If the smallest length that can be plotted accurately on paper is 0.25 mm, the smallest ground distance that can be shown on a map of scale 1:1000 is:
सही उत्तर: क) 0.25 m
0.25 mm × 1000 = 250 mm = 0.25 m on the ground; this decides the precision needed in field measurements.

A plan differs from a map in that a plan is:
सही उत्तर: घ) Drawn to a relatively large scale, covering a small area
Plans show small areas (e.g. buildings) at large scales; maps show larger areas at smaller scales.

A perambulator (measuring wheel) is used for:
सही उत्तर: ग) Rough measurement of distances, such as along roads, by counting wheel revolutions
The distance is obtained from the number of revolutions of a wheel of known circumference; it is suitable only for approximate work.

A pantograph is an instrument used to:
सही उत्तर: ख) Enlarge or reduce a map or plan to a different scale

In Nepal's cadastral (land) records, each individual land parcel is identified by its:
सही उत्तर: ग) Kitta number
Every parcel on a cadastral map sheet is given a kitta (plot) number, which is recorded in the land ownership certificate.

The velocity of flowing water in a river at a particular depth is measured using a:
सही उत्तर: ख) Current meter
A current meter's rotor turns at a rate proportional to water velocity.

A sextant is particularly useful in hydrographic surveying because it:
सही उत्तर: क) Can measure angles between two objects while held in the hand on a moving boat
Being hand-held and using mirrors to bring two objects into coincidence, the sextant can measure angles from an unstable platform.

-
In hydrographic surveying, a station pointer is used to:
सही उत्तर: घ) Plot the position of a sounding boat from two horizontal angles observed with a sextant to three shore points
The station pointer is a three-armed protractor that solves the three-point problem graphically on the chart.
