Q-9: A road is to be constructed with a uniform rising gradient of 1 in 100. Determine the staff reading required for setting the tops of the two pegs on the given gradient at 30 meters interval from the last position of the instrument. The RL of the first peg is 384.500 m. A fly levelling was carried out from a BM of RL 387.000 m. The following observations (in m) were recorded. Backsight: 1.625 2.345 2.045 2.955 Foresight: 1.315 3.560 2.355 af levol fro

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.
