[Editor's note: Yahoo has several nifty tools, including Placemaker, all powered off their GeoPlanet gazetteer, freshly updated in v 1.4 to include links back to other place name gazetteers and even Wikipedia articles, so we (and our machines) can know we're all talking about the same places. Flickr, for instance, stores the geographic tags on photos using GeoPlanet WOEIDs. ]
Back in March at the annual geo-fest that is Where 2.0 in San Jose we released our concordance API as part of Yahoo! GeoPlanet. That initial release allowed conversion between the identifier namespaces of WOEIDs, ISO 3166, FIPS, INSEE, Geonames, JGCD, IATA and ICAO.
Lots of you liked this and asked us to add support for other identifier namespaces as well.
Robert C. Gallagher once said that change is inevitable – except from a vending machine and that works in the Geo world as well. So in version 1.4 of GeoPlanet which is live right now at http://where.yahooapis.com/v1/ you’ll find additional concordance namespace support for
- OpenStreetMap place codes
- Wikipedia place article ids
- UN/Locode place codes
- Country Code Top Level Domain codes
- FAA airport codes
- US and CA ZIP codes
