Control Survey and Geodetic reductions

Control surveys or survey controls are used to establish reference points as a basis for various construction activities. Vertical and horizontal control points are to be established in a control survey to increase accuracy. After establishing the control points, all other types of surveys such as topographic, right-of-way, aerial mapping, construction layout, boundary surveys, and utility mapping can be worked upon so that control networks can be formed. The place from which the observations are made is called a survey station.

Question

An EDM slope distance AB is determined to be 561.276 m. The EDM instrument is
1.820 m above station A, and the prism is 1.986 m above station B. The EDM in-
strument is mounted on a theodolite whose optical center is 1.720 m above the sta-
tion. The theodolite was used to measure the vertical angle (+6°21'38') to a target
on the prism pole; the target is 1.810 m above station B. Compute both the horizon-
tal distance AB and the elevation of station B if the elevation of station
A = 186.275 m.
