1. The fixed point whose elevation is known, is called as

(a) benchmark
(b) reduced level
(c) station
(d) change point

Ans: (a) It is a fixed point of known elevation above the datum. Datum is the level surface (real or imaginary) used for reference.

2. Which of the following scales is the smallest one?

(a) 4:200000
(b) 1 cm = 5000 m
(c) 1 cm = 50 m
(d) RF=1/5000

Ans: (b)
4 : 2,000,00 = 1 : 50,000
1 cm : 5000 m = 1 cm : 5,000,00 cm
                          =1 : 500,000
1 cm : 50 m = 1 cm :5000 cm
                     =1 : 5000
RF = 1 : 5,000

3. When the curvature of earth is taken into account the surveying is called as

(a) Plain surveying
(b) Preliminary surveying
(c) Geodetic surveying
 (d) Hydrographic surveying

Ans: (c) Plane surveying: Mean surface of earth is considered as plane.
Geodetic surveying: Curvature af the earth is taken into account.

4. Ranging is defined as

 (a) measuring the distance from starting point
(b) establishing intermediate points on a chain line
(c) the distance between end points
(d) a point on a chain line

Ans: (b)  The process of locating intermediate points on survey line is known as ranging.

5. A line joining some fixed points on the main Survey lines is called as

 (a) Check Line
(b) tie line
(c) base line
(d) chain line

Ans: (b)
Check line: Line which is run to check the accuracy.
Tie line: Line which joins subsidiary or tie stations on the main line.
Base line: The largest of the main survey line is called as base line.

6. The main principle of field surveying is to work from

(a) higher level to lower level
(b) lower level to higher level
(c)part to whole
(d)whole to part

Ans: (d)
[SSC: JE: 2013]


 7. Offsets are

(a) lateral measurements from chain line
(b) Ties or check lines which are perpendicular to chain line
(c) Sets of minor measurements in chain
Surveying
(d) Chain lines which go out of alignments

Ans: (a)
Offsets are lateral measurements from base line to fix the position of different objects with respect to the base line

There are two types of offsets:
I) Perpendicular offset
II) Oblique offset

8. The fundamental principle of surveying is to work from the

(a)whole to part
(b) part to whole
(c) lower level to higher level
(d) higher level to lower level

Ans: (a)
Fundamental principles of surveying:
(i) Measuring distances rom two fixed points 

(ii) Working from whole to part

9. Which of the following statements in respect of a map A having scale 1:1000 and another map B having scale 1:5000 is true?

 (a) Map A is a large scale map compared to map B
(b) Map B is a large scale map compared to map A
(c) Map B is a more detailed map compared to map A
(d) None of the above

Ans: (a) Large scale maps are more detailed compared to small scale maps

10. The correction to be applied to each 30 m chain length for a line measurement along a slope of θ is

(a) 30(1- cosθ)
(b) 30(1- sinθ)
(c) 30(1- tanθ)
(d) 30(1- cotθ)

Ans: (a)

[SSC JE : 2014]

11. The magnetic declination is the distance between

(a) True meridian and false meridian
(b) False meridian and true meridian
(c) True meridian and magnetic meridian
 (d) Magnetic meridian and false meridian

Ans: (c)
Magnetic declination is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the earth's magnetic field lines) and true north (the direction along a meridian towards the geographic north pole). This angle varies depending on position on the Earth's surface, and changes with time.

12. The type of surveying which requires least office work is (least calculation):

(a) Theodolite surveying
(b) Tachometry
(c) Trigonometrical levelling
(d) Plane table surveying

Ans: (d) It allows the use of graphical methods rather than mathematical calculations.

13. When 10 cm on a map represents 10 m on the ground the representative fraction of the scale is:

(a) 1/10000
(b) 1/10
(c) 1/100
(d) 1/1000

Ans: (d)
