Constructor Details

BaseGDALGridCoverage2DReader

protected BaseGDALGridCoverage2DReader(Object input,
 Hints hints,
 String worldFileExtension,
 ImageReaderSpi formatSpecificSpi)
                                throws DataSourceException

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

Method Details

setCoverageProperties

protected void setCoverageProperties(ImageReader reader)
                              throws IOException

Setting Envelope, GridRange and CRS from the given ImageReader

Specified by:

setCoverageProperties in class BaseGridCoverage2DReader

Parameters:

reader - the ImageReader from which to retrieve metadata (if available) for setting properties

Throws:

IOException

getInfo

public ResourceInfo getInfo(String subname)

Description copied from class: BaseGridCoverage2DReader

Information about the named gridcoverage.

Specified by:

getInfo in interface GridCoverage2DReader

Overrides:

getInfo in class BaseGridCoverage2DReader

Parameters:

subname - Name indicing grid coverage to describe

Returns:

ResourceInfo describing grid coverage indicated
