From the distances and deflections computed in Problem 13.8, compute the three key chord layout lengths: (1) the BC to the first 100-ft station, (2) the chord distance for 100-ft (arc) stations, and (3) from the last even 100-ft station to the EC.   This is 13.8 Given PI at 15 + 78.28, Δ = 36°10′30″RT, and R = 1,150 ft, compute the deflections for even 100-ft stations.

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.
