Text labels for most of the buttons, Controls accessible while still allowing the map to be the focus of the page.
These improvements are being rolled out to all of Bing's international sites with appropriate market-specific functionality. For example, Bing Maps users in the UK will still have access to the London Street Map and Ordnance Survey styles, along with our standard Road map, via the vector style drop-down. The public transport overlay, showing tube, DLR, and tram networks, is also readily available from the navigation bar when the map is centered over the greater London area.
Improved access to these imagery types by making them directly accessible from the top of the navigation bar. At the same time, you can now more easily switch between various road and imagery styles with a single click.
