Fore bearing : The bearing of line observed in the direction of progress of survey is called fore bearing of the line. Bearing of line AB is observed at ‘A’ towards ‘B’ is called as fore bearing of the line ‘AB ‘

Back bearing : The bearing of line observed in opposite direction of the progress of survey is called back bearing of the line. The bearing observed at ‘B’ towards ‘A’ is called as back bearing of the line ‘AB’
