A backsight is taken on a benchmark of elevation 500 m, rod reading of 1.75 meters, vertical angle of + 30⁰00’, and slope distance of 76 m from the instrument. A foresight is taken on a point A with rod reading of 1.25 m., vertical angle of 45⁰ 49’ 53”, and a slope distance of 52.28 m from the instrument. If the height of instrument is 1.20 m., determine the elevation of point A.

Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.
