Using Bing imagery


Bing Maps, previously known as Virtual Earth, is the mapping service provided by Microsoft.

In the same way as Google Maps, OpenLayers offers an OpenLayers.Layer.Bing class, which brings us the possibility to add Bing imagery in our projects.

Getting ready

Bing Maps requires you to register as a consumer user. Once registered, you will get an API key needed to initialize the OpenLayers.Layer.Bing layer and that will be used with every request to authenticate you against the Bing Maps service.

Note

You can find out how to register as a user at http://msdn.microsoft.com/en-us/library/ff428642.aspx.
