meh, I was looking to put only one rose somehow on the map. But I can't think of a logical way.
Consider the problem of projecting the surface of the Earth onto a plane. The Mercator projection maps parallels to horizontals, lines of longitude to verticals. Thus you can place "just one rose" on the map.
However, other projections do not have this property that, for example, north is always vertical. On a polar stereographic map, you cannot place "just one compass rose". In fact, the FE map of the hubwards annulus looks similar to a polar stereographic map of the northern hemisphere.
Like if you split FE into four quarants, how could you name them?
Depends on how you split them. If you draw two orthogonal diameters, you could label them, in widdershins direction, "I", "II", "III", and "IV". Turns out this notation is already used by mathematicians to refer to the quadrants of any Euclidean plane.
