ines MN, NO, OP, are centerlines of a portion of a proposed highway. Respectively the bearings and distances are; MN due North, 277.60 meters; NO, N 26°40’ E, 107.00 meters, OP, N 61°30’ E, 200.00 meters. A previously designed compound curve connected these three tangent lines with the P.C.C at station 2+012.00. It is desired to revise the system into a single circular curve that will still be tangent to the three lines. Determine the following:                a.) Determine the radius of the simple curve                b.) Determine the stationing of the new P.C if station N is at 1+975.00.                c.) Determine the stationing of the new P.T.

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.
