mccombe.mapping.Lambert93

public class Lambert93
extends Lambert

A non-abstract class implementing the Lambert Conformal Conical (LCC) projection for the French Lambert-93 system. Unlike previous French LCC implementations, this one uses GRS80/WGS84 ellipsoid and datum by default.

Parameters:

p - the position of this point

e - The Ellipsoid to use

d - The datum to be used

Lambert93

public Lambert93(ENPair en,
                 Ellipsoid e,
                 Datum d)

Parameters:

en - Easting and Northing distances

e - Ellipsoid to use

d - Datum to use

Method Detail

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.
