20000321: Georeferencing classes

Hi-

Has anyone out there developed any VisAD Data objects for 
georeferencing? Right now there's visad.MapProjection for defining
map projections and I'm working on a class (LatLonTuple) as a 
data object representing lat/lon points.  Before I go too 
far down the path, I wanted to see if someone else has already 
been there.  I was thinking that perhaps those working on the
GeoVista project or Ugo might have something.

Thanks.

Don
