Method Summary

Modifier and Type	Method and Description
static GridCoverage2D	affine(GridCoverage2D coverage, Interpolation interpolation, AffineTransform affineTransform, double[] bkgValues, boolean useInputSampleDimensions, GridCoverageFactory gridCoverageFactory, Hints hints) Apply an affineTransformation to a GridCoverage
static double[]	colorToArray(Color color)
static GridCoverage2D	crop(GridCoverage2D coverage, GeneralEnvelope destinationEnvelope, boolean doReprojection, double[] backgroundValues, Hints hints) Crop a coverage on a specified destination Envelope
static List<GridCoverage2D>	displace(List<GridCoverage2D> coverages, ProjectionHandler handler, GeneralEnvelope destinationEnvelope, CoordinateReferenceSystem sourceCRS, CoordinateReferenceSystem targetCRS, GridCoverageFactory gridCoverageFactory) Displaces a list of coverages, using a ProjectionHandler to eventually split into proper envelopes.
static List<GridCoverage2D>	forceToValidBounds(List<GridCoverage2D> coverages, ProjectionHandler handler, double[] bgValues, CoordinateReferenceSystem targetCRS, Hints hints) Forces an input list of coverages to the valid bounds of the provided target CRS, when a reprojection is needed, using a ProjectionHandler.
static GridCoverage2D	mosaicSorted(List<GridCoverage2D> coverages, GeneralEnvelope destinationEnvelope, double[] bgValues, Hints hints) Mosaic coverages with a preliminary sorting by size
static void	removeNotIntersecting(List<GridCoverage2D> coverages, GeneralEnvelope destinationEnvelope) After reprojection or displacement we could have some coverage that are completely out of the destination area (due to numerical issues their source bbox was interesting the request area, but their reprojected version does not).
static GridCoverage2D	reproject(GridCoverage2D coverage, CoordinateReferenceSystem destinationCRS, Interpolation interpolation, GeneralEnvelope destinationEnvelope, double[] bkgValues, GridCoverageFactory gridCoverageFactory, Hints hints) Reproject a coverage to the specified destination, eventually adding a ROI if missing
static List<GridCoverage2D>	reproject(List<GridCoverage2D> coverages, CoordinateReferenceSystem destinationCRS, Interpolation interpolation, GeneralEnvelope destinationEnvelope, double[] bkgValues, GridCoverageFactory gridCoverageFactory, Hints hints) Reproject the specified list of coverages

                                      throws FactoryException

Reproject the specified list of coverages

Throws:

FactoryException

reproject

public static GridCoverage2D reproject(GridCoverage2D coverage,
                                       CoordinateReferenceSystem destinationCRS,

                                throws FactoryException

Reproject a coverage to the specified destination, eventually adding a ROI if missing

Throws:

FactoryException

colorToArray

public static double[] colorToArray(Color color)

removeNotIntersecting

public static void removeNotIntersecting(List<GridCoverage2D> coverages,
                                         GeneralEnvelope destinationEnvelope)

After reprojection or displacement we could have some coverage that are completely out of the destination area (due to numerical issues their source bbox was interesting the request area, but their reprojected version does not). Cleanup the ones completely out.

displace

public static List<GridCoverage2D> displace(List<GridCoverage2D> coverages,
                                            ProjectionHandler handler,
                                            GeneralEnvelope destinationEnvelope,
                                            CoordinateReferenceSystem sourceCRS,
                                            CoordinateReferenceSystem targetCRS,
                                            GridCoverageFactory gridCoverageFactory)
                                     throws FactoryException,
                                            TransformException

Displaces a list of coverages, using a ProjectionHandler to eventually split into proper envelopes.

Throws:

FactoryException

TransformException
