Data, Information and Knowledge in the British Geological Survey Jeremy Giles
Data Rich • BGS is a data rich organisation • 863,919 onshore boreholes • 7,694 pallets of borehole cores • 138,896 digital borehole logs • 35,755 field slips from geologists • 7,694 lithostratigraphical definitions • 153,752 rock samples • etc. etc.
A Bit of History • BGS has been collecting for 164 years • Oldest records predate BGS • Manual index systems have served for the bulk of that period • Digital systems developed from the bottom up to meet the needs of specific projects • Need to bring control recognised in mid-90s
Data Management • Two projects have been initiated to improve situation • Geoscience Integrated Database System (BGS-geoIDS) • Digital Geoscience Spatial Model (DGSM)
1998 2000 2005 BGS-geoIDS DGSM Time Table
BGS-geoIDS Vision The overall aim of the project is to produce a single unified Corporate database of geoscience information that will enable BGS scientists to undertake R&D more effectively and help BGS to maximise its competitive advantage.
BGS-geoIDS • Compilation of Discovery Metadata • Data Model of Existing System • Data Policy and Management • Desktop Data Delivery
Compilation of Discovery Metadata • Entry point to BGS-geoIDS for most users • Tells potential users what is available and other key details • National Geospatial Data Framework (NGDF) Discovery Metadata Standards has 36 fields of which 13 are mandatory.
BGS-geoIDS • Compilation of Discovery Metadata • Data Model of Existing System • Data Policy and Management • Desktop Data Delivery
Data Model of Existing System • Reverse engineer a physical data model • Identify and implement missing links • Identify and migrate workstation database to corporate databases • Technical Metadata
BGS-geoIDS • Compilation of Discovery Metadata • Data Model of Existing System • Data Policy and Management • Desktop Data Delivery
Data Policy and Management • Development of a corporate data policy • Development of a corporate data management plan • Development of data management plans for individual projects

DGSM Vision The DGSM is a framework for managing BGS's knowledge of the UK and its surrounding continental shelf. It will foster a model-centred ethos with BGS in which all geoscience disciplines will contribute to and enhance the development of a set of multidimensional, coherent, integrated geoscience models.

DGSM Framework 1 • Enhance existing data model to deal with geometrical and topological relationships • Design a data warehouse to contain application specific datasets • Definitions of metadata necessary to identify standard geometric and Warehouse models • Defining and disseminating best practice
DGSM Framework 2 • Setting project software standards • DGSM policies covering procedures for model validation and approval, ensuring standards in model development and update • Developing the approaches to geoscience 'authoring' of documents and knowledge • User training programme
DGSM Trail Areas • Selected trail areas to test a variety of geological environments • London and the SE • Midland Valley of Scotland • Atlantic Margin of the UK Continental Shelf • Great Yarmouth • Cheshire Basin
