North Arrow (cartography)

A north arrow in cartography is a symbol on a map that shows which direction is north. It helps users orient the map correctly with the real world and understand the layout of the features depicted. The arrow is typically an arrow shape pointing upward or in a specific direction, often labeled "N" for north. Including a north arrow ensures clarity in navigation and spatial understanding, especially when the map is rotated or used in the field. It’s a fundamental tool for accurately interpreting geographic information and establishing the map's orientation relative to the Earth's surface.
