Sadly I don't have the ability to get the data to the group here. I
would essentially be equivalent to taking the GOES data and rotating
it by some 30-60 degrees cropping out the garbage areas and then
attempting to get the same answer...which I haven't done yet but will
try if I get a chance. Here's what would be a nice sequence and what
I would like to get to.

success = createGeoTiff(data, lats, lons, /MERCATOR)

One day...with IDL (or PythonXY) I will achieve this and the world
will be an easier place to project one's data. It's the kind of world
I'd like to live in.
