art 2. If a level is being used to determine the elevation of the unknown as shown from a known BM (Elev = 1806.66 ft). The autoleve is set up directly between the known and unknown with the distance to each marker of d = 176. If the auto level is leveled correctly with a B.S. = 3.47 ft. and F.S. = 7.10 ft. the elevation of the unknown is 1803.03 ft. What is the elevation of the unknown if the auto level is then bumped and accidentally tilted 1.3°?

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.
