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.

Problem 5 a. The observed compass bearing of a line in 1981 was S. 37°30' E. and the magnetic declination of the place then was known to be 3°10' W. It has also discovered that during the observation local attraction of the place at that moment of 5°E existed. Find the true azimuth of the line. b. The bearing of a line from A to B was measured as S. 16°30' W. It was found that there was local attraction at both A and B and therefore a forward and a backward bearing were taken between A and a point C at which there was no local attraction. If the bearing of AC was S.30°10' E. and that of CA was N. 28°20' W., what is the corrected bearing of AB? c.
