Google Street view is a brilliant technology powered by Google Maps, which allows you to explore three dimensional street level imagery of popular locations and places. Using street view, you can have a clear idea how a street looks to human eyes; as the photos are stitched into a complete 3D panoramic view.
A few weeks back, Google Maps added 3d Helicopter view in its driving directions inventory, which is again a very useful feature. You can get transit information between two locations and explore 3D satellite imagery of the entire route; this helps when you want to know the topography and landscape of the path you will travel on.
If you want to explore street view images between any two nearby cities frame by frame, here is a unique Google Maps mash up which you might find interesting.
RCZ View is a web based Google Maps application which lets you watch a stop motion video animation of street view images between two nearby cities. Just enter the address of two cities (separated by a maximum distance of 20 Kilometers ) and the app will grab all the street view images between these points. Next, the app will produce a stop motion video animation of the entire scenery, so you can have a real life virtual view of the travelling route. [ see example]
RCZ view takes you on a virtual car ride, it feels like you are sitting inside a car and exploring the outside world with Google Maps lenses. Watch the following video to learn how RCZ View works:
The RCZ view website is an advertising campaign launched by Peugot to promote the sales of their Peugot Rcz sports car, so I am not sure how long this application will last. The routes are limited for US and European countries only.
