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 Details

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 Details

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 Details

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.

calculateHashCode

public int calculateHashCode()

Returns a hash value for this geocentric CRS.

Overrides:

calculateHashCode 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".
