The most commonly used kinds of Reference Systems in Apache SIS are the Coordinate Reference Systems (CRS), which handle coordinates of arbitrary dimensions. The SIS implementations can handle 2D and 3D coordinates, as well as 4D, 5D, etc. An other less-frequently used kind of Reference System uses labels instead, as in postal address. This package is the root for both kinds, with an emphasis on the one for coordinates.

AuthorityFactory
method to invoke, while
the code specifies the argument value to give to that method in order to get the EPSG object.
For example the CommonCRS.WGS84
documentation said that object
of type geodetic datum is associated to code EPSG:6326
.
This means that the EPSG object could be obtained by the following code:
The EPSG objects can also be inspected online on the EPSG registry web site.DatumAuthorityFactory factory = ...; // TODO: document how to obtain an EPSG factory. GeodeticDatum datum = factory.createGeodeticDatum("6326");
