When the base of the object is inaccessible we use an indirect method of surveying.
A tachometer is used to measure the distance between the two points with the use of an analytical lens. There are two methods
D=(f/L)S + (f + d)
D=horizontal distance between tachometer and stadia rod.
f/L = multiplying constant
S= Staff Intercept
Elevation formula:
v = KSsin(2©)/2 + Ccos(2©)
© = Theta= Angle of elevation or depression.
K & C = Tachometric Constant
substance method and tangential method is also used to find the elevation between two points.
