###### Question details

A total station was set between two points (A and B) to get
the elevation of the point B. The elevation of the point A
(benchmark, BM) is known as 50.000 m. A surveyor obtained a reading
of 2.125 m from the rod at the point A, and a slope distance of 200
m and the zenith angle of 98° 15’ 30’’ to the rod, and then the
surveyor rotated the total station to target the rod placed at the
point B. The reading from the rod at the point B was 0.875 m, the
distance reading from the total station was 350 m, and the nadir
angle to the rod at point B was 100° 20’ 10’’. Find the elevation
of the point B with curvature and refraction corrections if
needed.
