सही: ० / ०
-
The mean radius of the earth commonly used in surveying calculations is about:
सही उत्तर: क) 6371 km
The earth's mean radius is about 6371 km (its diameter about 12,742 km).

The flattening of the WGS 84 reference ellipsoid is approximately:
सही उत्तर: घ) 1/298
WGS 84 has flattening f = 1/298.257, reflecting the earth's slight polar compression.

NavIC (IRNSS) is the regional satellite navigation system developed by:
सही उत्तर: ग) India
NavIC (Navigation with Indian Constellation) provides positioning over India and the surrounding region, including Nepal.

A geostationary satellite orbits above the equator at an altitude of about:
सही उत्तर: ख) 35,786 km
At about 35,786 km the orbital period equals one sidereal day, so the satellite appears fixed over one point.

In aerial photography, 'drift' occurs when:
सही उत्तर: क) The aircraft's actual flight path deviates from the planned flight line, usually due to wind
Drift is the lateral shift of the flight path from the intended line; crab is the rotation of the camera relative to the track.

In mass haul calculations, 'overhaul' refers to:
सही उत्तर: घ) Hauling of earth beyond the free-haul distance, usually measured as volume × extra distance
Payment for overhaul is made for the volume moved beyond the free-haul limit, multiplied by the extra distance.

In 'three-wire' levelling, readings are taken on the upper, middle and lower cross hairs mainly to:
सही उत्तर: ग) Check the middle-hair reading (mean of the stadia readings) and obtain the sight distance
The mean of the stadia hair readings should agree with the middle reading, and the stadia intercept gives the sight length for balancing.

The 'missing line measurement' (MLM) program of a total station gives:
सही उत्तर: ख) The horizontal and slope distance and height difference between two remote target points, without occupying either
MLM computes the distance and elevation difference between two observed points from the instrument's measurements to each.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The 'remote elevation measurement' (REM) program of a total station is used to find:
सही उत्तर: क) The height of an inaccessible point, such as a cable or bridge soffit, above a prism placed directly below it
REM measures to a prism below the target, then uses vertical angles to the target to compute its height.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
With a total station, the 'stake out' (setting out) function is used to:
सही उत्तर: घ) Guide the placing of points on the ground at given design coordinates
The instrument computes and displays the distance and angle differences between the prism position and the design point until they match.
