What does modified resection involve?

• A. Using a compass on an uneven terrain
• B. Locating position while on a linear feature
• C. Navigating without a map
• D. Determining coordinates in urban areas

Answer: (B)

Modified resection is a navigation technique that involves finding one's location by using a map and taking bearings from identifiable terrain features. When using modified resection, a person identifies two or more prominent features in their surroundings, takes bearings to these features, and then plots them on a map to determine their exact position. This approach focuses on locating oneself while using linear features such as roads or rivers, which can be easily identified on a map.

Thus, the answer that reflects this method correctly describes the process of locating position while on a linear feature, making it the best choice.
