/**
 * A {@linkplain org.opengis.referencing.operation.Conversion conversion} transforming
 * (longitude,latitude) coordinates to cartesian coordinates
 * (x,y). 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.
 *
 * An unofficial list of projections and their parameters can be found there. Most projections expect the
 * following parameters: "semi_major" (mandatory), "semi_minor"
 * (mandatory), "central_meridian" (default to 0), "latitude_of_origin"
 * (default to 0), "scale_factor" (default to 1), "false_easting" (default
 * to 0) and "false_northing" (default to 0).
