Summary: compass surveying Bearing(Angle)-two types of bearing for a particular lines 1.Fore bearing (FB) 2.Back bearing (BB) therefore FB180 degree BB=FB-180 degree BB180 degree FB=BB-180degree Whole circle Bearing (WCB): Concept of a)True Bearing (TB) b)Magnetic bearing (MM) Angle b/w True Meridian (TM) & Magnetic Meridian(MM) is called Declination (D) Important point: TB=MB+D(East) TB=MB-D(West) Note: Difference b/w FB & BB is 180 degree - No local attraction error Error= measured value - Actual value Home work: 1.ans =C 2.ans=D thanks a lot sir looking forward to more sessions.

[@surbhisingh8926]

Home work: 1. Ans =C 2. Ans=D

Traversing?

[@souravshree9517]

Summary : Bearing (Angle): 2 types of bearing for a line. 1.Fore bearing (FB) 2.Back bearing (BB) FB180 degree BB=FB-180 deg BB180 deg FB=BB-180 deg Whole circle Bearing (WCB): Taken from North , upto 360 deg RB or QB : Taken from South or North Bearing: Angle corresponding to Meridian. 1. True Bearing (TB) 2. Magnetic bearing (MB) Angle between True Meridian (TM) and Magnetic Meridian(MM) is Declination (D). Important point: TB = MB+D ( Eastern D ) TB = MB-D ( Western D ) Note: Difference between FB & BB is 180 degree : No local attraction error Error= measured value - Actual Home work: 1. Answer : C 2. Answer : D The session was very helpful for all exams. My doubt about Local attraction was cleared in such a wonderful manner. Thank you very much sir.
