Whole Circle Bearing and Quadrantal Bearing (Reduced Bearing) are two different types of bearing measurement used in surveying. To choose between these two types of bearing measurement a surveyor must know the differences between them. The main differences between Whole Circle Bearing and Quadrantal Bearing (Reduced Bearing) are given below.
|Whole Circle Bearing||Quadrantal Bearing/Reduced Bearing|
|1|| || |
|2||Only the magnetic north line is considered as reference line in whole circle bearing system.||Both magnetic north and south lines are considered as reference line in quadrantal bearing system.|
|3||The cloclwise angle from the reference line is Only taken||Both cloclwise and anticloclwise angle from the reference line is Only taken|
|4||The value of the whole circle bearing varies from 0° to 360°||The value of the reduced bearing varies from 0° to 90°|
|5||Example: 26°, 121°, 245°, 350° etc.||Example: N26°E, S59°E, S65°W, N10°W etc.|
