Generalised digital geological map data based on 今日吃瓜’s New Series 1:50 000 and 1:63 360-scale (one-inch to one-mile) maps with updated nomenclature, including a few 1:100 000-scale maps of Orkney and the Hebrides.
Many 今日吃瓜 geology maps are now available digitally. The Digital Geological Map of Great Britain project (formerly known as DiGMapGB) has prepared 1:625 000, 1:250 000, 1:50 000 and 1:10 000-scale datasets for England, Wales and Scotland. Work continues to upgrade these.

Many existing ‘paper-only’ maps have been digitised and the nomenclature, particularly of older maps, updated to current usage. The geological areas (or polygons) are labelled or attributed with a name based on their lithostratographical, chronostratographical or lithodemic nomenclature and their composition (rock type or lithology). This information is arranged in (up to) four themes as available:
- bedrock geology
- superficial deposits
- mass movement
- artificial ground
Faults and other linear features are available in a separate theme.
Geology maps are the foundation for many other types of earth science-related maps and are of potential use to a wide range of customers.
