The interior angle of a six sided closed traverse were measured as follows: A=96°16', B=135°28', C=214°52', D= Not Measured, E = 121°21' and F= 114°20', If all observed angles are assumed to be correct, determine the interior angle of D, also, determine the bearing of each line if the bearing of line AB is S 55°21' E. Tabulate values accordingly and sketch the traverse.

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.
