Well, the GeoCoord object is a little different. It relies on map
projection data being in a GeoTiff file. But, a geographic coordinate
system doesn't have a map projection associated with it. (Which is why
this wasn't initially included in either object.)

I've never seen a TIFF file with a geographic coordinate system, but I
imagine one exists. If you have one and can send it to me, I can take a
look at seeing if I can incorporate this into GeoCoord. It will be a day
or two before I can get to this.

Cheers,

David
