are this maps canon ?
The 2258 map may be good looking, but is fanmade. It's somewhat right, but not quite (compare to the current "standard", the B5-RPG map from the basic rulebook, or the back of the "The Fiery Trial" supplement; also available at the Mongoose download area
). Don't be surprised if you use that one, and that find it doesn't match some other info... (or that it has a Vorlon symbol in the middle of the Narn Regime, an mistake AoG made in their beginning...)
The others, 2156, 2226, 2260 and 2263 were made by the HRT ("historical repair team" a bunch of freelancers that were working a lot with AoG on making sure history of their stuff matches). They were "works in progress", released after AoG's demise, and are rather good (if speculative on part of the 2263 map), except the 2156 one (while I was working with one of the HRT on some project, we realized it couldn't be right as a few of it's features made for serious historical entanglements and hard to believe fluff...)
