have spilt the beans, here's their description:
The Starfleet Reference Library: Stellar Cartography collects together ten original, never-before-seen large-format maps of the Star Trek universe. Pulled from the cartography archives of Starfleet Academy, these beautifully reproduced maps provide a rare opportunity to view the expanse of Federation space (and beyond) through the multiple lenses of the Galaxy's key players.
The maps include an ancient Vulcan map, a Klingon Empire map from the pre-Organian Peace Treaty era (in the native Klingon), an official Romulan government map of the Empire, a native Cardassian Union map from the Bajor occupation, along with Federation maps from the modern era. Housed in a handsome clamshell case and paired with a fully-illustrated reference book providing detailed information on planets, systems, and topography, this exclusive collection showcases the Star Trek universe like never before.
Sounds like fun to me, having maps from different times and cultural perspectives should make it a very different experience from Star Charts;
which did that a little bit I suppose, but not as full on as this sounds.
