the relative accuracy (in nearest 100 ft) of a given traverse of 50,000 ft that failed to close by 0.25 ft in the northing and 0.50 ft in the easting is 1:89,400. Solution 1. Use the closing error formula e = [?L 2 +?D 2 ] ½ Where L = latitude = northing = 0.5 ft D = departure = easting = 0.25 ft e = [(.5) 2 +(.25)2] ½ = 0.559 2. Use the accuracy ratio formula. Accuracy = radial error of closure/total length of the traverse Accuracy = 0.559 / 50000 = 1:89,443
