Google has released a video that uses Google Earth to show the Royal Wedding procession route in ’3D’!
The official Google Blog descibes it this way (and sounds rather like a travel agent — their next business perhaps?):
With this new 3D data covering the royal procession route, you can indulge yourself in a “royals’-eye” view to see the same sights that William and Catherine will see. Upon departing Westminster Abbey, you’ll pass the Houses of Parliament and Big Ben, the famous ministries on Whitehall and the Prime Minister’s residence at 10 Downing Street. Traverse Horse Guards Parade, and from there, you can travel down The Mall—with 3D trees lining the route—and see Buckingham Palace standing proudly at the finish. Cool! ( I feel all Royal, all of a sudden!)
