Explain four types of meridians. 
by

1 Answer

Answer :

1. True meridian: -The line which is passing through geographical north or south pole and given point on the surface of earth is called as true meridian. 2. Magnetic meridian:-The direction indicated by a freely suspended and properly balanced magnetic needle unaffected by local attractive forces is called as magnetic meridian. 3. Arbitrary meridian:- For small project any convenient direction may be taken as arbitrary meridian. 4. Grid meridian:- Sometimes, for preparing a map some state agencies assume several lines parallel to true meridian for a particular zone. These lines are termed as grid lines and the centre line as the grid meridian.
