Layout a simple curve with tangents at point A and B respectively. The line from point A and the intersection of the tangents has a bearing and distance of N65°00’E and 30.50 meters respectively. If the bearing of point B from the point of intersection of the tangents is S 47°00' E, determine the length of the curve.

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.
