The resected position of planetable station from three known position is unreliable if the station lies
Which of the following methods of plane tabling also known as “graphic triangulation”
The quick and most accurate method to solve three point problem in resection type of plane tabling is
The ‘fix’ of a plane table with three known points is good if the instrument station lies
Consider the following steps
1. Using Lehmann's rule, an improved position of station point is obtained
2. Procedure is repeated till the triangle of error is reduced to a point
3. Triangle of error is obtained
4. The plane table is levelled over the station point
5. Three resection tines are drawn from three well defined station points
The correct sequence of "Lehman’s Procedure" for solving the three point problem is
Consider the following statements regarding Plane Table surveying
1. It is less accurate than chain surveying
2. It is not necessary to do accurate centering of plane table for small scale surveys
3. Compass rule may be made use of for adjusting the plane table traverse
4. From the instrument station, resectors are drawn to plot the position of objects in the field
Which of these statements is/are correct?
