Ancient star map

Three-dimensional representation of the galaxy, including all planetary outposts once inhabited by the Ancients. Proclarush Taonas and Terra Atlantus are included on the map, which was discovered by SG-1 inside the abandoned Taonas outpost.

The VR room in the Ancient city of Atlantis in the Pegasus Galaxy also includes a star map of that region of space. Assuming it is like Taonas, the Atlantus outpost in Antarctica may also contain a star map.
