In the past it was difficult to accurately measure very long distances, but it was possible to accurately measure the angles between points many kilometres apart, limited only by being able to see the distant beacon.

Reestablishment of the boundary between the United States and Canada. Triangulation Definition. The horizontal control in Geodetic survey is established either by triangulation or by precise traverse.

In triangulation, the system consists of a number of inter-connected triangles in which the length of only one line is called the base line and the angles of the triangle are measured very precisely. sketch (including, at min.: north arrow, scale or indicate not to scale, use straight edge for lines, adequate information to show the location of work) your signature indication of whether the notes are original or a copy Your final grade in this class is largely based on the quality, completeness and correctness of your field Size: 2MB.

establishing a triangulation system to maintain the computations within a desired degree of precision. For a given change in the angles, the sine of small angles change more rapidly than those of large angles. This suggests that smaller angles less than 30° should not be used in the computation of Size: KB.

An observer at A measures the angle α, while the observer at B measures β.(remember that in triangulation only one angle is measured).

The position of any vertex of a triangle can be calculated if the position of one side, and two angles, are known. • Such provision of control point can be made either one• Such provision of control point can be made either one or combination of both the following methods 1.

Traverse 2. Triangulation Triangulation is considered to be more accurate than traversing as there is less accumulation of errors than that in traverse.

Triangulation involves using multiple data sources in an investigation to produce understanding. Some see triangulation as a method for corroborating findings and as a test for validity. This, however, is controversial.

This assumes that a weakness in one method will be compensated for by another method, and that it is always possible to make.
