Bedrock outcrop polygons have been derived from digitising outcrop locations from scanned 19th Century GSI field maps. The data was derived from mapping at a scale of 1:10,560 (6 inches to one mile). Individual map sheets were geo-referenced to an index polygon and checked against an OSi 1:50,000 raster base for spatial accuracy. This dataset is part of the 100k seamless series
