Creating a map with or without directions requires data from a number of sources. The Yahoo! Maps and its partner, Nokia , provide an internal centralized service for all of its processed data – including map tile images, geocoding, routing, traffic data, and mapping information. Traffic.com provides data on real-time traffic.
