Determine the clearance or obstruction of the line of sight at hill B if the observer is at A so that C will be visible from A. b. If C is not visible from A, what height of tower must be constructed at C so that it could be visible from A with the line of sight having a clearance of 2m above the hill B. c. What height of equal towers at A and C must be constructed in order that A,B and C will be indivisible?

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.
