Have you noticed the amazing (and recent) imagery now available on popular real estate website Zillow.com? Simply search a property and obtain a zestimate. then click the "see home info" link provided for the property. You will be returned with a Bird's eye view served up via Microsoft Virtual Earth. The image will be a high-res, accurately geolocated image that rivals that of low-altitude aerial photography... quite cool. Most of the imagery that I saw appears to have been captured within the last year.
