WWII Peleliu map?!?!?

Hello everyone I want to know if you can convert this map http://gamebanana.com/dods/maps/104844 by Dod: S to Garry’s mod … you could tell me how to do?!? and you could advise me some good site as well as mod garrysmod where I could find material for a machinima set during World War II in the Pacific … Thanks !!

Eh,assuming you already have DOD:S mounted for Gmod,you can just copy the map into your gmod maps folder.
