CGA, entrusted to Italy by SCAR in 1992.
Now, a 18 years old project, is a
cooperation between the Italian PNRA and the Australian AAD with contributions by all SC-AGI Members
(*) after Brolsma’s work on Larsemann Hills
Just a compilation, however…..
Input data made homogeneous
Transliteration and translation
Association of names to features
Grouping of names around a feature (Unique SCAR ID)
Exclusion of features North of 60°S
Partial inclusion of man-made features
Exclusion of non official names
Inclusion of undersea features
Inclusion of subglacial features
A project started by H.W. Schenke and R. Cervellati at Buenos Aires first SC-AGI meeting (Oct.2007).
Carried out by R. Krocker (AWI) in 6 months.
Set of “proposal for changes” in the CGA, issued in Sept.2008.
Differences in geographical coordinates are partly accounted for by the fact that GEBCO contains point, line and spatial features.
National gazetteers and CGA, on the contrary, contain only point-like features.
The Norwegian reply made a good point.
No other replies.
CGA will include changes only if they are made in the national gazetteers.
Krocker took into consideration 74 geographic features.
Harmonization required changes in the generic term, and/or specific name, and/or coordinates.
7 Countries are involved (ARG, AUS, GBR, NOR, NZL, RUS, USA).
Relevant info circulated and request for comments among Members (30.11.2009)
verified the willingness of SC-AGI’s Members to operate towards an improvement of the coordinates,
obtaining a range of responses from positive to negative or no response at all.
Two main products:
A web-site continuosly updated
Two hard-copy Publications (in 1998 e 2000) plus a Supplement (in 2004) with SCAR’s financial support
Place names areal distribution shows that:
different Countries apparently adopted different approaches.
Russia and USA gazetteers cover all the continent.
claimant Countries seem to be mainly interested in the claimed sector.
other Countries add up comparatively few places names
The practical outcome
CGA is most complete and updated list (as much as practicable) of the existing names.
For every new proposed toponym it is feasible to verify whether the feature has been already named.
AADC of AAD has accomplished the task of moving the CGA data-base into a new server, adding new fields and new search capabilities, fully refurbishing the web site.
Cooperation between Italy and Australia is excellent.
perhaps establishing a task force inside the SC-AGI
