ON COORDINATES: a) what you describe is more specific than a geolocation (which may be expressed by other means than coordinates). I suggest to give the data type the more specific name: geocoordinates b) with respect to precision: I don't understand the reasoning to stick this to degrees.

Thanks to the pointer, Katie. I meant to look into Max' work for a while, but failed. Now I did and asked him many questions :) So the biggest difference is that Max uses dim to represent what we mean here with precision. And dim is somehow related to precision in a globe dependent way (which is

Hey, Why use Q2 (earth) as the glob, and not Q215848 (WSG84)? That would be a lot clearer, I think. Since WGS84 implies Earth, this works for Earth. Is such an implication always present though? What if I want to describe a location on some random planet - I suspect you'd have to specify some

Hey, For every globe we would always need a geodesic system. My concern is not having the geodesic system field. This is fine. My concern is not having a globe field. Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic. Don't be evil. -- ___

geocoordinates Yep, agreed. Or just coordinates. yes, probably better without a geo if it shall work for moon or mars as well. However, http://en.wikipedia.org/wiki/Coordinate_system is far broader term. But I cannot find a correct superclass term for Geographic/Selenographic/Martiographic(?)
