Question
2. The following data were obtained by stadia observation; vertical angle, +12 deg 30
min; upper stadia hair reading and lower stadia hair readings, 4.5 and 3.25m,
respectively. The rod reading was taken at 3.875m above the stadia point at A. and the
height of the instrument above the instrument station B, is 1.620m. If the stadia interval
factor is 99.5 and the instrument constant is0.381m, find
a) the horizontal distance between the instrument station and the stadia point.
b) The inclined distance from the center of the instrument to the rod reading
c) The difference in elevation between the two ground point.
