java.lang.Object

com.supermap.services.components.impl.TileMatrixsCalculator

public class TileMatrixsCalculator
extends java.lang.Object

TileMatrix collection calculation class. TileMatrix is split into TileTask assigned to worker in JobRunner. This class calculates a series of TileMatrix based on a cached face. Ask these TileMatrix to cover the surface to cut cache, while minimizing the number to cut cache. (Cut the cache surface is irregular, may be concave polygon)
