public class DefaultVerticalCRS
extends AbstractCRS
implements org.opengis.referencing.crs.VerticalCRS

A 1-dimensional coordinate reference system used for recording heights or depths. Vertical CRSs make use of the direction of gravity to define the concept of height or depth, but the relationship with gravity may not be straightforward.

Used with datum type: Vertical.
Used with coordinate system type: Vertical.

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself), the coordinate system and the datum instances given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.

Constructor Details

DefaultVerticalCRS

public DefaultVerticalCRS(Map<String,?> properties,
 org.opengis.referencing.datum.VerticalDatum datum,
 org.opengis.referencing.cs.VerticalCS cs)

Creates a coordinate reference system from the given properties, datum and coordinate system. The properties given in argument follow the same rules than for the super-class constructor. The following table is a reminder of main (not all) properties:

Recognized properties (non exhaustive list)

Property name	Value type	Returned by
"name"	ReferenceIdentifier or String	AbstractIdentifiedObject.getName()
"alias"	GenericName or CharSequence (optionally as array)	AbstractIdentifiedObject.getAlias()
"identifiers"	ReferenceIdentifier (optionally as array)	AbstractIdentifiedObject.getIdentifiers()
"remarks"	InternationalString or String	AbstractIdentifiedObject.getRemarks()
"domainOfValidity"	Extent	AbstractReferenceSystem.getDomainOfValidity()
"scope"	InternationalString or String	AbstractReferenceSystem.getScope()

Parameters:

properties - the properties to be given to the coordinate reference system.

datum - the datum.

cs - the coordinate system.

DefaultVerticalCRS

protected DefaultVerticalCRS(org.opengis.referencing.crs.VerticalCRS crs)

Constructs a new coordinate reference system with the same values than the specified one. This copy constructor provides a way to convert an arbitrary implementation into a SIS one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API.

This constructor performs a shallow copy, i.e. the properties are not cloned.

Parameters:

crs - the coordinate reference system to copy.

See Also:

• castOrCopy(VerticalCRS)

Method Details

castOrCopy

public static DefaultVerticalCRS castOrCopy(org.opengis.referencing.crs.VerticalCRS object)

Returns a SIS coordinate reference system implementation with the same values than the given arbitrary implementation. If the given object is null, then this method returns null. Otherwise if the given object is already a SIS implementation, then the given object is returned unchanged. Otherwise a new SIS implementation is created and initialized to the attribute values of the given object.

Parameters:

object - the object to get as a SIS implementation, or null if none.

Returns:

a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.

getInterface

public Class<? extends org.opengis.referencing.crs.VerticalCRS> getInterface()

Returns the GeoAPI interface implemented by this class. The SIS implementation returns VerticalCRS.class.

Note for implementers: Subclasses usually do not need to override this method since GeoAPI does not define VerticalCRS sub-interface. Overriding possibility is left mostly for implementers who wish to extend GeoAPI with their own set of interfaces.

Overrides:

getInterface in class AbstractCRS

Returns:

VerticalCRS.class or a user-defined sub-interface.

getDatum

public org.opengis.referencing.datum.VerticalDatum getDatum()

Returns the datum.

Specified by:

getDatum in interface org.opengis.referencing.crs.SingleCRS

Specified by:

getDatum in interface org.opengis.referencing.crs.VerticalCRS

Returns:

the datum.

getCoordinateSystem

public org.opengis.referencing.cs.VerticalCS getCoordinateSystem()

Returns the coordinate system.

Specified by:

getCoordinateSystem in interface org.opengis.referencing.crs.CoordinateReferenceSystem

Specified by:

getCoordinateSystem in interface org.opengis.referencing.crs.SingleCRS

Specified by:

getCoordinateSystem in interface org.opengis.referencing.crs.VerticalCRS

Overrides:

getCoordinateSystem in class AbstractCRS

Returns:

the coordinate system.

forConvention

public DefaultVerticalCRS forConvention(AxesConvention convention)

Returns a coordinate reference system equivalent to this one but with axes rearranged according the given convention. If this CRS is already compatible with the given convention, then this method returns this.

Overrides:

forConvention in class AbstractCRS

Parameters:

convention - the axes convention for which a coordinate reference system is desired.

Returns:

a coordinate reference system compatible with the given convention (may be this).

See Also:

• AbstractCS.forConvention(AxesConvention)

formatTo

protected String formatTo(Formatter formatter)

Formats this CRS as a Well Known Text VerticalCRS[…] element.

Overrides:

formatTo in class AbstractCRS

Parameters:

formatter - the formatter where to format the inner content of this WKT element.

Returns:

"VerticalCRS" (WKT 2) or "Vert_CS" (WKT 1).
