GeoTiffReader
final public class GeoTiffReader extends AbstractGridCoverage2DReader implements GridCoverageReader(Code)
this class is responsible for exposing the data and the Georeferencing metadata available to the Geotools library. This reader is heavily based on the capabilities provided by the ImageIO tools and JAI libraries.
