5-) Plan-view sketches of benchmark leveling runs are shown in Figure. Along each line representing a sight is the value of the rod reading for that sight. The numbering of the TPs shows the direction of the level run. Place the data in the form of field notes (use Rise and Fall Method). Include the arithmetic check. Assuming that the average length of each BS and FS is 55 m, determine the accuracy of the survey. TP1 2.510 0.536 1.996 2.814 2-226 BM1 Elev: 19.015m 2ム? 0.827 BM2 1.656 3.089 2.636 TP3 TP2

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.
