All you get is the contours...... IF the map has any..... You have to add the trees etc......of course it works with SPWW2.... both games used the exact same map code but that link you posted shows plenty of contours
it's up to you to add in everything else. In map making for historical maps getting the contours, right was a BIG part of the work......this eliminates that part of the work but it doesn't hand you a finished map
