Q.3) A map having a scale of 1 cm = 3 km, is represented as a RF as :
A) 1 : 3000
B) 1 : 30000
C) 1 : 300000
D) 1 : 3000000
Option (C)
Explanation :
Scale : 1 cm = 3 km
RF = 1 cm / 3 km = 1 / 3 x 1000 x 100
RF = 1 / 300000
hence, RF = 1 : 300000
Q.4) Surveys that are carried out to depict mountains, rivers, water bodies, wooden areas and other cultural details are known as :
A) Topographical surveys
B) Cadastral surveys
C) City surveys
D) Plane surveys
Option (A)
Explanation :
Topographical Surveys: Topographical surveys are a type of survey that captures and maps the physical features and characteristics of a piece of land, including its elevation, contours, vegetation, water bodies, and man-made structures. They are used to create accurate topographical maps and plans that can be used in engineering, construction, and land-use planning.
Cadastral Surveys : Cadastral survey is carried out to establish boundaries and legal ownership of land. It is used to create cadastral maps and plans that can be used for land registration, taxation, and other legal purposes.
City Survey : It is done to capture and map the physical features and characteristics of a city or urban area, including its buildings, roads, infrastructure, and natural features.
Plane Survey : Plane survey is done using planes or drones to capture large area of land. Typically, it is used create accurate maps and plans for large-scale projects, such as urban planning, environmental studies, and transportation infrastructure planning. In plane surveys, the curvature of earth is not taken.
Q.5) A Surveyor’s compass is used to determine :
A) Declination of a line
B) WCB of a line
C) Quadrantal bearing
D) Magnetic meridian
Option (C)
Explanation :
Nil.
Q.6) The lines passing through points at which the magnetic declination is equal at a given time are called :
A) Agonic lines
B) Isochrone lines
C) Isogonic lines
D) Isoclinic lines
Option (C)
Explanation :
Agonic lines : Lines joining the places of zero declination.
Isochrone lines : A line on a map that connects points where something happens or arrives at the same time.
Isogonic lines : Line joining the places of equal magnetic declination.
Isoclinic lines : Line sjoining the loci of the places having the same value of dip.
Q.7) If n is the number of sides, then the total sum of interior angles of a closed traverse should be –
A) 2n + 4
B) n + 2
C) 2n – 4
D) 4n – 2
Option (C)
Explanation :
Total sum of interior angles of a closed traverse = (2n – 4) x 900.
Sum of exterior angles of a closed traverse = (2n + 4) x 900.
n= no. of sides.

D) 0.0673 D2
Q.9) The imaginary line joining the center of diaphragm and the optical centre of the objective of a telescope is called :
A) Line of collimation
B) Axis of telescope
C) Line of sight
D) None of the above
Option (A)
Explanation :
Nil.
Q.10) Which of the following types of levelling cannot be done with a dumpy level?
A) Reciprocal levelling
B) Differential levelling
C) Profile levelling
D) Trigonometric levelling
Option (D)
Explanation :
Nil.
Q.11) The vertical distance between two adjacent contours is called :
A) Vertical equivalent
B) Contour gradient
C) Contour interval
D) None of the above
Option (C)
Explanation :
Nil.
Q.12) Which of the following technique is used for levelling across a river?
A) Trigonometric levelling
B) Reciprocal levelling
C) Cross levelling
D) Fly levelling
Option (B)
Explanation :
Reciprocal leveling is a surveying technique used to determine the difference in elevation between two points by measuring the height difference between two points in both directions, and then taking the average of the two readings.
It is done between two points widely separated in which observations are made in both directions to eliminate the effects of curvature of earth and atmospheric refraction. It is also used in geodetic surveys to establish accurate height benchmarks for mapping and other applications.
Q.13) Which of the following is carried out by the two theodolite method?
A) Tacheometric survey
B) Geodetic survey
C) Circular curve ranging
D) Astronomical survey
Option (C)

A) Vertical distance
B) Vertical angle
C) Horizontal angle
D) Both Horizontal and Vertical angle
Option (D)
Explanation :
Theodolite is used for measuring both horizontal and verticle angles.
Q.15) In aerial photogrammetry, the longitudinal overlap between two consecutive photographs is kept between ________.
A) 50% and 80%
B) 70% and 90%
C) 40% and 60%
