Class ImageCombinerRasterDataSource

java.lang.Object

com.nutiteq.rasterdatasources.AbstractRasterDataSource

com.nutiteq.datasources.raster.ImageCombinerRasterDataSource

All Implemented Interfaces:

com.nutiteq.rasterdatasources.RasterDataSource

public class ImageCombinerRasterDataSource
extends com.nutiteq.rasterdatasources.AbstractRasterDataSource

Data source for combining (blending) multiple source tiles. This can be used to synchronize raster tile displaying (zoom levels of blended tiles always match) and to optimize texture cache usage. Note that the original data sources are queried consecutively, thus if both are high-latency data sources (network sources) then this data sources will have even higher latency.
