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 Geotools 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

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.

hashCode

public int hashCode()
Returns a hash value for this geocentric CRS.

Overrides:
hashCode in class AbstractSingleCRS
Returns:
The hash code value. This value doesn't need to be the same in past or future versions of this class.

formatWKT

protected String formatWKT(Formatter formatter)
Format the inner part of a Well Known Text (WKT) element.

Overrides:
formatWKT in class AbstractCRS
Parameters:
formatter - The formatter to use.
Returns:
The name of the WKT element type, which is "GEOCCS".
