The SCAR Composite Gazetteer of Antarctica (CGA), as the name suggests, is a composite or collection of all those names of features that have been submitted by representatives of national gazetteers. It includes the names of features south of 60° S, both terrestrial and undersea or under-ice. The CGA is a compilation of recognized features, with a numerical Unique Identifier code (UID) assigned to each of them, jointly with a list of applicable place names. The CGA is compiled purely for the convenience of the scientific community and has no legal authority or standing.
Since 2008, Italy and Australia jointly have managed the CGA, the former taking care of the editing, the latter maintaining database and website. The SCAR Standing Committee on Antarctic Geographic Information (SCAGI) coordinates the project.
