Reports of ground investigations (also known as site investigations) produced by external organisations carried out for all forms of site investigation. The reports date back to the 1950s and may contain information on boreholes, trial pits, laboratory tests and chemical analyses etc. The collection covers the whole of Great Britain with concentrations around urban areas and transportation routes. The interpretive parts of the reports are not available to public. Reports from onshore Great Britain (or near shore) site investigations are held in the National Geoscience Data Centre in paper, microfilm or digital format. The entire collections at BGS Edinburgh has been scanned, but in BGS Keyworth currently only reports received since 2002 have been scanned. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection. Images are stored in TIFF format and are indexed in the Site Investigation Database and Detailed Accessions Database. The boreholes within the report, and any associated images, are linked to the Single Onshore Borehole Index.
