| /** |
| * A 3-dimensional 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 3-dimensional spatial view, which obviates |
| * the need to model the earth's curvature. |
| * |
| * <p><b>Used with datum type:</b> |
| * {@linkplain org.apache.sis.referencing.datum.DefaultGeodeticDatum Geodetic}.<br> |
| * <b>Used with coordinate system types:</b> |
| * {@linkplain org.apache.sis.referencing.cs.DefaultCartesianCS Cartesian} or |
| * {@linkplain org.apache.sis.referencing.cs.DefaultSphericalCS Spherical}. |
| * </p> |
| * |
| * <h2>Creating new geocentric CRS instances</h2> |
| * New instances can be created either directly by specifying all information to a factory method (choices 3 |
| * and 4 below), or indirectly by specifying the identifier of an entry in a database (choices 1 and 2 below). |
| * Choice 1 in the following list is the easiest but most restrictive way to get a geocentric CRS. |
| * The other choices provide more freedom. |
| * |
| * <ol> |
| * <li>Create a {@code GeocentricCRS} from one of the static convenience shortcuts listed in |
| * {@link org.apache.sis.referencing.CommonCRS#geocentric()}.</li> |
| * <li>Create a {@code GeocentricCRS} from an identifier in a database by invoking |
| * {@link org.apache.sis.referencing.factory.GeodeticAuthorityFactory#createGeocentricCRS(String)}.</li> |
| * <li>Create a {@code GeocentricCRS} by invoking the {@code CRSFactory.createGeocentricCRS(…)} method |
| * (implemented for example by {@link org.apache.sis.referencing.factory.GeodeticObjectFactory}).</li> |
| * <li>Create a {@code GeocentricCRS} by invoking the |
| * {@linkplain #DefaultGeocentricCRS(Map, GeodeticDatum, CartesianCS) constructor}.</li> |
| * </ol> |
| * |
| * <b>Example:</b> the following code gets a geocentric CRS using the <cite>World Geodetic System 1984</cite> datum: |
| * |
| * {@preformat java |
| * GeodeticDatum datum = CommonCRS.WGS84.geocentric(); |
| * } |
| * |
| * <h2>Immutability and thread safety</h2> |
| * This class is immutable and thus thread-safe if the property <em>values</em> (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. |
