public abstract class RasterDataNode extends DataNode implements Scaling, SceneTransformProvider
RasterDataNode
class ist the abstract base class for all objects in the product package that contain
rasterized data. i.e. Band
and TiePointGrid
. It unifies the access to raster data in the
product model. A raster is considered as a rectangular raw data array with a fixed width and height. A raster data
node can scale its raw raster data samples in order to return geophysically meaningful pixel values.Modifier and Type | Class and Description |
