I'm thinking in terms of several different coordinate systems, each of which has its good and bad points, but I think I prefer named sectors tiling the sky as seen from Earth, along with a distance in light years. This is an Earth-centric polar coordinate system but without right-ascension/declination numbers. One could be relatively precise and say something like "Libra Sector 4A 378", where Libra Sector is a subsection of sky which probably includes most of the constellation Libra or is at least close to it, but it's the same size and shape the same as all the other named subsections of sky. 4A would localize it further, picking out one of several hundred subsectors, and 378 would be the distance from Earth in Light years. Or you could be less precise and give the name of the larger volume it's in, such as "Libra 350," Tagging a much larger general neighborhood which it may share with some other things (with distances in multiples of 50 ly). Of course sectors like that would be a lot wider the further away from Earth you get, for the same reason that longitude/latitude graticules on Earth are wider near the equator than at the poles. Out at the edges of Terragen space you'd probably have to use another subsector division to be precise. And the major problem with a polar coordinate system is that it isn't dead-simple to calculate distance the way it is with Cartesian coordinates; one can't just use the Generalized Pythagorean formula, but instead has to do trigonometric things that require thinking. Or, you know, a snip of code. I like the Earth-central polar coordinate/sector system, I think, because the distance from Earth is a pretty strong immediate indicator of how recently colonized and how 'civilized' it is and whether it's in the wormhole nexus and so on. Adopting a coordinate system where that's one of the most prominent features of a location makes it easier to immediately understand what *kind* of place we're talking about just from the coordinates, and it gives large volumes nice succinct tags which are primarily linguistic rather than numeric and as such easier to remember. Also, I just like the sound of sectors named after constellations. The succinct coordinates of some areas can become infamous in their own right; people will know what sector/distance is the Laughter Hegemony or the Verifex Volume, and, very importantly, can easily recognize coordinates that are "close to" those places. « Next Oldest | Next Newest »
