All Implemented Interfaces:

Serializable

public class CompoundCRS
extends CoordinateSystem

A CompoundCRS is a GeographicCRS with a third axis (the height axis) attached. This axis denotes a vertical axis, which defines a unit for a given height above or below the datums surface.

Constructor Detail

CompoundCRS

public CompoundCRS(Axis heightAxis,
                   CoordinateSystem underlyingCRS,
                   double defaultHeight,
                   Identifiable identity)
            throws IllegalArgumentException

Parameters:

heightAxis - defining the name and the units of the 'vertical' axis

underlyingCRS - the crs to which the height axis is added, only geographic, geocentric or projected crs are valid.

defaultHeight - of the any coordinate which does not have a height-axis-value.

identity - containing the identifiable values.

Throws:

IllegalArgumentException - if the underlying crs is not of type geographic, geocentric or projected or one of the other values is null.

Method Detail

getDimension

public int getDimension()

Specified by:

getDimension in class CoordinateSystem

Returns:

the dimension of this CRS.

getType

public final int getType()

Specified by:

getType in class CoordinateSystem

Returns:

one of the *_CRS types defined in this class.

getHeightAxis

public final Axis getHeightAxis()

Returns:

the heightAxis.

getHeightUnits

public final Unit getHeightUnits()

Returns:

the units of the heightAxis.

getAxis

public Axis[] getAxis()

Overrides:

getAxis in class CoordinateSystem

the geographic Axis and the heightAxis as the third component.

getUnderlyingCRS

public final CoordinateSystem getUnderlyingCRS()

Returns:

the underlyingCRS.

getDefaultHeight

public double getDefaultHeight()

Returns:

the defaultHeight or 0 if it was not set.
