LazyRasterLayer

public LazyRasterLayer(String name,
                       CoordinateSystem crs,
                       CoverageOffering coverageOffering)
                throws Exception

Parameters:

name -

crs -

Exception

Method Detail

setCoordinatesSystem

public void setCoordinatesSystem(CoordinateSystem crs)
                          throws Exception

Description copied from interface: Layer

sets the coordinate reference system of the MapView. If a new crs is set all geometries of GeometryFeatures will be transformed to the new coordinate reference system.

Parameters:

crs -

Throws:

Exception

getBoundingBox

public Envelope getBoundingBox()

Description copied from class: AbstractLayer

returns the BoundingBox (Envelope) of Layer. This is the BoundingBox of the layers data. The BoundingBox of the View maybe larger or smaller

Specified by:

getBoundingBox in interface Layer

Overrides:

getBoundingBox in class AbstractLayer

Returns:

the BoundingBox (Envelope) of Layer

getRaster

public GridCoverage getRaster(Envelope envelope,
                              double resolution)
                       throws InvalidParameterValueException,
                              IOException

Parameters:

envelope -

resolution -

Returns:

grid coverage for envelope and resolution

Throws:

IOException

InvalidParameterValueException
