a) Topographic Surveying
b) Hydrographic Surveying
c) Geodetic Surveying
d) Plane Surveying
View Answer
Explanation: Type of surveying in which the mean surface of the earth is considered as a plane and the spheroidal shape is neglected is plane surveying.
4. Type of surveying in which the shape of the earth taken into account is __________
a) Topographic Surveying
b) Hydrographic Surveying
c) Geodetic Surveying
d) Plane Surveying
View Answer
Explanation: Type of surveying in which the shape of the earth taken into account is geodetic surveying. The survey which deals with bodies of water for purpose of navigation, water supply, harbor works or for the determination of mean sea level is hydrographic surveying.
5. Horizontal projection of an area and shows only horizontal distances of the points is __________
a) Contour lines
b) Levelling
c) Surveying
d) Plan
View Answer
Explanation: Horizontal projection of an area and shows only horizontal distances of the points is plan or map. Finding the elevations of a point with respect to a given or assumed and establish points given elevation or at different elevations with respect to given or assumed dactum is levelling.
6. What type of surveys needs to fix the boundaries of municipalities and of state and federal jurisdictions?
a) Topographic Surveying
b) Hydrographic Surveying
c) Cadastral Surveying
d) City Surveying
View Answer
Explanation: The surveys need to fix the boundaries of municipalities and of state and federal jurisdictions are cadastral surveying. Survey which deals with bodies of water for purpose of navigation, water supply, harbor works or for the determination of mean sea level is hydrographic surveying.
7. Determining the absolute location of any point or the absolute location and direction of any line on the surface of the earth is called _______
a) Topographic Surveying
b) Astronomical Surveying
c) Cadastral Surveying
d) Hydrographic Surveying
View Answer
Explanation: Determining the absolute location of any point or the absolute location and direction of any line on the surface of the earth is astronomical surveying.
8. Determining different strata in the earth’s crust is called as_______
a) Mine Survey
b) Geological Survey
c) Geodetic Survey
d) Archaeological Survey
View Answer
Explanation: Determining different strata in the earth’s crust is the Geological Survey. Type of surveying in which the shape of the earth taken into account is geodetic surveying.
9. Determining unearthing relics of antiquity is called as_______
a) Mine Survey
b) Geological Survey
c) Geodetic Survey
d) Archaeological Survey
View Answer
Explanation: Determining the unearthing relics of antiquity is an archaeological survey. Determining different strata in the earth’s crust is the geological survey.
10. In which surveying, shape of earth is taken into consideration?
a) Plane surveying
b) Geodic surveying
c) Topographic surveying
d) Geological surveying
View Answer
Explanation: In Geodic surveying, shape of the earth is considered for carrying out high precise work. In case of Plane surveying, spheroid shape is neglected and entire area is considered in the form of triangles. Topographic surveying consists of vertical and horizontal locations of points whereas Geological surveying determines earth’s strata.
11. Representing large scale on the surface of the earth is____________
a) Plan
b) Map
c) Scale
d) Area
View Answer
Explanation: For any representation, if it consists large scale then it represents plan and for small scale it represents map.
12. Which of the following units measurement system is generally employed?
a) Centesimal system
b) Hours system
c) Minutes system
d) Sexagesimal system
View Answer
Explanation: Since most surveying instruments are graduated according to this system, Sexagesimal system is widely used in India. Centesimal system is having a great approach in Europe for its adaptability in interpolation. Hours system is having its use in navigation.
13. The ratio of map distance to corresponding ground distance is called as__________
a) Representative factor
b) Representation factor
c) Reciprocating factor
d) Recurring factor
View Answer
Explanation: This factor can be used for determining the ratio of map distance to ground distance which would be helpful for further calculations.
14. 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
View Answer
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.
15. 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
View Answer
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.
16. 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
View Answer
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.
17. Design a vernier for a theodolite circle divided into degrees and one fourth degrees to read to 20ꞌꞌ.
a) 55
b) 45
c) 65
d) 35
View Answer
Explanation: W.K.T, L.C = s/n
S = (1/4)˚= 15ꞌ and L.C=20ꞌꞌ=20/60 min.
So, 20/60 = 15/n
n = 45.
18. 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
View Answer
Explanation: Azimuth is the angle measured from geographic meridian which is quite different from bearing as it is measured w.r.t north direction.
19. The formula for shrunk scale can be given as___________
a) Original scale*shrinking factor
b) Shrunk scale*shrinking factor
c) Vernier scale* shrinking factor
d) Diagonal scale* shrinking factor
View Answer
Explanation: The shrinkage factor obtained by the ratio of shrunk length to actual length multiplied by the original scale will give the shrunk scale formula.
