-
The size of a vernier theodolite (e.g. a 20 cm theodolite) is designated by the:
सही उत्तर: ख) Diameter of the graduated circle of the lower plate
Theodolite size refers to the diameter of the main horizontal graduated circle.

On a contour map, a series of closed contours whose values decrease towards the centre represents a:
सही उत्तर: घ) Depression (pond or basin)
Closed contours with decreasing values inward indicate a depression; increasing values indicate a hill.

-
A low point or pass between two hills or summits is represented on a contour map as a:
सही उत्तर: क) Saddle
A saddle is a depression between two high points, shown by contours of two hills facing each other.

Points A and B, 40 m apart, have RLs of 101.0 m and 106.0 m. Assuming a uniform slope, the 105 m contour lies at what distance from A?
सही उत्तर: क) 32 m
Rise from A to the contour = 4 m out of a total of 5 m, so distance = 40 × 4/5 = 32 m from A.

For a small-scale map of rugged, hilly terrain, the contour interval is generally kept:
सही उत्तर: ख) Larger
Contour interval increases with smaller map scale and steeper ground; otherwise contours would be too crowded to read.

Remote sensing in surveying and mapping refers to:
सही उत्तर: ख) Obtaining information about the earth's surface without physical contact, e.g. from satellite or aerial sensors
Remote sensing acquires data by sensors on aircraft or satellites that record reflected or emitted energy, without touching the objects.

-
On a contour map, contours that are closely spaced at higher elevations and widely spaced at lower elevations represent a:
सही उत्तर: ख) Concave slope
A concave slope is steep near the top and gentle near the bottom, so contours crowd together at the higher levels.

-
A line laid out on the ground surface maintaining a constant inclination to the horizontal, as for a hill road or canal, is called a:
सही उत्तर: क) Contour gradient
A contour gradient (grade contour) is a line on the ground with a uniform specified slope, set out using a level, Abney level or tangent clinometer.

-
The permanent adjustment of a dumpy level that is carried out first is to make:
सही उत्तर: ख) The axis of the bubble tube perpendicular to the vertical axis
First the bubble axis is made perpendicular to the vertical axis; then the line of collimation is made parallel to the bubble axis.

A back sight of 1.500 m is taken on a benchmark of RL 200.000 m. The height of instrument is:
सही उत्तर: ख) 201.500 m
HI = RL of benchmark + back sight = 200.000 + 1.500 = 201.500 m.
