Parameters:

input - Source object for which we want to build a BaseGDALGridCoverage2DReader.

hints - Hints to be used by this reader throughout his life.

worldFileExtension - the specific world file extension of the underlying format

formatSpecificSpi - an instance of a proper ImageReaderSpi.

Throws:

DataSourceException
