In a terrestrial ph@.Q,,g1mmetric survey, a photo theodolits was set up over two station A and
B running from we$t,,,toreast at the extreme points of-a base line AB measuring 1300m in
length. The optical axds:dphototheodolites at A an&;B are inclined inwards at angles 50"
and 46 at base line. The N;l;.frorn A shows lpp+qt D 24nln to the left of the vertical line
and 6mm above the horizontal&% while in.p.1. graph from B, it was 30mm to the left of
the vertical line. Focal length of'C#npp leris*rs 30cm and R.L. of camera axis at A is 60.12
