The resection by two point problem as compared to three point problem

In surveying, the resection by two-point problem as compared to the three-point problem gives more accurate results

Resection is a method used in surveying to determine the location of an unknown point by observing known points from that location. In the two-point resection method, observations are made from two known points to determine the position of the unknown point. This method is generally more accurate because it involves observations from two distinct directions, allowing for better triangulation and reducing errors.

On the other hand, the three-point resection method involves observations from three known points to determine the position of the unknown point. While it may seem more robust, it can sometimes be less accurate due to the potential for error propagation and the complexity of managing observations from three different directions.

Therefore, the correct option is Option A: gives more accurate results.
