After a great idea from POS regarding map building resources Ive decided to sticky it in here and if anyone has links to topo maps or such like simply place them in here.
Thanks
A couple other resources for map builders.
Hexdraw- a program for creating hexes on your existing maps or making your own from scratch. This isn't for making CM maps, but for those campaign makers.
Milsketch- A program that has all the military symbols. they can be edited and dropped into the map of your choice.
