A 50-m steel tape weighing 2.42kg is of standard length under a pull of 13kg, supported for full length. The tape was used in measuring a line 837.65m on a smooth level ground under a steady pull of 18kg. Assuming E = 2.0 x10^6kg/cm² and the unit weight of steel to be 7.9 x 10^-3 kg/cm³. Determine the correct length of the line measured.

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.
