That early map that SE released is terribad and should not be treated as useful for consultation.The dimensions are off and most of it is squished together in a way that makes even the BO2 map look good. Please ignore it.
It is possible that SE will release a more comprehensive updated map in the future, but their attention for the moment still seems to be mostly focused on getting out new game content and attempting to fix bugs. There are some fan-made things, but they universally have issues due to the inherently problematic nature of reconciling the various maps shown in the games. Shrykull's SR1 map is oft-cited, but again, it has some issues. He also recently put out an SR2 version, which is included in that same thread.http://nosgoth.yuku.com/topic/6650/Re-S ... st?page=-1
The best solution would be for SE to release a new official one. No matter what, some compromises are going to have to be made, but at least that way they'll be canon.
