Day 6 - Surveying

The zero of the graduated circle of a prismatic compass is located a

The latitude of an traverse line is obtained by the product of length and

…..meridian of a place changes its position with time

Magnetic bearing of survey lines at any place

The line in which plane passing through the given point and the north and south poles intersects the surface of the earth is called

The convenient direction assumed as a meridian for measuring bearing of survey lines is known as

The horizontal angle between the north meridian and the line measured clockwise is known as

The circle of contact of earth and the cone of visual rays passing through the point of observation is called

Imaginary line passing through points having equal magnetic declination is termed as

Which among the following is the back bearing of N 30 E

The needle of the magnetic compass is generallty supported on a
