LESS WEIGHT THAN A "STRONG" ONE. THE BEAUTY OF THE INTERSECTING CIRCLE METHOD IS THAT ONE MAN WITH A RELIABLE TRANSIT OR THEODOLITE CAN GET AS GOOD RESULTS, IN MANY SITUATIONS, AS A FULLY EQUIPPED SURVEY CREW USING EXPENSIVE ELECTRONIC INSTRUMENTS. /AUTHOR/
