An enormous 360 degree-view photograph of London which if printed would be almost as big as Buckingham Palace has been unveiled by BT.
The image, made up of 48,000 individual frames, allows users to weave through the city streets, and zoom in up to 20 miles around the capital.
The 320 gigapixel image will delight both beady-eyed Where's Waldo? fans and Londoners, who might zoom in to see themselves in a park or strolling to work.
Taken from the top of the BT Tower, the image has set a new record for the world’s largest panoramic photo.
In comparison, the last record attempt for a London panorama was 80 gigapixels, taken from Centrepoint in 2010.
If printed at normal photographic resolution, the BT Tower panorama would be 98 meters across and 24 meters tall - almost as big as Buckingham Palace.
The panorama was taken by photography firm 360Cities. Photographers took the individual photos over three days, and they were then processed by a computer over three months.
The images were taken using cameras with robotic panorama heads capable of 72,000 steps in a single 360 degree arc, set to fire four frames a second.
The images were taken after the end of London 2012. Londoners, tourists and those who work in the capital are now being asked to share their favourite views of the capital, as a permanent record of London’s year in the global spotlight.
Suzi Williams, director, BT Group Marketing & Brand, said: “The BT Tower is such an iconic London landmark, and became a focus for the capital’s celebrations in 2012, what better way to capture that remarkable year than with a full panoramic photograph taken from its roof.
"This isn’t just a world record for the BT Tower, it’s for London and the people who live, work in or visit the capital. Take a look, and share your favourite London places and landmarks.”
Steve Hercher, director of 360Cities, said: “We were honoured to be chosen by BT to attempt this world record panorama and make our own contribution to commemorating the wonderful London 2012 Games.
"So many unknowns and variables had to be addressed in the planning of this unprecedented shoot, really the first of its kind.
"Software and hardware were pushed to the limits, and rain, wind and other potential stumbling blocks had to be dealt with.
"Our photography team of Jeffrey Martin, Tom Mills and Holger Schulze did an amazing job and not a single individual frame from the more than 48,000 planned was missed.”
