AirPressureCoordinateSystem

public AirPressureCoordinateSystem(visad.Gridded1DSet pressure,
                                   visad.Gridded1DSet altitude)
                            throws visad.VisADException,
                                   java.rmi.RemoteException

Constructs from a set of Pressure-s and a set of Altitude-s. The reference RealTupleType will be that of the altitude set. The unit of the pressure coordinate will be the actual unit of pressure in the pressure set.

Parameters:

pressure - A set of Pressure-s.

altitude - A set of Altitude-s.

Throws:

visad.VisADException - VisAD failure.

java.rmi.RemoteException - Java RMI failure.

Method Detail

toReference

public double[][] toReference(double[][] pressures)
                       throws visad.VisADException

Converts from pressures to altitudes.

Specified by:

toReference in class visad.CoordinateSystem

Parameters:

pressures - The pressures to be converted in units of getCoordinateSystemUnits()[0]. Only pressures[0] is used. It may be overwritten.

Returns:

Altitudes in units of getReferenceUnits()[0] corresponding to the input pressures.

Throws:

visad.VisADException - VisAD failure.

fromReference

public double[][] fromReference(double[][] altitudes)
                         throws visad.VisADException

Converts to pressures from altitudes.

Specified by:

fromReference in class visad.CoordinateSystem

Parameters:

altitudes - The altitudes to be converted in units of getReferenceUnits()[0]. Only altitudes[0] is used. It may be overwritten.

Returns:

Pressures in units of getCoordinateSystemUnits()[0] corresponding to the input altitudes.

Throws:

visad.VisADException - VisAD failure.

toReference

public float[][] toReference(float[][] pressures)
                      throws visad.VisADException

Converts from pressures to altitudes.

Overrides:

toReference in class visad.CoordinateSystem

Parameters:

pressures - The pressures to be converted in units of getCoordinateSystemUnits()[0]. Only pressures[0] is used. It may be overwritten.

Returns:

Altitudes in units of getReferenceUnits()[0] corresponding to the input pressures.

Throws:

visad.VisADException - VisAD failure.

fromReference

public float[][] fromReference(float[][] altitudes)
                        throws visad.VisADException

Converts to pressures from altitudes.

Overrides:

fromReference in class visad.CoordinateSystem

Parameters:

altitudes - The altitudes to be converted in units of getReferenceUnits()[0]. Only altitudes[0] is used. It may be overwritten.

Returns:

Pressures in units of getCoordinateSystemUnits()[0] corresponding to the input altitudes.

Throws:

visad.VisADException - VisAD failure.

equals

public boolean equals(java.lang.Object obj)

Indicates if this instance is semantically idential to another object.

Specified by:

equals in class visad.CoordinateSystem

Parameters:

obj - The other object.

Returns:

True if an only if this instance is sematically equall to obj.
