public class DefaultGeocentricCRS

extends AbstractSingleCRS

implements org.opengis.referencing.crs.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(org.opengis.referencing.crs.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.
