What is the primary function of a compass rose?

The primary function of a compass rose is to determine locations and directions. A compass rose provides directional indicators, typically showing the cardinal directions (north, south, east, and west) and often includes intermediate directions (northeast, northwest, southeast, southwest). This tool is essential for navigation as it helps users understand how to orient themselves on a map and find their way in relation to the layout of the surrounding area.

In contrast, measuring distances between two points, marking political boundaries, and identifying geographic features are specific tasks that may require different tools or representations on a map, but they do not encompass the fundamental role of a compass rose in navigation and directionality.
