1. The chain length which is not the standard metric chain length is

2. *Error due to imperfect adjustment of plate level is termed as

3. Plane table survey is considered good as compared to other surveys since:

4. The minimum horizontal distance between any two consecutive contours is known as

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

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

7. The elevation (BM) of point A is 100 m. Backsight reading at A is 20, and foresight reading at B is 30 m. Find the RL of point B

8. The optical square is based on the principle of

9. If the observed reading of a level staff is 3.83m, and at the point sighted the staff is 0.15m off from the vertical through the bottom, the correct reading will be
