Which of the following statement(s) is/are false for plane table surveying ?
1. Two- point problem is a special case of resection method of plane table surveying.
2. Three – point problem is a special case of radiation method of plane table surveying.
Statement 1 is TRUE: Both the Two-point problem and the Three-point problem are
specialized methods of resection (which simultaneously achieves orientation). The primary
goal of a two point problem is to locate the position of the plane table on the drawing sheet by
sighting two well-defined, previously plotted points.
Statement 2 is FALSE: The Three-point problem is a special case of the resection method, NOT the radiation method. The radiation method is used to locate and plot the positions of objects on a drawing sheet from a single instrument station, whereas the three-point problem is specifically used to determine the unknown location of the instrument station itself by sighting three known points.
