Instrumental method:-

>PROCESS:- Set the theodolite at O, leveled the instrument used plate level and altitude level. Measured the distance QR with the chain or tape. The angle of elevation A and angle of depression B also measure. Let the distance OR = D. Then use the tan formula.

h2 = D* TAN A

h3=D*TAN B

Total height of the PR : h2+h3

RL OF P= BM+h1+h2

RL OF Q= BM+h1-h2

In the nowadays height of an object also determined by the use of TOTAL STATION, DRONE SURVEY, etc.
