makePoint
public static Lambert93 makePoint(java.lang.String gridref, Ellipsoid e, Datum d) throws GridFormatException
Static factory method to create an instance of Lambert93 from a grid reference String- Parameters:
gridref
- A grid reference of the form "X=... Y=..." where the values are easting and northing distances in km.e
- Ellipsoid to use in conversionsd
- Datum to use in conversions- Returns:
- A new LambertI instance
- Throws:
GridFormatException
- thrown in case of format error in the grid reference
-
defaultDatum
public Datum defaultDatum()
