There's a new world map for Minecraft that features more tha 224,000sq km (86,000sq miles) of Great Britain, and it only took two weeks to construct.

Map-maker Ordnance Survey - led by intern Joseph Braybrook and the company's Innovation Labs team - used its own Open Data terrain tech to meticulously build an accurate rendition of Great Britain on Minecraft.

Ordnance Survey’s Innovation Lab manager Graham Dunlop told the BBC that they created the largest Minecraft world ever using real-world data. It took 22 billion Minecraft blocks, resulting in a download packs that weighs 3.6GB, though the impressive feat took but a fortnight to accomplish.

"The resulting map shows the massive potential not just for using Minecraft for computer technology and geography purposes in schools, but also the huge scope of applications for OS OpenData too," Dunlop said.

Minecraft is a sandbox indie game that publicly released for the PC in 2009. Mobile versions of the game are also available. Ordnance Survey's Great Britain map has a starting point at its HQ in Southampton, but the game's 33 million players are free to build worlds on top of the geographically realistic landscape once they enter.
