1 Data, Information and Knowledge in the British Geological Survey Jeremy Giles

2 Data Rich n 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.

3 A Bit of History n BGS has been collecting for 164 years n Oldest records predate BGS n Manual index systems have served for the bulk of that period n Digital systems developed from the bottom up to meet the needs of specific projects n Need to bring control recognised in mid-90s

4 Data Management n Two projects have been initiated to improve situation – Geoscience Integrated Database System (BGS-geoIDS) – Digital Geoscience Spatial Model (DGSM)

5 Time Table BGS-geoIDS DGSM

6 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.

7 BGS-geoIDS n Compilation of Discovery Metadata n Data Model of Existing System n Data Policy and Management n Desktop Data Delivery

8 Compilation of Discovery Metadata n Entry point to BGS-geoIDS for most users n Tells potential users what is available and other key details n National Geospatial Data Framework (NGDF) Discovery Metadata Standards has 36 fields of which 13 are mandatory.

21 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.

23 DGSM Framework 1 n Enhance existing data model to deal with geometrical and topological relationships n Design a data warehouse to contain application specific datasets n Definitions of metadata necessary to identify standard geometric and Warehouse models n Defining and disseminating best practice

24 DGSM Framework 2 n Setting project software standards n DGSM policies covering procedures for model validation and approval, ensuring standards in model development and update n Developing the approaches to geoscience 'authoring' of documents and knowledge n User training programme

25 DGSM Trail Areas n 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
