The interactive panoramas website 360Cities has released a new Google Maps interface for interacting with the site's thousands of images.
The new interface uses clustering to reduce the time it takes for the map markers to load. At lower zoom levels numbered markers indicate how many images are available at a location. When you zoom in or click on the numbered markers the individual panorama markers are revealed.
When you click on a marker the interactive panorama replaces the map so that you are able to enjoy the panorama in all its glory. A small map is shown in the bottom left hand corner of the page. As you pan around in the panorama the map shows you the direction of your current view.
This is a a great update from 360Cities. It is now very similar to Google Street View but with much better photography.
