Class GeoPropertyIndex<T>

  • Type Parameters:
    T - the property (like land/water or nation)

    public class GeoPropertyIndex<T>
    extends Object
    Fast index to look up properties of the earth surface. It is expected that there is a relatively slow method to look up the property for a certain coordinate and that there are larger areas with a uniform property. This index tries to find rectangles with uniform property and caches them. Rectangles are subdivided, if there are different properties within. (Up to a maximum level, when the slow method is used again.)
