OpenStreetMap is a cartographic project, where maps are created and edited by community forces, much like the articles in the Wikipedia project.
Bing Maps now offers users the option to switch to OpenStreetMap content display mode on the fly. ')
This is a remarkable innovation of Bing Maps, because in countries where the service is not officially launched, the quality of maps suffers greatly. For example, compare the maps of Yekaterinburg in the standard Bing Maps and the new OpenStreetMap layer.
Now, Bing Maps users have an alternative way to view maps. And the new OpenStreetMap layer is fully compatible with all 44 Bing Maps App applications, such as Photosynth, Twitter, Foursquare and others, which add a lot of useful information to maps.
