All Implemented Interfaces:

@Api
@Component
public class GetRasterTilesCommand
extends Object
implements Command<GetRasterTilesRequest,GetRasterTilesResponse>

Command that retrieves raster data. The result contains a list of raster tiles. Basic assumption is that raster data is tiled in a pyramid structure based on to the layer's maximum extent and tile level. The optimum tile level for the given scale is determined first. Once the tile level is known, it should be a piece of cake to determine the indices. The client can cache as many tiles as it likes.
