360Cities.net Virtual Panorama Tours
360cities.net uses Google Maps to display locations in virtual interactive panorama tours. A virtual tour is an embeddable Immersive Tour Widget that you can create using the 360 Cities site. Then you can embed it easily into a web page just like you would a YouTube video.
You can explore any location on the map by clicking a map marker, which opens a spherical interactive panorama. Hotspots in the panorama allow you to move seamlessly to other locations. The virtual tour uses the Google Maps Flash API to display a small floor plan with nearby map markers and a radar view to give you an idea in which direction you are currently looking.
