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 me
- 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
-
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 classTransverseMercator
- Returns:
- Scale factor at central meridian
-
phi0
public double phi0()
Define latitude of true origin- Specified by:
phi0
in classTransverseMercator
- Returns:
- Latitude of true origin (degrees)
-
n0
public double n0()
Define false northing- Specified by:
n0
in classTransverseMercator
- Returns:
- False northing value (metres)
-
e0
public double e0()
False Eastimg (metres)- Specified by:
e0
in classTransverseMercator

defaultEllipsoid
in classCoordinateSystem
- Returns:
- Ellipsoid.GRS80
-
defaultDatum
public Datum defaultDatum()
Description copied from class:CoordinateSystem

defaultDatum
in classCoordinateSystem
- 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 classCoordinateSystem
- Returns:
- String
