The top of the tower signal at B, 2000m away from A was sighted through a transit with a recorded vertical angle of +3°30'. The height of the tower is 12m and the H.I. of the transit above point where it is set is 1.10m. 1. Determine the difference in Elevation between A and B. 2. If the elevation of the point under the transit at A is 133.33m. Compute the elevation of the base of the tower at B. 3. How high is the base of the tower to the base of the transit?

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.
