(On a linear one dimension scale, relative velocity is easy to understand, A moves at 10km/h and B at 11 km/h in the same direction, 1 hour later, B will be 1 km ahead of A, thus, their relative velocity is 1km/h)

As I wrote on another thread, the rotational movement around a point can only be properly shown with stereographic projections of the map. Hence, an equirectangular projection like the one you are showing, ascanius isn't appropriate to figure out the movement at the poles (something I suspect you found out already). Like groovey suggested, use G.projector to transform your map.
Yeah I'm reworking the map. Getting lines to 'line up' on the stereographic projection on G.projector is a pain. I started to draw, check, rework, rinse and repeat. I'm going to try using 360 degrees of a circle to line up everything instead, when in doubt use math

Thanks for the info bye the way
