List of top Agricultural Engineering and Technology Questions on Surveying asked in ICAR AIEEA (PG)

The contour interval depends on: (A) time and expanse of field and office work, (B) purpose and extent of survey, (C) scale of plan and nature of country, (D) contour characteristics, (E) interpolation of contours. Choose the correct answer from the options given below:
The instruments required for contour survey are: (A) dumpy level, (B) levelling staff, (C) chains and tapes, (D) odometer, (E) prismatic compass. Choose the correct answer from the options given below:
Given below are two statements:
Statement (I): The axis of the bubble tube should be perpendicular to the vertical axis in dumpy level.
Statement (II): The line of collimation of the telescope of the dumpy level should be perpendicular to the axis of the bubble tube.
In light of the above statements, choose the most appropriate answer from the options given below.
(A) In levelling, datum surface is an arbitrary surface with reference to which the elevations of the points are measured and compared.
(B) The line of collimation or the line of sight is the line joining the intersection of the cross-hairs to the optical centre of the object glass and its continuation.
(C) A foresight is the first staff reading taken after setting up the instrument in any position.
(D) The height of instrument is the elevation of the plane of collimation when the instrument is levelled.
(E) A change point indicates the shifting of the instrument, both back sight and intermediate sight are taken on this change point.

Choose the correct answer from the options given below:

Choose the correct answer from the options given below:
Which points should be kept in mind while selecting the stations?
(A) The survey lines should be as few as possible.
(B) If possible, a base line should be run roughly through the middle of the area on which the framework of triangles covering the major portions of area may be built up.
(C) Offsets should be long particularly for locating the important features.
(D) All the triangles should be well conditioned.
(E) The main principle of surveying is to work from the part to the whole.
