Grid North is the north indicated on a map.

• A. East
• B. Magnetic North
• C. True North
• D. Grid North

Answer: (D)

Understanding different ways north is defined on maps helps you read coordinates correctly. Grid North is the north indicated by the map’s grid lines—the direction toward the top of the map along those grid lines. It’s the reference used when you’re following or plotting grid references within that map’s coordinate system. This is different from True North, which points toward the geographic North Pole, and from Magnetic North, the direction a compass points (which varies by location and time). East is simply a horizontal direction and is not north. So the north shown by the map’s grid is Grid North.
