A simple curve has a central angle of 60°. The stationing of the point of curvature is equal to 5 + 900. The offset distance from the station PT to the tangent line passing thru the PC is 108 meter long. Determine: a) the stationing of a point A on the curve if it forms a deflection angle from the tangent at PC equal to 20°.

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.
