In levelling, a larger staff reading on a point compared with another, from the same instrument set-up, means that the point is:
सही उत्तर: ग) Lower
The line of sight is horizontal at one height, so the further down it meets the staff (larger reading), the lower the ground point is.

Ranging rods used for marking survey stations are usually of length:
सही उत्तर: घ) 2 m or 3 m
Ranging rods are commonly 2 m or 3 m long, circular in section, with a pointed iron shoe at the lower end.

A 'swing offset' in chain surveying is taken by:
सही उत्तर: ख) Swinging the tape about the object point and finding the shortest distance to the chain line
The perpendicular from a point is the shortest distance, found by swinging the tape until the reading on the chain line is minimum.

-
A chain is tested before use by:
सही उत्तर: घ) Comparing it with a standard length (test gauge) marked on the ground
Chains are checked against a test gauge established with a standard steel tape and adjusted if too long or too short.

For laying sewers to a given gradient, sight rails are fixed at the ends of a section and the invert levels are checked with a:
सही उत्तर: क) Boning rod (traveller)
A boning rod of fixed length sighted between sight rails shows whether the trench bottom or pipe invert is at the required gradient.

In hydrographic surveying, a graduated pole used for measuring shallow depths is a:
सही उत्तर: क) Sounding rod
Sounding rods are used for shallow water; for greater depths a lead line or echo sounder is used.

-
In adjusting survey observations, the weight assigned to an observation is:
सही उत्तर: क) Inversely proportional to the square of its standard error (variance)
More precise observations get higher weight: weight ∝ 1/σ².

-
The probable error of a single observation is related to its standard deviation σ by:
सही उत्तर: ख) Probable error = 0.6745 σ
Half of the errors are expected to be smaller than the probable error, which equals 0.6745 times the standard deviation.

-
A Triangulated Irregular Network (TIN) represents a terrain surface by:
सही उत्तर: घ) Non-overlapping triangles joining irregularly spaced points of known elevation
In a TIN, sampled points are joined into triangles (often Delaunay), with denser triangles where the terrain is complex.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A Digital Elevation Model (DEM) is:
सही उत्तर: क) A digital representation of ground surface elevations
A DEM stores terrain heights, usually in a grid, for analysis such as slope, drainage and visibility.
