This month marks Star Trek’s 50th anniversary, so I thought it might be worth it to put together a little post about maps in Star Trek. This proved to be more fraught a subject than I expected. There are a lot of maps of the Star Trek universe out there by divers hands, some more official than others, and they don’t always agree on all points, as Sufficient Velocity forum member WhiteDragon25 griped in 2014:
Despite so many planets, stars, systems, and other locations that were mentioned and referenced to throughout the entire franchise’s run, we’ve never got an official and fully accurate map of the Trek universe. […] Hell, for all of the Star Wars EU’s faults, at least it managed to generate a universally accepted map! Star Trek on the other hand, despite being just as popular as Star Wars, cannot even figure out the sizes and positions of the Feds, the Romulans, and the Klingons in relation to one another!
WhiteDragon25 might be overstating things a bit: most of the maps have the Star Trek major powers in the same relative position (other empires like the Tholians are another matter). But the point remains. While original series canon assigned aliens to known nearby stars, and the shows occasionally used real locations (e.g. Wolf 359), episode writers did not start with a map and generally did not take spatial relationships into consideration, which no doubt has made the belated mapping process a bit more challenging.
In print form, the earliest map I’m aware of is Star Trek Maps (1980), which according to Memory Alpha was a pair of double-sided map posters accompanied by a fairly mathy booklet; of course, the Star Trek universe was a lot smaller then. Star Trek: Star Charts came out in 2002 and seems to be considered the most canonical of the maps in existence; it’s out of print now, though. Star Trek: Stellar Cartography (2013), a collection of ten 24″×36″ folded maps. (Note that I haven’t seen any of these maps.)
Online, Star Trek Dimension’s Cartography section has maps from the series as well as Christian Rühl’s Galactic Atlas. StarTrekMap.com, a fan site that appears to be based on Star Trek: Star Charts, uses an in-universe interface that functions well (scroll wheel zooming!) but is awfully small on large screens. Neither has been updated in years. The Star Trek Online game also has, as you might expect, a map.
