What is compass surveying?

In traversing, when the compass is used for the angular measurements then it is called compass traversing or compass surveying.

In this process of surveying, the compass is used to determine the direction of the survey line of the boundary work of the traverse by measuring the angles. The lines make angles with the magnetic meridian. The process of chaining and offsetting is similar to chain surveying and running of check line is not required.

The compass surveying is suitable under the following situation:

1. when the survey details are required with the long narrow strips that is a road, railway, etc.
2. When the area can not be divided into triangles for surveying.
3. When the ground is too large
4. When the long straight line cannot be sighted or accountable due to the obstacles.
5. When the surveying is done in dense areas like hilly areas or jungles.
6. The compass surveying is not suitable for areas where the places abounding in magnetic rock or iron. It can be done quickly but is less accurate than theodolite traversing.
7. It can be used for military purposes.
