Which of the following is NOT a correct statement?
Show Hint
In surveying, the first reading is called a 'Back Sight', and the last reading is called a 'Fore Sight'.
Updated On: Jan 2, 2026
- The first reading from a level station is a 'Fore Sight'.
- Basic principle of surveying is to work from whole to parts.
- Contours of different elevations may intersect each other in the case of an overhanging cliff.
- Planimeter is used for measuring 'area'.

The Correct Option is A
Solution and Explanation
In surveying, the first reading taken from a level station is called a 'Back Sight', not a 'Fore Sight'. A 'Fore Sight' is the last reading taken at the end of a leveling operation to establish the elevation at the new point.
- Option (A) is incorrect, because the first reading from a level station is a 'Back Sight', not a 'Fore Sight'.
- Option (B) is correct, as the basic principle of surveying is to start from a known reference point (whole) and work towards the unknown parts.
- Option (C) is correct because in the case of an overhanging cliff, contours may intersect due to changes in elevation.
- Option (D) is correct, as a planimeter is a tool used to measure the area of an irregular shape.
Thus, the correct answer is option (A).
Final Answer: (A) The first reading from a level station is a 'Fore Sight'.
- Option (B) is correct, as the basic principle of surveying is to start from a known reference point (whole) and work towards the unknown parts.
- Option (C) is correct because in the case of an overhanging cliff, contours may intersect due to changes in elevation.
- Option (D) is correct, as a planimeter is a tool used to measure the area of an irregular shape.
Thus, the correct answer is option (A).
Final Answer: (A) The first reading from a level station is a 'Fore Sight'.

Top Questions on Principles of surveying
- To finalize the direction of a survey, four surveyors set up a theodolite at a station P and performed all the temporary adjustments. From the station P, each of the surveyors observed the bearing to a tower located at station Q with the same instrument without shifting it. The bearings observed by the surveyors are 30° 30' 00", 30° 29′ 40′′, 30° 30′ 20′′ and 30° 31′ 20′′. Assuming that each measurement is taken with equal precision, the most probable value of the bearing is
