Class GeoTiffFormat

java.lang.Object
  org.geotools.data.coverage.grid.AbstractGridFormat
      org.geotools.gce.geotiff.GeoTiffFormat

All Implemented Interfaces:

org.opengis.coverage.grid.Format

public class GeoTiffFormat

extends AbstractGridFormat

implements org.opengis.coverage.grid.Format

Provides basic information about the GeoTIFF format IO. This is currently an extension of the Geotools AbstractGridFormat because the stream and file GCEs will pick it up if it extends AbstractGridFormat.

Constructor Detail

GeoTiffFormat

public GeoTiffFormat()

Creates a new instance of GeoTiffFormat

Method Detail

accepts

public boolean accepts(java.lang.Object o)

Currently, we only accept files, and we open the file to verify that it has a GeoKeyDirectory tag. If anything more subtle is wrong with the file, we deal with that when we try and read it.

Specified by:

accepts in class AbstractGridFormat

Parameters:

o - the source object to test for compatibility with this format. Must be a CatalogEntry.

Returns:

true if "o" is a CatalogEntry with a GeoTiff file as a resource.

getReader

public org.opengis.coverage.grid.GridCoverageReader getReader(java.lang.Object source)

If source is a file, this will return a reader object. This file does not use hints in the construction of the geotiff reader.

Specified by:

getReader in class AbstractGridFormat

Parameters:

source - must be a GeoTiff File

Returns:

a GeoTiffReader object initialized to the specified File.

getWriter

public org.opengis.coverage.grid.GridCoverageWriter getWriter(java.lang.Object source)

Always returns null.

Specified by:

getWriter in class AbstractGridFormat

Parameters:

source - ignored

Returns:

null, always.
