Forum:Location/Map Key

I have noticed several locations are given the designations from what appears to be both the "Secrets of" series of books as well as this map. Unfortunately, not everything matches up and I am curious if the map (which I believe is from the 3rd Edition product line) has a known key. If not, is there a master "Locations from Rokugan" list? I'm compiling lists from the various books but I don't want to post them on the Wiki if the numbering system has been trumped by a product I am currently unaware of.
