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)

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.

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.
