Hmm... I would have thought that the Google projection, like most mercator
projections, would have had warped features a little differently. For example,
Greenland would look radically different on a Mercator projection than a WGS84
"projection". Maybe I should try a different "world" projection to test whether
the reprojection is working? I tried a Robinson and Mollweide projection but
they seem to be unsupported (I can create an envelope but the coverage
transformation is bombing out). Anyone know of another global projection I can
test with? Just need an EPSG code to see if the coverage transformation is
working.
Thanks in Advance!
Peter

You're not missing anything I think, in that kind of reprojection only the
georeferencing
changes as far as I remember, the number of pixels is preserved. But you're not
writing out
the georeferencing so you don't see it.
