IMHO the cited wiki article should be fixed. It does not make sense to speak about altitudes for almost any of the objects that we map, (it's a term that fits well for an airplane or maybe the ISS), and connections should be created following a topological model. It wouldn't make sense to speak about "elevation" either, because many of the things that we map have a height, so there is a range of elevations. And many lines that we map are logical or legal, rather than physical.<br></div><div><br></div><div>Cheers</div><div>Martin<br></div></div></div>
