Dataset Description:

DigRock250 provides offshore geological maps of bedrock geology at 1:250,000 scale, covering the UK coastline and adjacent European waters, in UTM projection.

The bedrock geology theme within DiGMapGB is provided but due to the limitations of surveying techniques offshore, the data is usually much less detailed. Rocks are commonly referred by age (instead of lithostratigraphical nomenclature used onshore), and mapping is usually only to group or formation level at best.
