In hydrographic surveying, a tide gauge is used to:
सही उत्तर: घ) Record the water level at the time of soundings so that depths can be reduced to a datum
Since the water level changes with tides, soundings are reduced to a fixed datum using tide gauge readings.

When setting out a building foundation, horizontal boards fixed on pegs outside the trench lines, on which the wall or centre lines are marked, are called:
सही उत्तर: क) Profiles (batter boards)
Profiles/batter boards preserve the setting-out lines after excavation begins, with strings stretched between them.

LiDAR, increasingly used for terrain mapping, measures distances using:
सही उत्तर: क) Pulses of laser light
LiDAR (Light Detection and Ranging) times reflected laser pulses to generate dense 3D point clouds.

On a vertical aerial photograph, relief displacement of the image of a tall object occurs:
सही उत्तर: ग) Radially outward from the principal point (nadir) for points above the datum
Objects above the datum are displaced radially away from the nadir/principal point, the amount increasing with height and radial distance.

In aerial photography for mapping, the usual side (lateral) overlap between adjacent flight strips is about:
सही उत्तर: ग) 25% to 30%
Forward overlap is about 60% for stereo coverage, while side overlap between strips is usually about 25–30%.

The geoid is best described as:
सही उत्तर: घ) The equipotential surface of the earth's gravity that approximates mean sea level extended under the continents
The geoid is the gravity-defined level surface closest to mean sea level; orthometric heights are measured from it.

Differential GPS (DGPS) improves positional accuracy by:
सही उत्तर: घ) Applying corrections computed at a reference station of known position to the rover's observations
A base station at a known point calculates errors in GPS signals and transmits corrections to nearby receivers.

Galileo is the global navigation satellite system developed by:
सही उत्तर: ग) The European Union
Galileo is Europe's GNSS; GLONASS is Russian, BeiDou is Chinese and GPS is from the USA.

The 'zero circle' of a polar planimeter is the circle along which the tracing point moves:
सही उत्तर: घ) Without any rotation of the measuring wheel
Along the zero circle the wheel slides without rolling; its area is added when the anchor point is inside the figure.

In a mass haul diagram for earthwork, a rising curve (ordinates increasing along the chainage) indicates:
सही उत्तर: ग) Excavation (cutting)
Mass haul ordinates are cumulative volumes with cut positive, so a rising curve represents cutting and a falling curve filling.
