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.

A line of three-wire differential levels goes from benchmark Gloria to benchmark Carey. The length of the line was determined to be 2199 m. The instrument had a stated compensator accuracy of +0.3". The instrument-rod combination had an estimated reading error of +1 mm/km. The instrument is found to have an inclined collimation error of 1.0 mm/km, so the sight distances were kept to approximately 50 ± 5 m. If the difference in elevation observed is 15.601 m, what is the estimated error in the final elevation difference?
