Have you ever wondered what it's like to rewire a whole city?
This video is an explanation behind the Tunnel Map photo which won 3rd prize in the ZEISS Photography competition at the Department of Engineering 2016. The image shows a two kilometre map, taken in the Wimbledon to Kensal Green arm of National Grid's London Power Tunnels.
Due for completion in 2018, the power tunnel network will channel up to 6 x 400kV electricity cables beneath London, doubling power capacity to the capital.
The image was captured and processed by a low cost robotic device developed by a collaborative project between the Department of Engineering's Centre for Smart Infrastructure and Construction and Toshiba Research.
The device, which makes innovative use of inexpensive commercial digital cameras, takes high-resolution photographs suitable for sub-millimetre inspection of the concrete surface.
The 1.5 terapixel image seen here is pieced together from over 120,000 individual photographs.
Each of the 12 columns in the image spans a distance of 170 metres and shows the full 360 degree tunnel circumference unwrapped.
The use of innovative analysis software, developed as part of the project, enables safer, more efficient and more accurate understanding of the infrastructure's performance over time.
