Grid north on a map is defined as?

• A. The true north
• B. The magnetic north
• C. The north indicated by the map's grid lines
• D. The direction of the north star

Answer: (C)

Grid north is the direction toward the north along the map’s grid lines. It’s the orientation you get when you follow the north–south lines of the map’s grid, not the geographic north or the direction a compass points. This reference is what you use when reading grid bearings or locating positions with grid coordinates. It can differ from true north (geographic north) and magnetic north (where a compass points), because the grid lines on a map may be aligned differently depending on the map’s projection. So the north shown by the map’s grid lines—the direction along the grid—is what grid north represents.
