What is intersection in terms of navigation?

Intersection in navigation refers to the technique used to determine the location of an unknown point by observing and sighting two or more known reference points. This method relies on drawing lines from the known positions to the unknown position; where these lines converge, the location of the unknown point is established.

This is a critical skill in navigation, particularly in situations where GPS is unavailable or in environments where landmarks are the primary navigation tools. By utilizing the intersection method, navigators can accurately pinpoint their location based on relative positioning with known landmarks, which is fundamental in various military and outdoor scenarios.
