Constructor Detail

LongitudeRotation

public LongitudeRotation(double rotation)

Create a new LongitudeRotation converter.

Parameters:

rotation - rotation angle in radians

Method Detail

transform

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

Return a coordinate representing the same point as coord but in a geographic coordinate system based on a different prime meridian.

Specified by:

transform in interface CoordinateOperation

Specified by:

transform in class AbstractCoordinateOperation

Parameters:

coord - is an array containing 2 or 3 double representing geographic coordinate in the following order : latitude (radians), longitude (radians from Greenwich) and optionnaly ellipsoidal height

Returns:

a double array containing the output coordinate

Throws:

IllegalCoordinateException - if coord is not compatible with this CoordinateOperation.

inverse

public CoordinateOperation inverse()

Creates the inverse CoordinateOperation.

Specified by:

inverse in interface CoordinateOperation

Overrides:

inverse in class AbstractCoordinateOperation

getLongitudeRotationTo

public static LongitudeRotation getLongitudeRotationTo(PrimeMeridian targetPM)

Creates a new LongitudeRotation from Greenwich to this PrimeMeridian.

Parameters:

targetPM - target prime meridian

getLongitudeRotationFrom

public static LongitudeRotation getLongitudeRotationFrom(PrimeMeridian targetPM)

Creates a new LongitudeRotation from this PrimeMeridian to Greenwich.

Parameters:

targetPM - target prime meridian

toString

public String toString()

Return a String representation of this Geographic/Geocentric converter.

Overrides:

toString in class IdentifiableComponent

getRotationAngle

public double getRotationAngle()

equals

public boolean equals(Object o)

Returns true if object is equals to this. Tests equality between the rotationAngles used by the transformation.

Overrides:

equals in class IdentifiableComponent

Parameters:

o - The object to compare this LongitudeRotation against

hashCode

public int hashCode()

Returns the hash code for this LongitudeRotation.

Overrides:

hashCode in class IdentifiableComponent

isIdentity

public boolean isIdentity()

Specified by:

isIdentity in interface CoordinateOperation

Overrides:

isIdentity in class AbstractCoordinateOperation

Returns:

true if this operation does not change coordinates.
