| This class provides an abstraction from the details of TIFF data access for
the purpose of retrieving GeoTIFFWritingUtilities metadata from an image.
All of the GeoKey values are included here as constants, and the portions of
the GeoTIFFWritingUtilities specification pertaining to each have been copied
for easy access.
The majority of the possible GeoKey values and their meanings are NOT
reproduced here. Only the most important GeoKey code values have been copied,
for others see the specification.
Convenience methods have been included to retrieve the various TIFFFields
that are not part of the GeoKey directory, such as the Model Transformation
and Model TiePoints. Retrieving a GeoKey from the GeoKey directory is a bit
more specialized and requires knowledge of the correct key code.
Making use of the geographic metadata still requires some basic understanding
of the GeoKey values that is not provided here.
