Interface RasterData

  • All Known Implementing Classes:
    JGrassRasterData
    public interface RasterData

    Interface describing a raster map for JGrass internal usage.

    This was thought instead of the direct data matrix usage in order to be able to migrate to the coverage standard at some point.
