Plane Table Surveying

Plane table surveying is a method of surveying in which a drawing board or plane table is used to plot the features of the survey area. The following statements regarding plane table surveying are:

1. Accuracy: Plane table surveying is considered to be more accurate than chain surveying as it eliminates the errors due to chaining and measuring angles.

2. Centering: It is necessary to do accurate centering of the plane table to ensure accuracy in the survey. Even for small scale surveys, it is important to center the table properly.

3. Compass Rule: The compass rule is a method used to adjust the closing error in the traverse. This rule may be used in plane table surveying to adjust the traverse.

4. Resectors: Resectors are imaginary lines drawn from the instrument station to plot the position of objects in the field. These lines are used to determine the location of objects that are not directly visible from the instrument station.

Correct Answer: Option B (2, 3, and 4)

Explanation:

Option A is incorrect as statement 1 is incorrect. Plane table surveying is considered to be more accurate than chain surveying. Statement 2 is incorrect as it is necessary to do accurate centering of the plane table for all surveys, irrespective of the scale. Statement 3 is correct as the compass rule may be used in plane table surveying to adjust the traverse. Statement 4 is correct as resectors are used in plane table surveying to determine the position of objects in the field.

Option B is correct as all three statements are correct.

Option C is incorrect as statement 1 is incorrect.

Option D is incorrect as statement 2 is incorrect.
