Area-Computation-&-Tacheometric-Surveying

Stadia readings were taken with a odolite on a vertical staff with telescope inclined at an angle of depression of 3o30′. The staff readings were 2.990, 2.055 and 1.120. The reduced level of staff station is 100.000m, and height of instrument is 1.40 m. What is reduced level of ground at instrument? Take constants as 100 and zero.

A tacheometer is setup at an intermediate point on a traverse course PQ and the following observations are made on a staff held vertical. Staff Station Vertical Angle Staff Intercept Axial Hair Readings P + 9o30′ 2.250 2.105 Q + 6o00′ 2.055 1.975 The constants are 100 and 0. Compute the length PQ and the reduced level of Q. RL of P = 350.50 m.
