2) (i) To determine the elevation of the top of a chimney the following observations were made: Station Reading on B.M. Angle of elevation P 2.870 28°42′ Q 3.750 18°06' The top of the chimney and the stations P and Q are in the same vertical plane, PQ is 100 m. If the R.L. of the B.M. is 100.000 m, determine the elevation of the top of chimney. CO that show:

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.
