Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:625 000 scale providing a simplified interpretation of the geology and may be used as a guide at a regional or national level, but should not be relied on for local geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. The Dykes data defines small, narrow areas (shown as polygons) of a specific type of bedrock geology, igneous rocks which have been intruded into the landscape. The dykes are presented as an optional, separate theme in order to provide additional clarity of the Bedrock theme. The bedrock and dykes datasets are designed to be used together. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are delivered free of charge under the terms of the Open Government Licence.
The version 5 data of the 1: 625 000 dykes data was created primarily from the 1:50 000 scale Digital Geological Map of Great Britain (DiGMapGB-50) version 3 dataset (released in 2006) by generalisation involving cartographic selection, modification, simplification or exaggeration and matches that shown on the BGS poster maps of the UK (North and South) published in 2008. The attributes and nomenclature used follow those on the printed maps.
