Fundamental Concepts of Surveying

Compass surveying is a type of surveying in which the directions of surveying lines are determined with a magnetic compass, and the length of the surveying lines are measured with a tape or chain or laser rangefinder. The compass is generally used to run a traverse line. Compass surveying can be defined as the method of surveying in which the directions of the survey lines is determined by means of a compass and also by using tape or a chain. This measurement is directly done on the surface of the Earth. 
Mainly the compass surveying method makes use of a compass to carry out the angular measurements. The compass surveying procedure is done through traversing.
Magnetic Compass in Compass Surveying

The magnetic meridian is the basis on which the magnetic compass measures the directions. This will require the magnetized needle, a line of sight and a graduated circle.
