1. The contour lines are perpendicular to the

2. A series of straight, parallel, and widely spaced contours on a map represent a

3. A series of closely spaced contour lines represent a

4. The contour lines merge or cross one another on the map in the case of

5. A series of closed contour lines on the map with higher to lower values inside them represent a

6. When the angular and linear measurements are equally precise in traversing, the balancing of the traverse is done by:

7. The main difference between theodolite and level is:

8. Staff intercept means

9. In a theodolite, staff readings for upper, middle, and lower crosshairs are 1.4, 0.9 & 0.4, respectively. If the height of the tower is 100m, then find the horizontal distance between the instrument station and the base of the tower

10. Theodolite traverse is plotted more accurately by

11. If the image formed by the objective of the telescope is not in the plane of crosshairs, it is called

12. The upper plate

13. The fundamental lines of transit of the theodolite are

14. In a theodolite, the line passing through the intersection of the horizontal and vertical crosshairs and the optical center of the object glass and its continuation is known as

15. The outer spindle attached to the lower plate in a transit theodolite is known as

16. The method of leveling in which the plane table is set at only one station to take detail is known as:

17. Which one of the following is not a personal error?

18. To orient a plane table without two inaccessible points, the method generally adopted is:

19. If the plane table is not horizontal in a direction at right angles to the alidade, the line of sight is parallel to the fiducial edge only for:

20. The resection by a two-point problem as compared to the three-point problem:
