Could you also ask Panonian? You have higher status here, and so if you ask him he would probably be more willing than if I do - your voice carries more weight. As for the source, the image that is up for deletion is in my opinion a good enough source. Panonian has used less than that, and with that he has made these maps that I linked you. I suspect that he uses coreldraw's suite program called corel-trace. I don't know though. (  ).
