Download Solution PDFConcept:
Slope, temperature, and tension corrections are required in chain surveying, not in Tacheometric surveying.
In Method of Tacheometry
In this figure, the Line of sight is horizontal and staff is held truly vertical.
Tacheometric distance formula
D = KS + C
Where,
K is (f/i) → called a multiplying constant
C is (f + d) → called an additive constant
As
f = focal length of the lens, i = stadia hair interval
Calculations:
k = 100, S = 2.5
D = 2.5 × 100 = 250 m
