Grid north is defined as the north established using which feature on a map?

• A. The vertical grid lines
• B. The compass needle
• C. The true north meridian
• D. The geographic north pole

Answer: (A)

Grid north is the direction defined by the map’s grid itself—the north along the vertical grid lines. These lines run north–south and establish the north direction for grid bearings on the map. This differs from true north, which points toward the geographic North Pole, and from magnetic north, which is where a compass needle points. The grid’s orientation is fixed by the map’s projection, so grid north follows those vertical grid lines rather than the pole or the compass.
