GeoTiffMetadata2CRSAdapter
final public class GeoTiffMetadata2CRSAdapter (Code)
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.

Constructor Detail
GeoTiffMetadata2CRSAdapter
public GeoTiffMetadata2CRSAdapter(Hints hints)(Code)
Creates a new instance of GeoTiffMetadata2CRSAdapter
Parameters:
  hints - a map of hints to locate the authority and object factories.(can be null)




Method Detail
createCoordinateSystem
public CoordinateReferenceSystem createCoordinateSystem(GeoTiffIIOMetadataDecoder metadata) throws IOException, FactoryException(Code)
This method creates a CoordinateReferenceSystem object from the metadata which has been set earlier. If it cannot create the CoordinateReferenceSystem, then one of three exceptions is thrown to indicate the error. the CoordinateReferenceSystem object representingthe file data
throws:
  IOException - if there is unexpected data in the GeoKey tags.
throws:
  FactoryException -
throws:
  NullPointerException - if the csAuthorityFactory,datumFactory, crsFactory ormetadata are uninitialized
throws:
  UnsupportedOperationException - if the coordinate system specified by the GeoTiff file is notsupported.



get
public static Object get(Object key)(Code)
Returns an object from the pool for the specified code. If the object was retained as a , the Reference.get referent is returned.
Parameters:
  key - to use for doing the lookup inside the pool. a cached instance of a GeoTiffMetadata2CRSAdaptersuitable for the provided key.



getHints
public Hints getHints()(Code)
Returns the Hints for this GeoTiffMetadata2CRSAdapter . Hints for this GeoTiffMetadata2CRSAdapter.



getRasterToModel
public MathTransform getRasterToModel(GeoTiffIIOMetadataDecoder metadata) throws GeoTiffException(Code)
Create the grid to world (or raster to model) transformation for this source repsecting ALWAYS the OGC PixelInCell.CELL_CENTER onvention for the ImageDatum of the underlying ImageCRS .
