Yandex adds Public (Crowdsourced) Maps
Yandex, one of Russia's top Internet portals, announced on March 5 that it has integrated maps of some 40 cities in Russia, Ukraine, Belarus and Kazakhstan created by its users to Yandex.Maps. If "professional" maps of an area are not avaiable, the Pubilc Maps are returned instead. In other areas, where both maps are available, the user can select which layer to view. Users can also edit and submit new data to the Public Map.
Is the the "lifecycle" of a mapping portal? Start with commercial data, then mix in user generated (sometimes open, but not always) data, then perhaps go 100% crowdsourced data? Google, MapQuest, Microsoft and now Yandex are heading along something like that trajectory.
