It is suppose to be for anyone who need the maps and zone information in EverQuest. I think every eq server with zones could use this atlas.
No, no they cant. If you haven't noticed already, alot of EQ server do not have the same set up, content, zone connections, etc... meaning you would need one personalized for each server. There are some servers very heavily customized that could (for example) make what used to be a city zone (Freeport) into a level 50+ Undead filled Paladin Heaven. Or Kaladim into a lvl 30 ghost riddled (thats twice i used that word today, im aware).
So i repeat, no you cant use these maps for every EQ server
