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.

Topic: Civil Engineering Surveying "Horizontal Curves (Reverse Curves)"

A reverse curve with diverging tangents is to be design to
pass through three lines to form a center line of a
proposed road. The first line AB has a bearing of N 88° E
and a distance of 120 meters, BC has a bearing of N 62°
E and a distance of 340 meters, while that of CD has a
bearing of S 40° E and a distance of 230 meters. Compute
the total length of the reverse curve from the PC to PT if
the first tangent has a distance of 4 that of the common
tangent measured from the point of intersection of the
first curve.

Determining the relative position of points on the Earth's surface and measuring the angle and distance between them in order to calculate the required parameters such as elevation and enclosed area.
