public class UniversalTransverseMercatorAuto
extends Projection

A map projection is any method used in cartography (mapmaking) to represent the two-dimensional curved surface of the earth or other body on a plane. The term "projection" here refers to any function defined on the earth's surface and with values on the plane, and not necessarily a geometric projection.

Constructor Detail

UniversalTransverseMercatorAuto

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

Creates a new Universal Transverse Mercator Projection based on the given Ellipsoid and parameters.

Parameters:

ellipsoid - ellipsoid used to define the projection.

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

Method Detail

getZone

public int getZone(double[] coord)

transform

public double[] transform(double[] coord)

Transform coord using a Universal Transverse Mercator projection. Input coord is supposed to be a geographic latitude / longitude coordinate in radians.

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 Projection inverse()

Creates the inverse CoordinateOperation.

Specified by:

inverse in interface CoordinateOperation

Overrides:

inverse in class Projection

getSurface

public Projection.Surface getSurface()

Return the Surface type of this Projection.

Specified by:

getSurface in class Projection

Returns:

getProperty

public Projection.Property getProperty()

Return the Property of this Projection.

Specified by:

getProperty in class Projection

Returns:

getOrientation

public Projection.Orientation getOrientation()

Return the Orientation of this Projection.

Specified by:

getOrientation in class Projection

Returns:
