Building a 3D map of London

Have you seen the fantastic 3D model map of London at The Building Centre yet? We popped in to see it in early May, but that was ahead of the full interactive display being live over the map. It’s all up and running now and our colleague Danny Hyam, who was also involved in putting the map and data together, took some great photos.

London 3D map

The New London Architecture (NLA) team’s model map was built by Pipers, with data supplied by us at OS, using a combination of laser-cutting, 3-D printing and hand-crafting. For our part we supplied all of the mapping that sits underneath the 3D model. The huge 12.5m long map was produced at a 1:2000 scale using our OS MasterMap Topography Layer. The maps were supplied in 64 sections that were then pieced together to build the London map.

The model includes more than 85 km2 of London, 19 boroughs and around 170,000 buildings. It extends from King’s Cross in the north to Peckham in the south and the Royal Docks in the east to Old Oak Common in the west.

As well as providing the map that the model sits on, we used our databases and products to highlight details about the city. These ranged from the 530 km of roads snaking across London to the 1,387,473 residential addresses to showing all of the hospitals. We also created thematic maps using ONS and Land Registry data.

There are video displays and touchscreens to explain the project in detail, and show the key areas of change, revealing the sheer scale of proposed development in the capital. Something as visual and striking as this underlines the use of data and solutions to underpin the work of developers, the insurance and legal industries as well as transport planners.

The free exhibition at The Building Centre is open until next year. Visit their website for directions and opening hours.
