‘The curvature of earth’s surface, is taken in te account only if the extent of survey is more
than :

(^) 100 sq. km. (B) 160 sq. ட (€) 300 sq. km. (D) 260 sq. पा.

The main principle of surveying is to work :
(^) from part to the whole (0) ‏سمط‎ whole to the part

(€) from higher level to lower level (10) from lower level to higher level

A well conditioned triangle has no angle less than :
(^) 20° (8) 30° (८) 455 (D) 605

The imaginary line passing through the intersection of cross hairs and the optical center of
the objective, is known as :

(A) Line of collimation (8) Line of sight
(C) Axis of the telescope (D) None of these

A relatively fixed point of known elevation above datum, is called :
(ಗಿ) Datum point (8) Reducedlevel (C) Reference point (D) Bench mark

The boundary of water of a still lake represents :
(ಡಿ) Level surface (ए) Horizontal surface

(0) Contour line (12) Concave surface

Closed contours of decreasing values towards their center, represents :
(ക) ahill (8) a depression (0) asaddle (D) ariver bed

To orient a plane table at a point with two inaccessible points, the method generally adopted,
is:

(2) Intersection (8) Resection
(C) Radiation (D) Two point problem
