For example?  We use the point type for doing long/lat coordinates, and  for calculating distance between  places on
oneof our projects ... but I  take it you are thinking of something more elaborate then that?
 

Yes.  I was thinking of a 3D coordinate system and the various
transformations needed to span the globe, take into account
measurement errors, etc.

Cheers,
Brook
