◆ crsIdentifier()

String CoordinateProjection::crsIdentifier ( ) const
inline

Constructs a CRS identifier string for this projection.

Returns an "EPSG:<code>" string if the authority is EPSG with a valid authority number, optionally appending a vertical authority number. Falls back to the WKT string if available, or the PROJ4 string otherwise.

Returns
A string identifying this coordinate reference system.
