Method Detail

makePoint

public static NZTM2000 makePoint(java.lang.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(java.lang.String gridref)
                       throws GridFormatException

Parse NZMG coordinates into easting and northing distances

Parameters:

gridref - A pair of NZMG coordinates (e.g. "2487100.638 mE 6751049.719 mN), specified in m.

Returns:

Easting and Northing distances (m)

Throws:

GridFormatException - Invalid coordinate format results in a GridFormatException being thrown

f0

public double f0()

Define scale factor

Specified by:

f0 in class TransverseMercator

Returns:

Scale factor at central meridian

phi0

public double phi0()

Define latitude of true origin

Specified by:

phi0 in class TransverseMercator

Returns:

Latitude of true origin (degrees)

n0

public double n0()

Define false northing

Specified by:

n0 in class TransverseMercator

Returns:

False northing value (metres)

e0

public double e0()

False Eastimg (metres)

Specified by:

e0 in class TransverseMercator

Returns:

False easting value (metres)

lamda0

public double lamda0()

The central meridian

Specified by:

lamda0 in class TransverseMercator

Returns:

The central meridian (radians)

defaultEllipsoid

public Ellipsoid defaultEllipsoid()

Define the default Ellipsoid for this system

Specified by:

defaultEllipsoid in class CoordinateSystem

Returns:

Ellipsoid.GRS80

defaultDatum

public Datum defaultDatum()

Description copied from class: CoordinateSystem

Get the defaul Datum for an instance of CoordinateSystem. For example, instances of OSGB usually use the OSGB 1936 datum.

Specified by:

defaultDatum in class CoordinateSystem

Returns:

The default Datum used by this instance of CoordinateSystem

toString

public java.lang.String toString()

Description copied from class: CoordinateSystem

Provide a String representing the position in a correct format for the CoordinateSystem

Specified by:

toString in class CoordinateSystem

Returns:

String
