United Kingdom Ordnance Survey in Minecraft

The UK Ordnance Survey:

We have created GB Minecraft 2, a Minecraft® world made with digital map products – freely available as OS OpenData™.

The world consists of more than 83 billion blocks representing over 220,000 square kilometres of mainland Great Britain and surrounding islands. We don’t include Northern Ireland, the Channel Islands or the Isle of Man because they are mapped by other organisations.

Pretty big download (1GB download, 23GB uncompressed), but lots of fun to be had here. Just a shame it’s not to scale – imagine the size if it was though!

Each block represents a ground area of 25 square metres. The raw height data is stored in metres and must be scaled to a suitable resolution. A maximum height of 3,200 metres was chosen, which exaggerates the real-world height by approximately 2.3x, which preserves low-lying coastal features such as Bournemouth’s cliffs, adding interest to the landscape. Dimensionally, each block is more like a cuboid measuring 25 m x 25 m x 12m.
