-
The degree of a curve (arc definition) is the angle subtended at the centre by an arc of standard length. As the radius increases, the degree of curve:
सही उत्तर: ख) Decreases
Degree of curve is inversely proportional to radius; flatter curves (larger R) have smaller degree.

Transiting (plunging) a theodolite means:
सही उत्तर: ग) Rotating the telescope about its horizontal axis through 180° in the vertical plane
Transiting reverses the telescope end-for-end by turning it about the trunnion (horizontal) axis.

The method of measuring several angles at a station successively by closing the horizon is called:
सही उत्तर: ग) Reiteration (direction) method
In the reiteration method, angles are measured in succession around the station and the horizon is closed for a check.

An echo sounder measures water depth by:
सही उत्तर: ग) Timing the return of a sound pulse from the bed
Depth = (velocity of sound in water × time for the echo) / 2.

Depth measurements of water bodies in hydrographic surveying are called:
सही उत्तर: ख) Soundings
Soundings are measurements of water depth, made with a sounding rod, lead line or echo sounder.

A theodolite measures:
सही उत्तर: ख) Horizontal and vertical angles
A theodolite measures both horizontal and vertical angles and can also be used for ranging, levelling and tacheometry.

The method of contouring in which RLs are taken at grid points and contours are interpolated is called the:
सही उत्तर: घ) Indirect method (grid/squares)
In the indirect method, spot levels at grid corners are taken and contours are drawn by interpolation.

For stereoscopic coverage in aerial photography, the usual forward (longitudinal) overlap between successive photographs is about:
सही उत्तर: ख) 60%
Forward overlap of about 60% (side overlap about 25–30%) is used so each ground point appears in at least two photos for stereo viewing.

A vertical photograph is taken with a 150 mm focal length camera from 3000 m above flat ground. The photo scale is:
सही उत्तर: क) 1 : 20,000
Scale = f/H = 0.15/3000 = 1/20,000.

-
The scale of a vertical aerial photograph taken with camera focal length f from a flying height H above flat ground is:
सही उत्तर: क) f/H
Photo scale = focal length / flying height above ground, e.g. 150 mm / 1500 m = 1/10,000.
