/**

 * A {@linkplain org.opengis.referencing.operation.Conversion conversion} transforming

 * (<var>longitude</var>,<var>latitude</var>) coordinates to Cartesian coordinates

 * (<var>x</var>,<var>y</var>). Although some map projections can be represented as a

 * geometric process, in general a map projection is a set of formulae that converts geodetic

 * latitude and longitude to plane (map) coordinates. Height plays no role in this process,

 * which is entirely two-dimensional. The same map projection can be applied to many

 * {@linkplain org.opengis.referencing.crs.GeographicCRS geographic CRSs}, resulting in many

 * {@linkplain org.opengis.referencing.crs.ProjectedCRS projected CRSs} each of which is related

 * to the same {@linkplain org.opengis.referencing.datum.GeodeticDatum geodetic datum} as the

 * geographic CRS on which it was based.

 *

 * <p>An unofficial list of projections and their parameters can

 * be found <a href="http://www.remotesensing.org/geotiff/proj_list/">there</a>.

 * Most projections expect the following parameters:

 *  {@code "semi_major"} (mandatory),

 *  {@code "semi_minor"} (mandatory),

 *  {@code "central_meridian"} (default to 0),

 *  {@code "latitude_of_origin"} (default to 0),

 *  {@code "scale_factor"} (default to 1),

 *  {@code "false_easting"} (default to 0) and

 *  {@code "false_northing"} (default to 0).</p>

 *

 * @departure extension

 *   This interface is not part of the ISO specification. It has been added in GeoAPI at user

 *   request, in order to provide a way to know the kind of map projection.

 *

 * Note: gvSIG derived these interfaces from GeoAPI in order to have a simpler API and also to

 * avoid namespace collisions (e.g. GeoAPI 3 vs GeoTools interfaces). There is no plans

 * to evolve these interfaces to adapt them to future GeoAPI versions.
