When Wikidata and OpenStreetMap work together, they create a powerful wealth of knowledge. This integration can power interactive maps on Wikipedia and unlock a wide range of possibilities like translated world maps or thematic maps using information crowdsourced from Wikidata.

In the map above, Arun and Rasagy demonstrate the power of this collaboration with an exploration of country names in various languages of the world.

The geographic shapes of countries are rendered from crowdsourced map data in OpenStreetMap and the corresponding language translations come from live querying the Wikidata entity. This is possible because the country feature on OpenStreetMap is linked to its matching Wikidata entity as an additional property. The lookup is done dynamically and the results improve over time as more Wikidata volunteers contribute country translations.
