Place-names are an easy way to describe or identify real world locations, much more intuitive to use than for example geographic coordinates. Place-names play an important role in Antarctica, due in part to their historical and political relevance. The manner of Antarctic discovery and mapping, and the lack of a single geographic names authority under the Antarctic Treaty System, have resulted in numerous cases of multiple names for single features, and inconsistent practices in the recognition and use of existing names. The operational and scientific consequences are evident, with the potential for fatal misunderstandings in position reports by sea, air, and land travellers, and ambiguity in describing the location of scientific observations. The fact that place-names are intrinsically related to territorial claims only makes a solution to the problem more difficult.

At the XXII SCAR meeting in Bariloche, Argentina, in 1992, SCAR's then called Working Group on Geodesy and Geographic Information initiated a new programme designed to bring some order to Antarctic toponymy. The specific goals were to develop two new products for the Antarctic community: a compilation of all existing Antarctic place-names, and guidelines for creating new place-names and for the use of existing names.

The programme resulted in the publication of the first edition of the SCAR Composite Gazetteer of Antarctica (SCAR CGA) in 1998. [1]

Today the SCAR CGA holds more than 35 000 entries. It is managed by the Italian Antarctic Programme.
