Digital Geological Map Data of Great Britain - 25k (DiGMapGB-25) Bedrock version 2
Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:25 000 scale providing bedrock geology. Onshore coverage is partial and BGS has no intention to create a national coverage at this scale. Areas covered are essentially special areas of 'classic' geology and include Llandovery (central Wales), Coniston (Lake District) and Cuillan Hills (Isle of Skye). Bedrock geology describes the main mass of solid rocks forming the earth's crust. Be
