Compass Rose Defined

It has many names. It is also called Rose of the Winds or simply a wind rose. A compass rose is a figure that forms on a compass due to the intersecting lines pointing to different directions. Imagine an old magnetic compass. It has a suspended needle pointing north. You would see the directions laid out at the base. Typically, you would have north, south, east and west. You may also have north east, south east, south west and north west depicted as straight lines bisecting the gap between north and east, east and south, south and west, west and north. These lines form a pattern at the centre. This is known as a compass rose. In colored maps, a compass rose is often decked up with red, black and white.
