      public static NZTM2000 makePoint(String gridref, Ellipsoid e, Datum d) throws GridFormatException
      Static factory method to create an instance of NZMG from a grid reference String
      Parameters:
      gridref - A grid reference of the form "157203 mE 6752091 mN " where the values are easting and northing distances in m
      e - Ellipsoid to use in conversions
      d - Datum to use in conversions
      Returns:
      A new LambertI instance
      Throws:
      GridFormatException - thrown in case of format error in the grid reference

    • getEN

      protected static ENPair getEN(String gridref) throws GridFormatException
