Also, wikipedia describes this type of compass rose very well ...

https://en.wikipedia.org/wiki/Compass_rose


 A common compass rose as found on a nautical chart showing both true north (using a nautical star symbol) and magnetic north with magnetic variation. Also notice the correspondence between the 32-point rose (inner circle) and the modern 0–360° graduations.

I got a question from a fellow cataloger about a marking on the navigation map shown below, the “compass looking thingy.” Doers anyone have a more specific term for it?

                Howdy Brian,

 

                I have a map of fishing spots in the Florida Keys that has a big circle with compass directions on it … do you know what that is called?
