re: Granted..but 2 years old?
Those aerial photographs are property surveys, usually commissioned by a government agency which has some initial control over how they're used, and all of the control over when the next survey of the same land is done.
Very often, in parts of the US undergoing new development, Google Earth (and Maps) displays the paths and names of streets and roads overlaid on photos of open land -- roads that have been graded, paved, and occupied with homes and shopping centers long before the photos are updated.
