Microsoft's mapping API
Microsoft provides an interface to their mapping services as well. Their mapping service previously was referred to as Virtual Earth, but they have since re-branded it as Bing Maps . Hence, in OpenLayers, the Layer Class is called VirtualEarth, and we use it the same way we've created Google and Yahoo! layers.
