Basic Surveying - Theory and Practice : Bearings

Bearings 

The bearing of a line also gives the direction of a line with respect to the 
reference meridian.  The bearing states whether the angle is measured 
from the north or the south and also whether the angle is measured 
toward the east or west.  For example, if a line has a bearing of S 47° E, 
the bearing angle 47° is measured from the south meridian eastward. 
A stated bearing is said to be a true bearing, a magnetic bearing, an 
assumed bearing, or a grid bearing, according to the type of meridian 
referenced.
