Constructor Detail

NewZealandMapGrid

public NewZealandMapGrid(Ellipsoid ellipsoid,
                         Map<String,Measure> parameters)

Create a new New Zealand Map Grid Projection corresponding to the Ellipsoid and the list of parameters given in argument and initialize common parameters lon0, lat0, FE, FN and other parameters useful for the projection.

Parameters:

ellipsoid - ellipsoid used to define the projection.

parameters - a map of useful parameters to define the projection.

Method Detail

getSurface

public Projection.Surface getSurface()

Return the Surface type of this Projection.

Specified by:

getSurface in class Projection

getProperty

public Projection.Property getProperty()

Return the Property of this Projection.

Specified by:

getProperty in class Projection

getOrientation

public Projection.Orientation getOrientation()

Return the Orientation of this Projection.

Specified by:

getOrientation in class Projection

transform

public double[] transform(double[] coord)
                   throws CoordinateDimensionException

Transform coord using the New Zealand Map Grid Projection. Input coord is supposed to be a geographic latitude / longitude coordinate in radians. Algorithm based on the USGS professional paper 1395, "Map Projection - A Working Manual" by John P. Snyder :

Specified by:

transform in interface CoordinateOperation

Specified by:

transform in class AbstractCoordinateOperation

Parameters:

coord - coordinate to transform

Returns:

a double array containing the output coordinate

Throws:

CoordinateDimensionException - if coord length is not compatible with this CoordinateOperation.

inverse

public CoordinateOperation inverse()
                            throws NonInvertibleOperationException

Creates the inverse operation for New Zealand Map Grid Projection. Input coord is supposed to be a projected easting / northing coordinate in meters. Algorithm based on the USGS professional paper 1395, "Map Projection - A Working Manual" by John P. Snyder :

Specified by:

inverse in interface CoordinateOperation

Overrides:

inverse in class AbstractCoordinateOperation

Parameters:

coord - coordinate to transform

Throws:

NonInvertibleOperationException
