Local attraction in compass surveying may exist due to

Detailed Solution for Test: Compass Surveying & Theodolite - 1 - Question 2

Local attraction is a term used to denote any influence, which prevents the needle from pointing to the magnetic north in a given locality. Difference of fore bearing and back bearing = 0 ⇒ No local attraction.

Detailed Solution for Test: Compass Surveying & Theodolite - 1 - Question 6

Error due to eccentricity of inner and outer axes means that the centre of graduated horizontal circle does not coincide with the centre of vernier plate.

Test: Compass Surveying & Theodolite - 1 - Question 7

While measuring horizontal angles by the method of repetition with a theodolite, readings are taken on both the verniers. Which one of the following errors will be eliminated by reading both the verniers?

Test: Compass Surveying & Theodolite - 1 - Question 8

If the quadrantal bearing of a line is N25°W, then the whole circle bearing of the line is

Detailed Solution for Test: Compass Surveying & Theodolite - 1 - Question 8

Test: Compass Surveying & Theodolite - 1 - Question 9

The following bearings were observed while traversing with a compass:

Which stations were affected by local attraction?

Detailed Solution for Test: Compass Surveying & Theodolite - 1 - Question 9

As the difference between F.B and B.B of line AB is exactly 180°, stations A and B are free from local attraction which is not the case with line CD.
Hence stations C and D are affected by local attraction.

Test: Compass Surveying & Theodolite - 1 - Question 10

The coordinates of two end-points A and B of a traverse line AB are 
XA = 1000.00 m, YA = 10000.00 m
XB = 2000.00 m, YB = 1000.00 m 

The bearing of the line AB will be
