differential levelling

flying levelling

Q4 | The horizontal angle between true meridian and magnetic meridian, is known

bearing

looking at an isolated point not on the line

establishing an intermediate point on the line

determining the distance between end points

determining the offset distance

Q6 | Reduced bearing of a line is an angle between

north line and given line measured clockwise

north line and given line measured anticlockwise

east or west and the given line

given line and the part of the meridian whether N end or S end, lying adjacent to it.

magnetic needle

and properly balanced magnetic needle

properly balanced and uninfluenced by local attractive force

magnetic needle over an iron pivot.
