Note: Compilation project by UBSS, with individuals editing a common dataset through SVN. Increased activity due to the major extension to Charterhouse Cave in 2009. Used Therion for the main Charterhouse/
GB map and with the MCG Therion version of Upper Flood and the import of Survex and compass data, producing an overall 3D model. Further information, acknowledgements and the latest released output on the ubss website
