Triangulation Method of Traversing

In construction field we do traversing in 3 methods-Coordinate method,Angle and distance method and Triangulation method.In traversing , the framework consisted of a number of connected line .the length are measure by chain or tape and the directions identified by angle measurement instrument compass.

Triangulation Method of Traversing

In surveying ,the area to be surveyed is divided into a number of triangles .this method is suitable for fairly level ground covering small area .But when the area is large , undulating and crowded with many details triangulation (which is the principle of survey ) is not possible . In such in area , the method of traversing is adopted.

In traversing , the framework consisted of a number of connected line .the length are measure by chain or tape and the directions identified by angle measurement instrument compass. But now a day we are use a good accuracy Total Station instrument for doing traversing, topographic survey,setting out and many more survey related activity.Remember always do traverse in an anticlockwise direction of survey lines.In construction field we do traversing in 3 methods.

Co-ordinate method.
Angle and distance method.
Triangulation method

Triangulation Method of Traversing

Coordinate Method :-

In coordinate method we started from two known point with imputing coordinate of station point and backside and doing traversing in an anticlockwise,continue to fixed new point in traversing and at-last closed a known point. Usually we use it in low accuracy projects like road project canal project.

Angle and Distance Method :-

In angle distance method we started from two known point but not impute coordinate of station point and backside only take interior angle,exterior angle and distance,continue to fixed new point in traversing and at-last closed a known point.This a good accuracy method of traversing Usually we use it in bridge project , power plant project and many others accuracy projects.
