Model metadata report for the South Downs teaching model

This report describes the South Downs 3D geological model, which was constructed by the British Geological Survey (BGS) using GSI3D software and methodology. The model covers an area of approximately 3,100 km2 from Winchester to Beachy Head in the south of England. Ten bedrock units are modelled, which correspond with the published 1:250 000 scale geological maps of the area. The South Downs model was developed under a BGS project entitled “3D Models for Teaching” and as such is created with a very broad approach to the regional geological understanding, and is intended as a teaching aid for educational purposes
