The study of this training manual will enable you to understand the underlying theory of surveying, the instruments and their uses, and the surveying methods. Types of Meridians: •Magnetic meridian :- The direction shown by a freely suspended needle which is magnetised and balanced properly without influenced by other factors is known as magnetic meridian •True meridian :- True meridian is the line which passage through the true north and south. We are a locally owned company and our top priority is customer care. Meridian lines are used as one of the reference points (coordinates) with baselines in land surveying grid system to locate any point on earth. What is Traversing Surveying?

They are used for topographic, Hydrographic, cadastral, project and construction surveys. What is Traversing Surveying? It is also called geographic meridian. ... For example, the datum-level for elevation is typically taken as mean sea level. Also called longitude. Compass surveying is done by using traversing. From these definitions it follows that if there were a star exactly at the pole it would only be necessary to set up an instrument and take a bearing to it for the meridian.
