No clue. I'm assuming that some of the maps were taken from during Beta and someone fleshed it out. It makes sense because those maps on gamergod are contributed by players. eq2.gamepressure.com has maps for the three realms as well, but nothing there yet. However, I would suggest getting the eq2map addon from the eq2interface site.

They all ready have good number of POI's listed and make it quite helpful.
