Class TileMatrixsCalculator

  • 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)

    Since:
    6.1.3
