QUESTION: 1

### A series of closely spaced contour lines represents a

Solution:

Closed contours ⇒ Steep slope
Apart contour lines ⇒ Gentle slope
Equally spaced ⇒ Uniform slope Straight parallel and equally speed contours ⇒ plane surface

QUESTION: 2

### In order to measure the magnetic bearing of a line, the theodolite should be provided with ______

Solution:

In order to measure the magnetic bearing of a line, the theodolite should be provided with either a tabular compass or trough compass.

QUESTION: 3

### Closed contours, with higher value inwards, represent a

Solution:
QUESTION: 4

The Bowditch method of adjusting a traverse is based on the assumption that

where e1 and e2 are errors in linear and angular measurements respectively and l is the length of a line

Solution:
QUESTION: 5

Accuracy of elevation of various points obtained from contour map is limited to

Solution:
QUESTION: 6

If L is the perimeter of a closed traverse, ΔD is the closing error in departure, the correction for the departure of a traverse side of length l, according to Bowditch rule, is

Solution:

Bowditch’s method - Correction to latitude (or departure) of any side

QUESTION: 7

If arithmetic sum of latitudes of a closed traverse is ∑Lat and closing error in latitude is dx, the correction for a side whose latitude is l, as given by Transit Rule, is

Solution:

Transit method -→ Correction of latitude (and departure) of any side

QUESTION: 8

If the reduced bearing of a line AB is N60°W and length is 100 m, then the latitude and departure respectively of the line AB will be

Solution:
QUESTION: 9

If the sum of northings of a traverse exceeds the sum of southings by 1 m and sum of eastings exceeds the sum of westirigs by 1 m, the resultant closing error and its true bearing respectively are

Solution:
QUESTION: 10

In a closed traverse, the sum of south latitudes exceeds the sum of north latitudes and the sum of east departures exceeds the sum of west departures. The closing line will lie in the

Solution:

The closing line will have south latitude and east departure. Therefore it will lie in S-E quadrant.
