It is a method in which points with known coordinates are occupied to get the position of an unknown point.

• A. Resection
• B. Resection, known
• C. Traversal
• D. Intersection

Answer: (D)

Intersection is the method where you locate an unknown point by observing from two or more stations that have known coordinates and drawing sight-lines toward the unknown point. The unknown position is found where those sight-lines intersect. You measure directions or angles from each known point, and the intersection of the resulting lines gives the coordinates of the unknown point. More stations and careful measurements improve accuracy by allowing a best-fit intersection that minimizes errors. This differs from resection, where you stand at the unknown point and measure to known points to compute its coordinates.
