Free download of the geology of mainland Great Britain as a Minecraft world. The world shows the Ordnance Survey map data on the surface and the rough position of the real geology beneath.
- A licenced copy of Minecraft

You will start at the BGS office in Cardiff. Look around you for signposts with information to get you started. Once you’ve got your bearings you can fly around the landscape by double tapping and holding the spacebar or by teleporting to other parts of the Great Britain geological map.
Illustrating how the geology blocks (such as sand, cobblestone, redstone ore, glowstone, stained clay) are repeated from the bedrock layer up to the elevation model height and OS block (grass block).
Using the methodology developed by the OS, we wrote computer software to programmatically generate the GB geology world in the Anvil file format.
For each 100 x 100 km grid square:
- Load height data from an elevation map of Great Britain, using a modified and scaled version of NEXTMap Britain data
- Load geology data from the BGS 1 km Soil Parent Material dataset
- Load OS VectorMap® District raster files
- Create chunks using the height data to add blocks repeatedly up to the desired height using the real world geology for that location
- For the topmost block, decide the material which matches the OS VectorMap® District data
- Compile groups of 32 x 32 chunks into regions
- Compile all the files together into one ZIP file
To do this, we have used BGS’s Soil Parent Material dataset. A parent material is a soil science name for a weathered rock or deposit from, and within which, a soil has formed. In the UK, parent materials provide the basic foundations and building blocks of the soil, influencing their texture, structure, drainage and chemistry. By using the parent material dataset we can get a general understanding of the types of geology to be found across Great Britain.
Using the methodology developed by the Ordnance Survey, we took the data from the OS VectorMap® District raster to decide the material of each block.
