All Implemented Interfaces:

public abstract class ALcdMultilevelImage
extends ALcdImage

A multilevel image is a collection of ALcdBasicImages which cover the same geographic area and have same ALcdBandSemantics but which can have different resolutions, different sampling modes and/or represent different data. Typically, for visualization, an image is chosen whose spatial resolution best matches the current scale of the view.

The bounds of the multilevel image is the union of the bounds of all its levels. If the level relation ship is ELcdLevelRelationship.OVERVIEW then all levels have the same bounds.

You can obtain a multilevel image from one of the model decoders or using one of the available builders:

• TLcdImageBuilder: basic images and multi-level images
• TLcdRasterImageBuilder: adapt a legacy raster
