EDINA has updated the most detailed maps in Geology Digimap to the latest version from the British Geological Survey (BGS). The 1:50,000 scale maps and data in Geology Roam and Geology Download are now the DiGMapGB-50 Version 7 data from the BGS.

The main differences between this data and the previous versions is that there is an extra tile of data in Wales, EW150 Dinas Mawddwy, and that the linear features are now contained in a single shapefile rather than being in several separate layers. The 7 different linear feature layers; Alteration, Fault, Fold Axis, Fossil Horizon, Landform, Mineral Vein, and Rock are now all combined in a single Linear layer.

The following tiles have all undergone major changes:

Scotland

• SC008E_Loch Doon (Superficial)
