Google has now incorporated StreetView images into driving directions. This is another practical application of the street-level photography. Earlier I wrote about its adoption by real-estate vertical Trulia and other “practical” implementations of StreetView.
At many steps of the way StreetView images are available to “disambiguate” directions (camera icons indicate the availability of images). Here are some sample images for a hypothetical trip from the Claremont Hotel in Berkeley CA to the famous “Cliff House” in San Francisco:
Assuming images are available, one could potentially “walk” the entire way from A to B using StreetView.
