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.

Question

1. A student counted 36, 35, 36, 38, 35, and 36 paces in six trials of walking along a course
of 25m known length on level ground. Then 27, 28, 26, and 27 paces were counted in
walking four repetitions of an unknown distance AB. What is (a) the pace length and (b)
the length of AB?
