Google maps is a feature of google which is probably among one of the most popular services of google. Google maps are so commonly used for navigation and directions, that it is probably the leading map service. It is equally popular on different platforms. Google street view is another feature of google maps which is usually used to see the already captured image of the address or the area around. Now you can navigate and look at direction from one address to another with a series of street views. This automated navigation through street view is  a nice modfication of existing service which is indeed useful.

Here, you put your source and destination addresses. Usually Google maps gives you text directions and highlighted directions on the maps, here you see a autoated navigation system which takes you through a street view as if you are actually charting through the city in real. It is like the service stitches the street views of the location which fall in the path from source to destination addresses. Thus you navigate through different street views to your destination.

You can also select the speed of transition from one street view frame to another. It also gives you the road name as it navigates through the street view, so you are aware of what different streets look like which you are actually going to take.

Although, as expected this service is not perfect. The transition between 1 street view frame to another is not seamless and you sometimes notice a stark change in two frames. Also the fact that street view images taken by google of different places is at different times of the year, so it sometimes seems odd to see the change in street view frames. But the concept is nice and further work on it might lead it to become a nice utility feature where one can navigate through a video like street view navigation to reach the destination.
