Hi,

Could someone steer me in the right direction here? I have a terrain
data set that looks like:

   (lon, lat) --> alt

I have a lovely 2D image by mapping lon -> XAxis, lat -> YAxis, and alt
-> RGB. How would I go about displaying this with a Lambert conformal
projection?

Should I use visad.data.hdfeos.LambertConformalConic for the
CoordinateSystem? 

I'll have multiple Data objects that are functions of (lon, lat) and I'd
rather not have to define them with a special CoordinateSystem. (I've
been looking at Test11 which does this for PolarCoordinateSystem.)  I'd
like to be able to change projections by changing a property of my
Display, not my Data. 

I'd appreciate any suggestions.

Thanks,
Doug
