Yahoo! GeoPlanet helps bridge the gap between the real and virtual worlds by providing an open, permanent, and intelligent infrastructure for geo-referencing data on the Internet. This page provides open access to the underlying data under a Creative Commons Attribution license so that you can incorporate WOEIDs and the GeoPlanet hierarchy into your own applications. The zip file below contains a license file, a readme file, and three data files in tab-delineated, Unicode (UTF-8) format: 1. geoplanet_places_[version].tsv: the WOEID, the placename, and the WOEID of its parent entity 2. geoplanet_aliases_[version].tsv: alternate names in multiple languages indexed against the WOEID 3. geoplanet_adjacencies_[version].tsv: the entities neighboring each WOEID 4. geoplanet_changes_[version].tsv: the list of removed WOEIDs and their replacement WOEID mappings How Do I Get Started? 1.
