Getting the precision of the equirectangular projection is key, as I'm trying to have as little distortion as possible when this gets applied to the manufacturer's template. Every small distortion can undo the carefully crafted design that makes the piece so eye catching. The point of the project is to prove that human designs are superior to computer generated RNG "designs", so distortion hurts that cause.
That's a good thing for cartographers everywhere, it increases our market value directly in an employer's eyes.
From a practical board game perspective I can touch it up easily enough and it will look great.
The original artwork was a slowly, exhaustively designed hand painted globe, so its from 3d to 2d; you probably know this, but I state this again just in case.
@Gidde Thanks!
