Difference Between Compass Surveying and Chain Surveying

Sl.No	Chain Surveying	Compass Surveying
1	Chain surveying employs chains and tapes for determining linear measurements.	Compass surveying employs a compass to determine angular measurements.
2	The frameworks consists of triangles whose sides are measured using chains or tapes.	The framework consists of series of connected lines. Whose angles are measured using compass and sides are measured using tapes or chains.
3	No angular measurements are done	Angular measurements are done along with simple linear measurements.
4	It is performed easily and the area is plotted easily.	It is difficult to perform compared to chain surveying and calculations are plotted with difficulty.
5	It requires tape corrections	This requires both tape corrections and compass corrections
6	Cheap	Expensive
7	Used for small and fairly levelled area	Used for large areas with rough ground having many details and undulations.
