As per plan, the distance between two telephone poles is 4350.35 meters. If the location of one is known in the field and the second is to be laid with a 30 m tape known to be 0.02 meter too short, along an average ground slope of 1.2%. Determine the actual length to be laid along the ground surface.

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.
