Microsoft's been hard at work on enhancing the Bing Maps experience within Windows 8.1, and it all started with the release of a preview application last year. With one of the focus areas being 3D exploring, Bing has announced that Maps Preview can now provide a 360-degree view of 15 more cities, both from the US and abroad. Here in the States, this includes Montgomery, Alabama; San Francisco, California; Tallahassee, Florida; and Seattle, Washington, to mention a few. Meanwhile, in Europe, Bing has added 3D mapping access to Duisburg and Dresden in Germany, as well as Marbella and Murcia in Spain. The Redmond-based outfit says we can expect the list to keep growing, too, as it is always working to support additional places.
