Toby, hello. On 2008 Dec 8, at 23:00, Toby A Inkster wrote: > :Point a rdfs:Class ; > rdfs:comment "A point in three dimentions"@en . I've done some preliminary work on this sort of thing in the context of astronomical images, and the FITS model. It's the sort of thing that gets fiddly rather quickly. What's your application? > Effectively something like <http://www.w3.org/2003/01/geo/> but > operating on arbitrary 3D reference planes instead of just WGS84. WGS84 would, I imagine, cover altitude as well.... and indeed it appears (having just looked), that http://www.w3.org/2003/01/geo/ does include a geo:alt predicate. How general do you want your coordinate system to be (there's a whole world of positively delicious complication waiting to be explored there!)
