One Ropani, the land unit used in the hills of Nepal, is equal to:
सही उत्तर: क) 5476 square feet
1 Ropani = 74 ft × 74 ft = 5476 sq ft, which is about 508.74 m².

When adjusting levels run along routes of different lengths to the same point, the weight given to each route is usually taken as:
सही उत्तर: क) Inversely proportional to the route length
Variance in levelling grows with distance, so a shorter route is more reliable and gets more weight (w ∝ 1/L).

Two independent measured distances are added. Their standard errors are ±3 mm and ±4 mm. The standard error of the sum is:
सही उत्तर: घ) ±5 mm
Errors of independent quantities propagate as the root of the sum of squares: √(3² + 4²) = 5 mm.

On the celestial sphere, the point directly below the observer, opposite the zenith, is called the:
सही उत्तर: ग) Nadir
The nadir is diametrically opposite the zenith on the celestial sphere.

In astronomy, the 'declination' of a celestial body is its angular distance:
सही उत्तर: ख) North or south of the celestial equator
Declination is measured from the celestial equator along the hour circle, positive north and negative south.

The Lambert conformal conic projection is particularly suitable for mapping regions that:
सही उत्तर: क) Have a large east-west extent in the middle latitudes
A cone secant along two standard parallels keeps scale error small for mid-latitude regions elongated east-west.

The 'spectral resolution' of a remote sensing sensor refers to:
सही उत्तर: घ) The number and width of the wavelength bands it records
Finer spectral resolution means more and narrower bands, allowing better discrimination of materials.

-
The 'temporal resolution' of a satellite remote sensing system is:
सही उत्तर: ग) How often it can image the same area (revisit interval)
Temporal resolution is the revisit period, e.g. 16 days for a single Landsat satellite.

-
'Topology' in a vector GIS refers to:
सही उत्तर: ख) The spatial relationships among features, such as connectivity, adjacency and containment
Topology records how features relate, e.g. which lines connect at nodes and which polygons share boundaries.

In GIS, the Inverse Distance Weighting (IDW) method is used to:
सही उत्तर: क) Interpolate values at unsampled locations, giving nearer sample points more influence
IDW estimates a value as a weighted average of nearby samples, with weights decreasing with distance.
