Which method is used to orient a map without a compass?

• A. Terrain association
• B. Resection
• C. Triangulation
• D. Dead reckoning

Answer: (A)

Orienting a map without a compass relies on matching what you see on the ground to the features shown on the map. This is terrain association: you look for distinctive, recognizable features—such as a river meander, a road junction, a hill, or a building cluster—and rotate the map until those features line up with their real-world locations. When multiple features align, you’ve established the map’s orientation relative to north, so you know which way you’re facing on the map. Other methods focus on pinpointing your position or calculating movement rather than just aligning the map. Resection uses bearings to known landmarks from your current position to determine where you are, triangulation uses geometry with known points to locate you, and dead reckoning estimates position by tracking speed and direction over time. They’re about figuring out location or path, not simply orienting the map, which is why terrain association is the best fit for orienting without a compass.
