Triangulation

A Triangulation system consists of a series of joined and overlapping triangles in which only one line (Base Line) is measured.All the angles are measured, and the remaining sides are calculated from angles.Knowing the true bearing of any one line, the bearings of all other lines can be calculated from the angles.The coordinates of all triangulation stations are then determined from the coordinates of any one given station.The vertices of the individual triangles are the triangulation stations.
