Two-point problem in plane table surveying is solved by:
Choose the correct answer
Resection using 3 known points
Finding instrument station using 2 known plotted points — trial and error or mechanical solution (Bessel's method)
Radiation from 2 stations
Intersection from 2 stations
Correct Answer
B. Finding instrument station using 2 known plotted points — trial and error or mechanical solution (Bessel's method)
Why is this the answer?
Two-point problem: locate table at unknown point using 2 known plotted points. Method: sight both known points, plot rays, move board until both rays pass through respective points on board. Three-point problem: uses Lehmann's or Bessel's method.
