Since its inception in 1835, the British Geological Survey (BGS) has been responsible for providing much of the earth science related information that is required by government, the public and institutions. These requirements have evolved over time, with emphasis shifting between information on coal, water supply, radioactive waste disposal, radon potential, aggregate resources, mineral resources, geotechnical information and planning information and many others (Culshaw, 2005). In order to satisfy its commitment to provide expertise and advice on the extent and severity of 

natural geohazards throughout the country, the BGS has built and currently maintains over 200 national strategic datasets. Providing information that helps to manage the impacts of geological hazards and climate change are now very important drivers for BGS. Indeed, BGS’ parent body, the National Environmental Research Council (NERC) regards Natural Hazards and Environmental Change as two of the principal areas of research funding. This paper describes how one of those datasets is currently being developed, and how important GIS and digital capture technology has been to this process.
