1. The types of errors that are of a cumulative nature and can be corrected are known as

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

3. The RL of the benchmark is 1000.0 m, and the back sight reading at the benchmark is 2.555 m. Find the staff reading of IS if the RL of IS is 1000.055 m

4. In the direct method of contouring, the process of locating points lying on a contour is known as

5. The location of the contour gradient for a highway is best set out from

6. Azimuth and altitude of a star

7. Contours are used to determine

8. The length of an Engineer's chain is

9. 'SPIRE TEST' is used in the permanent adjustment of theodolite for

10. Different grades are joined together by a

11. Find the contour interval for the map, 1: 25000 in IS & FPS

12. A disadvantage of plane table survey is:

13. For Y level, Cooke's, and Cushing levels, the line of collimation should coincide with

14. The tie line is run through the survey to

15. The shape of the vertical curve generally used is

16. Automatic level has advantages of

17. Leveling across a river is done by

18. A straight line tangential to the longitudinal curve of the level tube at its center is known as

19. A curve consists of two areas of different radii bending in the same direction and lying on the same side of their common tangent and their centers being on the same side of the curve is known as a

20. Sensitivity of a level tube is expressed by

21. The magnification of a telescope lens depends upon

22. If the magnetic bearing of a line is 65° and the true bearing 45°, then the magnetic declination is

23. The strength of the fix of a plane table is:

24. The multiplying constant of a tacheometer is

25. If the intercept on the vertical staff is observed as 1.5mm from a tacheometer, the horizontal distance between the tacheometer and staff station is

26. The curvature and refraction corrections applied to staff readings respectively are

27. The spacing of crosshairs in a stadia diaphragm of a tacheometer is 1.5mm, and the focal length of the objective glass is 30cm, the multiplying constant of the tacheometer is

28. *The line of collimation should be parallel to
