Constructor Detail

LambertII

public LambertII(Position p,
                 Ellipsoid e,
                 Datum d)

Create an instance of LambertII from Position, Ellipsoid and Datum

Parameters:

p - the position of this point

e - The Ellipsoid to use

d - The datum to be used

LambertII

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

Create an instance of LambertII from easting and northing distances, Ellipsoid and Datum

Parameters:

en - Easting and Northing distances

e - Ellipsoid to use

d - Datum to use

Method Detail

makePoint

public static LambertII 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. French convention sometimes includes the zone number as the first digit of the Y (northing) coordinate (e.g. "Y=3210.98" denoting a northing distance of 210.98km in zone 3). If present, this is ignored.

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
