[Geotools-devel] Fun with wind arrows in polar projections

2023-11-30 Thread Andrea Aime
Hi, I'm working with wind maps, where typically the data contains (some way to compute) magnitude and directions of the wind vectors. Now, the "direction" is an angle that is used to rotate a symbol. The angle has an assumption... that north is up. However, take a non trivial projection, like
