Q.1

Hydro-graphic surveys deal with the mapping of
Large water
Heavenly bodies
Mountainous region
Canal system
Pick up the correct statement from the following
The diaphragm plays no part in defining the line of sight
The optical centre of the objective plays no part in defining the line of sight
The eyepiece plays no part in defining the line of sight
None of these.
In chain surveying tie lines are primarily provided
To check the accuracy of the survey
To increase the number of chain lines.
To take offsets for detail survey
To avoid long offsets from chain lines
The intercept of a staff
Is maximum if the staff is held truly normal to the line of sight.
Is minimum if the staff is held truly normal to the line of sight.
Increases if the staff is tilted towards normal.
Decreases if the staff is tilted away from normal.
Closed contours of decreasing values towards their centre, represent
A hill.
A river bed.
A saddle or pass.
A depression.
The accuracy of measurement in chain surveying, does not depend upon
Scale of the plotting
Importance of the features
Length of the offset
General layout of the chain lines.
07

The real image of an object formed by the objective, must lie
At the centre of the telescope
In the plane of cross hairs
At the optical centre of the eye-piece
Anywhere inside the telescope.
