    • getModel

      public static org.locationtech.jts.geom.PrecisionModel getModel()
      Gets the precision model for topologies. The model has a precision for locations given by the EPSILON value.
      Returns:
      the precision model.

    • getFactory

      public static org.locationtech.jts.geom.GeometryFactory getFactory()
      Gets the factory for topologies that uses the precision model given by getModel().
      Returns:
      the factory for creating topology objects.

    • createCoordinate

      public static org.locationtech.jts.geom.Coordinate createCoordinate(double x, double y)
      Creates a coordinate for the specified values that conforms to the precision model returned by getModel().
      Parameters:
      x - the coordinate x value.
      y - the coordinate y value.
      Returns:
      the coordinate with values rounded to the precision model accuracy.
