Google Earth, the company's interactive mapping program, has conjured up 3D representations of London landmarks in time for the royal wedding of Prince William and Kate Middleton on Friday.
After the royal couple has tied the knot, they will set off by coach for a procession through the streets of London. People around the world can check out the wedding route in 3D from the comfort of their own armchairs, using the Google Maps add-on.
The route begins at Westminster Abbey in Parliament Square, the traditional venue for royal weddings and coronations.
The latest version of the program, Google Earth version 6, is available for download from Google's site, and offers a combination of worldwide satellite imagery, 3D graphics and street-level pictures via Google Street View.
Alternatively, people can view Google Earth via a browser by installing a plug-in.
Above, the royal procession will proceed up Whitehall, past the Cenotaph and Downing Street.
Pictured above is Horse Guards Parade, St James's Park and, in the distance, Buckingham Palace.
Google Earth is available in free, Pro and Enterprise editions. The Pro version adds 3D measurements, a film-making function, and the ability to import image files and addresses, while the Enterprise software is designed to help companies build globes and imagery from their own geographical data.
Buckingham Palace is the end point of the royal procession. According to Google, the 3D images of St James's Park have been modelled to include five different species of tree, and contain more than 12,000 individual trees.
Google Earth 3D includes an array of other buildings in central London, such as the yet-to-be-completed Shard building in London Bridge (above). With 72 floors, the Shard will be the tallest building in Europe when it is completed in 2012.
