Question

In ____ method of plane table surveying, maximum number of ground measurements are made.
1. Radiation
2. Intersection
3. Resection
4. Traversing

Answer 1

Correct Answer - Option 1 : Radiation

Explanation:

Plane table surveying is the graphical method of surveying in which field observation and plotting are done simultaneously helping the surveyor to compare the plotted details with actual features of the ground. Method of plane table surveying are,

1) Radiation 

• It is the method of locating the point by drawing radial lines from the plane table station to that point.
• In the radiation method, the maximum number of ground measurements is made.

2) Intersection 

• It is a method of locating a point by the intersection of two rays from two different stations. 
• Only one linear measurement is made in the intersection method. 
• This method is also called Graphical triangulation.​

3) Resection 

• It is the method of locating the station occupied by the plane table when the position of that station had not been previously plotted from another station.

4) Traversing 

• It is that type of survey in which a number of connected survey lines form the framework.
