org.geotools.coverage.grid.imageio.geotiff.metadata.GeoTiffMetadata2CRSAdapter
The GeoTiffMetadata2CRSAdapter is responsible for interpreting the metadata provided by the GeoTiffIIOMetadataDecoder for the purposes of constructing a CoordinateSystem object representative of the information found in the tags.
This class implements the flow indicated by the following diagram:

To use this class, the GeoTiffReader should create an instance with the CoordinateSystemAuthorityFactory specified by the GeoTiffFormat instance which created the reader. The image specific metadata should then be set with the appropriate accessor methods. Finally, the createCoordinateSystem() method is called to produce the CoordinateReferenceSystem object specified by the metadata.
