I’ve just uploaded a spreadsheet of country codes (plain HTML view) to Google documents and spreadsheets. The spreadsheet includes ISO 3166-1 alpha-2, alpha-3, and numeric codes together with FIPS 10-4 codes, and the country names as provided in each spec. I originally created it to help me map FIPS to ISO codes from some air navigation data.
I’m interested in online data collaboration — what tools people need, how it will work in practice, etc. — and this seems like an easy way to experiment. If you’d like to make any corrections to the spreadsheet, let me know, and I’ll add you as a collaborator. I might also upload some spreadsheets of general geodata in the future, where there’s more opportunity for contributions.
Cool. How about adding the supranational regions, which share the numeric code space? I’ll add them if you set me up.
