@Immutable public class GeocentricTranslation
extends PositionVector7Param
extends PositionVector7Param

The provider for "Geocentric translation" (EPSG:9603). This is a special case of "Position Vector 7-param. transformation" where only the translation terms can be set to a non-null value.

In addition to the EPSG parameters, this provider defines some OGC/Geotk-specific parameters. Those parameters begin with the "src_" or "tgt_" prefix, and modify the math transform as below:

If a "src_*" parameter is present, then an EllipsoidToGeocentric transform will be concatenated before the geocentric translation.
If a "tgt_*" parameter is present, then an GeocentricToEllipsoid transform will be concatenated after the geocentric translation.

The following table summarizes the parameters recognized by this provider. For a more detailed parameter list, see the PARAMETERS constant.
