Norm,

GDAL mostly works at a higher level, and doesn't give the same detailed
level of access to the geotiff tags.

The libgeotiff "listgeo" utility in combination with geotifcp does something
similar, but is not graphical - which I think is part of the appeal of
GeoTIFFExaminer.

I would *claim* that the commandline tools do everything people need, and
that GeoTIFFExaminer is just a convenience (though I could be missing
something), and so I'm not too awfully excited about reproducing it's
functionality.

Note, it is not critical for Autodesk to open source GeoTIFFExaminer.
But it would be nice if it could become available to redistribute for
free as it used to be.

Best regards,
