This operation provides the following functionality: <p> <UL> <LI><strong>Resampling</strong><br> The grid coverage can be resampled at a different cell resolution. Some implementations may be able to do resampling efficiently at any resolution. Also a non-rectilinear grid coverage can be accessed as rectilinear grid coverage with this operation.</LI> <LI><strong>Reprojecting</strong><br> The new grid geometry can have a different coordinate reference system than the underlying grid geometry. For example, a grid coverage can be reprojected from a geodetic coordinate reference system to Universal Transverse Mercator CRS.</LI> <LI><strong>Subsetting</strong><br> A subset of a grid can be viewed as a separate coverage by using this operation with a grid geometry which as the same geoferencing and a region. Grid range in the grid geometry defines the region to subset in the grid coverage.</LI> </UL> <p> <strong>Geotools extension:</strong><br> The operation use the default <CODE>CoordinateOperationFactory</CODE> for creating a transformation from the source to the destination coordinate reference systems. If a custom factory is desired, it may be supplied as a rendering hint with the <A HREF="../../../../../org/geotools/factory/Hints.html#COORDINATE_OPERATION_FACTORY"><CODE>Hints.COORDINATE_OPERATION_FACTORY</CODE></A> key. Rendering hints can be supplied to <A HREF="../../../../../org/geotools/coverage/processing/DefaultProcessor.html" title="class in org.geotools.coverage.processing"><CODE>DefaultProcessor</CODE></A>
