The instrument with an interior focusing telescope was set at point A of elevation 12 m. With the height of the instrument of 1.35 m. Point B was sighted at an angle of 20 degrees with a rod reading of 3.20 m and 0.55 m for the upper and lower cross hair respectively. During measurement, the 5m rod was held inclined towards the rodman with top offset of 0.18 m. Assume k = 100. a) Draw the sketch based on the given problem. b) Determine the horizontal and vertical stadia distance and elevation of Point B.

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.
