1. Representing large scale on the surface of the earth is____________
a) Plan
b) Map
c) Scale
d) Area
Explanation: For any representation, if it consists large scale then it represents plan and for small scale it represents map.
2. The ratio of map distance to corresponding ground distance is called as__________
a) Representative factor
b) Representation factor
c) Reciprocating factor
d) Recurring factor
Explanation: This factor can be used for determining the ratio of map distance to ground distance which would be helpful for further calculations.
3. Which among the following scales is used to determine the original scale when the plan on the drawing sheet shrinks due to atmospheric conditions?
a) Vernier scale
b) Plane scale
c) Shrunk scale
d) Diagonal scale
Explanation: Shrunk scale is used to determine the original scale when any plan shrinks due to atmospheric conditions, which can be determined by a formula. By using the original scale further calculations can be done.
4. Which among the following methods is used for determining the precise position on the earth surface?
a) Geological surveying
b) Geodic surveying
c) Land surveying
d) Plane Surveying
Explanation: In Geodic surveying, spheroid surface of the earth is considered which might be possible for determining the precise position by avoiding any further assumptions.
5. Which among the following is one of the principles of surveying?
a) Taking measurements
b) Covering entire area
c) Determining the elevation differences
d) Working from whole to part
Explanation: By working from whole to part, it is possible to eliminate the errors and to localise the errors. Otherwise, it might expand in magnitude
6. Horizontal angle measured clockwise from geographic meridian to the direction of progress of a line is known as _______
a) Horizontal meridian
b) Vertical meridian
c) Azimuth
d) Horizontal bearing
Explanation: Azimuth is the angle measured from geographic meridian which is quite different from bearing as it is measured w.r.t north direction.
7. Which of the following is made in connection with the construction of streets, water supply systems, sewers?
a) Traverse surveying
b) Hydrographic surveying
c) Cadastral surveying
d) City surveying
Explanation: City surveying is made in connection with the construction of streets, water supply systems and sewers. A survey which deals with bodies of water for the purpose of navigation, water supply, harbor works or for the determination of mean sea level is hydrographic surveying.
8. Which of the following is a classification based on the instrument used?
a) Topographic surveying
b) Hydrographic surveying
c) Cadastral surveying
d) Traverse surveying
Explanation: Topographic surveying, Hydrographic surveying, Cadastral surveying classification is based on the nature of field survey. Traverse surveying, chain surveying is classified based on the type of instrument used.
9. Determining points of strategic importance are called _______
a) Topographic surveying
b) City surveying
c) Military surveying
d) Traverse surveying
Explanation: Determining points of strategic importance is military surveying. City surveying is made in connection with the construction of streets, water supply systems and sewers.
10. For exploring mineral wealth which type of surveying is used?
a) Topographic surveying
b) Engineering surveying
c) Military surveying
d) Mine surveying
Explanation: For exploring mineral wealth mine surveying is used. Determining points of strategic importance is military surveying.
