The Ordnance Survey, the national mapping agency for Great Britain, mapped 220,000 square kilometers of the mainland with 22 billion blocks in Minecraft.
Each blocks represents a ground area of 50 square metres. The raw height data is stored in metres and must be scaled down to fit within the 256 block height limit in Minecraft. A maximum height of 2 500 metres was chosen, which means Ben Nevis, appears just over 128 blocks high. Although this exaggerates the real-world height, it preserves low-lying coastal features such as Bournemouth's cliffs, adding interest to the landscape.
