    • forward_impl

      protected abstract Point2D forward_impl(double lat, double lon, Point2D mapPoint)
      Deprecated.
      Worker method to be overridden by derived class. Performs the pure transformation. Prescaling, northing, easting etc is calculated in this class.
      Parameters:
      lat - latitude of source location
      lon - longitude of source location
      mapPoint - point on the map
      Returns:
      the map coordinate

    • inverse_impl

      protected abstract GeoPos inverse_impl(double x, double y, GeoPos geoPoint)
      Deprecated.
      Worker method to be overridden by derived class. Performs the pure transformation. Prescaling, northing, easting etc is calculated in this class.

      Should be overridden in order to perform transformation in 64-bit accuracy.

      The default implementation simple returns inverse_impl((float)x, (float)y, geoPoint).

      Parameters:
      x - map x coordinate
      y - map y coordinate
      geoPoint - point on the earth's surface
      Returns:
      the geodetic co-ordinate
