Last week, Bing unveiled Streetside imaging but you may have noticed it's not quite extensive. Hold your horses. These things take time.
Bing is partnering with Navteq to get some more imaging done. Navteq is already traversing roads all over to get the best info for maps. So, Bing is simply attaching cameras to their vehicles to capture the imaging. Pretty clever.
The vehicles will be outfitted with the Microsoft Vexcel UltraCam. Expect monthly releases of Streetside imagery as it becomes available.
