How To Calculate True Bearing From Magnetic Bearing – || Rules and Example||

Calculate True Bearing From Magnetic Bearing If the magnetic declination at a place at the time of observation is known, the true bearing of a line can be calculated from its magnetic bearing and vice-versa. Determination of True Bearing From Magnetic Bearing Rules The following rules are applied to determine the true bearing if the …

Convert The Whole Circle Bearing to Reduced Bearing – || Rules and Example ||

Convert Whole Circle Bearing to Reduced Bearing Rules 1. When Whole Circle Bearing(W.C.B) lies between 0° to 90°.  Reduced Bearing(R.B) = W.C.B 2. When W.C.B lies between 90° to 180°. R.B = (180° – W.C.B) 3. When W.C.B lies between 180° to 270°. R.B = (W.C.B – 180°) 4. When Whole Circle Bearing(W.C.B) lies between 270° to 360°. Reduced Bearing(R.B) = (360° – W.C.B) Example …
