| /** |
| * The provider for <q>sinusoidal equal-area</q> projection. |
| * This is a pseudo-cylindrical (or "false cylindrical") projection. |
| * This projection method has no associated EPSG code. |
| * |
| * <h2>Departure in parameter name compared to GDAL</h2> |
| * As of May 2024, the {@link #CENTRAL_MERIDIAN} parameter name declared on the GDAL web site |
| * is <q>Longitude of projection center</q> for EPSG and <q>longitude_of_center</q> for OGC. |
| * However, EPSG does not define this projection, and OGC names generally follow ESRI names. |
| * The parameter name declared by ESRI for projection ESRI:54030 is <q>Central_Meridian</q>. |
| * This class follows ESRI name for OGC and uses <q>Longitude of natural origin</q> for EPSG. |
| * The latter is the name that we found in usage for WKT 2 strings, is used by PROJ implementation |
| * and seems to be match better the usages in the EPSG geodetic dataset. |
