    • Method Detail

      • getRasterDataNode

        public RasterDataNode getRasterDataNode()
        Returns:
        The target raster data node.

      • getGeophysicalProductData

        protected ProductData getGeophysicalProductData​(RasterDataNode band,
                                                Rectangle region)
        Utility method that allows to retrieve data from a raster data node whose geophysical image shares the same multi-level model (aka image pyramid model).
        Parameters:
        band - A raster data node whose geophysical image shares the same multi-level model.
        region - The region in pixel coordinates of the given resolution level (see SingleBandedOpImage.getLevel()).
        Returns:
        The retrieved pixel data in geophysical units.
