Control survey uses geodetic methods to establish widely spaced vertical and horizontal control points. It is created by rotating an ellipse around the shorter polar axis to match the Earth's actual shape. Establish the baseline, an accurately measured distance between 2 control points. Traversing and triangulation (measuring angles of triangles) are further discussed in this chapter. These are traditional methods to find coordinates of the stations and are time consuming. The baseline should occupy fairly level ground (< 5).
