-
The positions of bridge piers in a wide river, where direct taping is impossible, are commonly fixed by:
सही उत्तर: ख) Angular intersection from the ends of a measured base line on the bank
Theodolites at the ends of a shore base line set out computed angles; the piers lie where the lines of sight intersect.

A surface float travels 50 m along a straight reach of a river in 40 seconds. The surface velocity is:
सही उत्तर: क) 1.25 m/s
Velocity = distance ÷ time = 50 ÷ 40 = 1.25 m/s.

The 'upper culmination' (transit) of a star occurs when it:
सही उत्तर: घ) Crosses the observer's meridian at its maximum altitude
A star culminates twice daily on the meridian; at upper culmination it reaches its highest altitude.

The equinoxes are the two points (or instants) at which the sun:
सही उत्तर: ग) Crosses the celestial equator
At the equinoxes the sun's declination is zero, as it crosses the celestial equator, and day and night are nearly equal.

In the horizon system of celestial coordinates, the position of a star is given by its:
सही उत्तर: ख) Altitude and azimuth
The horizon system uses altitude above the horizon and azimuth measured along the horizon from north.

In the gnomonic projection, a property useful for navigation planning is that:
सही उत्तर: क) All great circles appear as straight lines
Because projection is from the earth's centre, every great-circle route plots as a straight line.

An 'equal-area' map projection is one that:
सही उत्तर: घ) Represents all areas in correct proportion to their true areas
Equal-area projections preserve area at the cost of shape; no projection can be both conformal and equal-area.

-
A 'choropleth map' shows statistical data by:
सही उत्तर: ग) Shading or colouring predefined areas (such as districts) according to the value of a variable
Choropleth maps, e.g. population density by district, use graded colours for administrative units.

In GIS, 'digitising' a paper map means:
सही उत्तर: ख) Converting map features into digital (usually vector) coordinates
Features are traced on screen or on a digitising tablet to create digital points, lines and polygons.

In GIS, 'network analysis' is typically used to:
सही उत्तर: क) Find the shortest or quickest route between locations along roads or pipes
Network analysis works on connected line features to solve routing, service area and allocation problems.
