There is already a project to migrate the DH-Map for AoD vanilla Darkest-Hour-to-AoD-Map-Project Once it is finished, you easily can use DEC Map also.
Thanks. That wasn't what I was suggesting, but I do understand.
(I meant redrawing HoI2 vanilla map in DEC Map style. Not a popular idea, I know. It has been a while since Darkest-Hour-to-AoD-Map-Project was active (even links are dead) and I doubt time works to its advantage.)
