/**
* The provider for "Lambert Azimuthal Equal Area" projection (EPSG:9820, EPSG:1027,
* EPSG:9821).
*
* {@note EPSG defines two codes for this projection, 1027 being the spherical case and 9820 the
* ellipsoidal case. However the formulas are the same in both cases. Consequently they are
* implemented in Geotk by the same class.}
*
* {@note EPSG:9820 and 1027 are the current codes, while EPSG:9821 is a deprecated code. The new
* and deprecated definitions differ only by their names. In the Geotk implementation, both
* current and legacy definitions are known, but the legacy names are marked as deprecated.}
*
* The math transform implementations instantiated by this provider may be any of the following classes:
*
The following table summarizes the parameters recognized by this provider.
* For a more detailed parameter list, see the {@link #PARAMETERS} constant.
