@Immutable
public class DefaultGeocentricCRS
extends AbstractSingleCRS
implements GeocentricCRS

A 3D coordinate reference system with the origin at the approximate centre of mass of the earth. A geocentric CRS deals with the earth's curvature by taking a 3D spatial view, which obviates the need to model the earth's curvature.

Used with CS type(s)

Cartesian, Spherical

Field Detail

CARTESIAN

public static final DefaultGeocentricCRS CARTESIAN

The default geocentric CRS with a Cartesian coordinate system. Prime meridian is Greenwich, geodetic datum is WGS84 and linear units are metres. The X axis points towards the prime meridian. The Y axis points East. The Z axis points North.

SPHERICAL

public static final DefaultGeocentricCRS SPHERICAL

The default geocentric CRS with a spherical coordinate system. Prime meridian is Greenwich, geodetic datum is WGS84 and linear units are metres.

Constructor Detail

DefaultGeocentricCRS

public DefaultGeocentricCRS(GeocentricCRS crs)

Constructs a new geocentric CRS with the same values than the specified one. This copy constructor provides a way to wrap an arbitrary implementation into a Geotk 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.

Since:

2.2

DefaultGeocentricCRS

public DefaultGeocentricCRS(String name,
                            GeodeticDatum datum,
                            CartesianCS cs)

Constructs a geocentric CRS from a name.

Parameters:

name - The name.

datum - The datum.

cs - The coordinate system.

DefaultGeocentricCRS

public DefaultGeocentricCRS(String name,
                            GeodeticDatum datum,
                            SphericalCS cs)

Constructs a geocentric CRS from a name.

Parameters:

name - The name.

datum - The datum.

cs - The coordinate system.

DefaultGeocentricCRS

public DefaultGeocentricCRS(Map<String,?> properties,
                            GeodeticDatum datum,
                            CartesianCS cs)

Constructs a geographic CRS from a set of properties. The properties are given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

datum - The datum.

cs - The coordinate system.

DefaultGeocentricCRS

public DefaultGeocentricCRS(Map<String,?> properties,
                            GeodeticDatum datum,
                            SphericalCS cs)

Constructs a geographic CRS from a set of properties. The properties are given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

datum - The datum.

cs - The coordinate system.

Method Detail

wrap

public static DefaultGeocentricCRS wrap(GeocentricCRS object)

Returns a Geotk CRS 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 Geotk implementation, then the given object is returned unchanged. Otherwise a new Geotk implementation is created and initialized to the attribute values of the given object.

Parameters:

object - The object to wrap in a Geotk implementation, or null if none.

Returns:

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

Since:

3.18

getDatum

public GeodeticDatum getDatum()

Returns the datum.

Specified by:

getDatum in interface GeodeticCRS

Specified by:

getDatum in interface SingleCRS

Overrides:

getDatum in class AbstractSingleCRS

Returns:

The datum.

formatWKT

public String formatWKT(Formatter formatter)

Formats the inner part of a Well Known Text (WKT) element.

Specified by:

formatWKT in interface Formattable

Overrides:

formatWKT in class AbstractCRS

Parameters:

formatter - The formatter to use.

Returns:

The name of the WKT element type, which is "GEOCCS".
