Understanding Fore Bearing and Back Bearing



First of all, getting into work Land Surveyor must understand the concept of Fore Bearing and Back Bearing.
Suppose we have 2 stations A & B,
Occupy Station A and see towards Station B,

Concept -1


Here in the Picture Bearing of 2° is the Fore Bearing of Point A
While Staying at Station A
Occupy Station A again and see towards Station B,



Concept -2


Here in the Picture Bearing of 2°+180° =182° is the Back Bearing of Point A While Staying at Station A
Now Suppose we have 2 stations A & B,

Occupy Station B and see towards Station A,

Concept -3


Here in the Picture Bearing of 182° is the Fore Bearing of Point B
While Staying at Station B
Occupy Station B and see towards Station A,



Concept -4


Here in the Picture Bearing of 182°+180° =362°-360°=2° is the Back Bearing of Point B
Because 362° is more than a circle you need to deduct 360° from this, result will be 2°
This is the Basic Concept of Fore Bearing and back Bearing
