                         Ellipsoid e,
                         Datum d)

Create an instance of LambertIIExtended from Position, Ellipsoid and Datum

Parameters:

p - the position of this point

e - The Ellipsoid to use

d - The datum to be used

LambertIIExtended

public LambertIIExtended(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 LambertIIExtended makePoint(java.lang.String gridref,
                                          Ellipsoid e,
                                          Datum d)
                                   throws GridFormatException

Static factory method to create an instance of LambertII 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.
