What does the term "intersection" refer to in land navigation?

The term "intersection" in land navigation specifically refers to the process of determining the position of an unknown point by using two or more known points. When navigators use this method, they take bearings from the known locations and use them to locate the target point through the intersection of the lines of sight. This technique is particularly useful in outdoor settings where GPS may not be reliable, allowing for accurate triangulation based on visible landmarks or navigational aids.

Understanding intersection is essential for effective navigation, especially in situations where precise coordinates are needed but cannot be directly observed or measured. This method enhances situational awareness and helps maintain orientation in unfamiliar terrain.
