I'm as much a fan of Okudagrams and works like Geoffrey Mandel's Star Trek Star Charts as anyone. Having said that, how useful would the sorts of displays that we've seen in Trek shows, films and books be to people of the Star Trek universe? At best, these displays are two-dimensional projections. Ignoring that most of Trek's space scenes are very two-dimensional in nature, space is very three-dimensional. Given that, how useful is a single, two-dimensional diagram? The various Trek maps that have been published over the years have the same problem. What good is a "plan view" of the galaxy without information about the third dimension?
