1.
The primary object of surveying is to:
a)
Determine relative heights of points
b)
Establish control stations
c)
Prepare a plan or map of an area
d)
Measure vertical angles
2.
Levelling is mainly concerned with measurements in the:
a)
Horizontal plane
b)
Vertical plane
c)
Inclined plane
d)
Curved surface of the earth
3.
Which of the following correctly distinguishes a plan from a map?
a)
Plan covers a large area at small scale
b)
Map covers a small area at large scale
c)
Plan is drawn to a large scale covering a small area
d)
Map shows more details than a plan
4.
Which surveying method assumes the earth surface to be flat?
a)
Geodetic survey
b)
Trigonometrical survey
c)
Plane survey
d)
Astronomical survey
5.
Geodetic surveying differs from plane surveying because it:
a)
Uses chain and compass
b)
Is limited to small areas
c)
Considers curvature of the earth
d)
Uses only linear measurements
6.
Plane surveying should be replaced by geodetic surveying when the area exceeds approximately:
a)
100 km2
b)
150 km2
c)
260 km2
d)
500 km2
7.
The difference between arc length and chord length for a distance of about 18.2 km is approximately:
a)
1 cm
b)
5 cm
c)
10 cm
d)
50 cm
8.
The sum of the angles of a spherical triangle is:
a)
Always less than 180 degrees
b)
Exactly equal to 180 degrees
c)
Greater than 180 degrees
d)
Independent of area
9.
Assertion: In geodetic surveying the sum of angles of a triangle is greater than 180 degrees Reason: The curvature of the earth is taken into account
a)
Both A and R are true and R explains A
b)
Both A and R are true but R does not explain A
c)
A is true but R is false
d)
A is false but R is true
10.
Assertion: The primary object of geodetic surveying is to prepare a detailed plan of a small area Reason: Geodetic surveying establishes highly accurate control points over large areas
a)
Both A and R are true and R explains A
b)
Both A and R are true but R does not explain A
c)
A is true but R is false
d)
A is false but R is true
