Compass surveying

The imaginary line connecting with north and south pole of earth known as

• Assumed meridian

• True meridian

• Magnetic meridian

• Bearing

Broad form of needle used in

• Prismatic compass

• Surveyors compass

• Trough compass

• None of these

The graduations in a prismatic compass is

• Have zero at south

• Inverted

• 0 - 360 degree

• All of the above

The 360 degree or 0 degree of the graduation is marked at the.....

End of the graduated circle in prismatic compass

• N

• E

• S

• W

In which system, the bearing of a line is measured with magnetic north in clock wise direction

• Quadrantal bearing system

• Reduced bearing system

• Magnetic bearing system

• Whole circle bearing system

The anti clockwise traverse MNOP is square. Forebearing of line MN = 290 degree then the back bearing of line PM is

• 290 degree

• 110 degree

• 200 degree

• 20 degree

If the WCB of a line is 270 degree, it's RB is

• A. S90deg W

• B. N 90deg W

• C. S90 degE

• Both A and B

The variation of magnetic declination within day is called

• Annual variation

• Irregular variation

• Diurnal variation

• Secular variation

If WCB of the line is in between 180 deg and 270 deg it's reduced bearing is equal to..... and the quadrant is......

• 180 deg, SW

• 180 degree ,SE

• 270 deg, NE

• None

The magnetic bearingbof a line AB is 212 degree 30 min and the declination is 2 degree 15 min east. What is the true bearing of the line

• 210 deg 15 min

• 214 deg 45min

• 210 degree 45 min

• 132 degree 30 min
