What does intersection mean?

• A. Locating your position using a single landmark
• B. Finding the location of an unknown point by sighting 2 or more known points
• C. Reading terrain features
• D. Measuring distance with pacing

Answer: (B)

Intersection fixes your position by using lines of position from two or more known features. You identify at least two features you can see whose locations are known, then measure the bearing from your current location to each feature (or the back bearing from the feature toward you). On the map, plot a line from each known feature along the measured bearing toward your position. The point where these lines cross is where you are. Using more than two features can improve accuracy; with only one feature you’d get a single line of position but not a precise point.
