Leveling and Contouring

Q.1. An imaginary line lying throughout the surface of ground and preserving a constant inclination to the horizontal is known as

a) contour line

b) horizontal equivalent

c) contour interval

d) contour gradient ✔

Q.2. A series of closely spaced contour lines represents a

a) steep slope ✔

b) gentle slope

c) uniform slope

d) plane surface

Q.3. Direct method of contouring is

a) a quick method

b) adopted for large surveys only

c) most accurate method ✔

d) suitable for hilly terrains

Q.4. Which of the following methods of contouring is most suitable for a hilly terrain ?

a) direct method

b) square method

c) cross-sections method

d) tacheometric method ✔

Q.5. Closed contours, with higher value inwards, represent a

a) depression

b) hillock ✔

c) plain surface

d) none of the above

Q.6. Contour interval is

a) the vertical distance between two consecutive contours ✔

b) the horizontal distance between two consecutive contours

c) the vertical distance between two points on same contour

d) the horizontal distance between two points on same contour

Q.7. Benchmark is established by

a) hypsometry

b) barometric leveling

c) spirit leveling ✔

d) trigonometrical leveling

Q.8. How many methods are used in levelling?

a) 3

b) 2 ✔

c) 4

d) 5

The two methods are the height of instrument method and rise and fall method.

Q.9. In_______ leveling, the first and last point are at a far distance.

a) Fly

b) Differential ✔

c) Profile

d) Reciprocal

Q.10. The last reading taken from the instrument is called

a) End sight

b) Intermediate sight

c) Fore sight ✔

d) Back sight

Fore sight (FS) is noted as last reading, back sight (BS) is noted as first reading taken from the instrument and Any intermediate points are noted down as intermediate sight (IS).

Q.11. The line of collimation method of reduce leveling, does not provide check on

a) Reduced levels

b) Intermediate sight ✔

c) Fore sight

d) Back sight

Q.12. In a hilly terrain, staff reading is more at

a) Lower point ✔

b) Higher point

c) First point

d) Last point

Q.13. Which is the arithmetic check for the height of instrument method?

a) ∑FS + ∑BS = First RL + Last RL

b) ∑BS – ∑FS = Last RL – First RL ✔

c) ∑BS – ∑FS = Last RL – First RL = ∑Rise  - ∑Fall

d) ∑BS + ∑FS = Last RL +First RL = ∑Rise +∑Fall

Q.14. Which instrument is used in trigonometric leveling?

a) Wye level

b) Compass

c) Theodolite ✔

d) Dumpy level

Q.15. In leveling, error due to earth’s curvature is to be corrected using

a)  

b) 

c) 

d)  ✔
