Google Maps API version 2.104 introduces new classes that allow you to integrate Google Street View into your Google Maps. Google Street View provides 360° horizontal and 290° vertical panoramic views for various streets around the world.
The following demos show how you can use the Google Maps API to integrate a Street View Panorama alongside a Google Map.

This demo uses the GStreetviewClient and GStreetviewPanorama classes. To test, click a street on the Google Map. If the script is able to find a panorama nearby, it will be displayed in the Street View pane. The tool tip in the Google Map pane shows the current panorama title and other panoramas nearby.
