The figure shown below provides the rod readings in the order in which they were taken. The elevation of the starting Benchmark (BM) A is shown. The last reading is taken at another benchmark known as BM B which has an elevation of 92.50 ft. Based on the information given, What is the elevation of BM B and the Error of Closure (EC) for the differential leveling shown? FS= 4.20 BRI BS= 2.50 TP 1 BM A BS=1.30 Elev. = 100.00 O BM B= 92.50 ft; EC = 0.02 ft. BM B= 92.50 ft; EC = 0 ft. O BM B= 92.48 ft; EC = 0.02 ft. O BM B= 92.48 ft; EC = 0 ft. FS= 7.12 BM B

Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.
