Data search
BGS is a data-rich organisation with over 400 datasets in its care.
Datasets
Hydrogeology 625K
The hydrogeological map indicates aquifer potential in generalised terms using a threefold division of geological formations.
BGS Geology
The Digital Geological Map of Great Britain (DiGMapGB) project has made digital geological map data available for much of Great Britain. It ranges from national (small-scale) to detailed (large-scale) resolutions with the availability of the five geological themes.
BGS GeoSure
The BGS GeoSure datasets identify areas of potential hazard and, therefore, potential natural ground movement, in Great Britain.
Borehole Index
The Single Onshore Boreholes Index has over one million records of boreholes, shafts and wells from all forms of drilling and site investigation work.
Map Viewers
Geology of Britain viewer
The Geology of Britain viewer is a simple tool aimed at the general public that helps you explore the geology around where you live.
GeoIndex (Offshore)
The offshore GeoIndex shows the range of marine geoscience data held by the BGS within the National Geoscience Data Centre (NGDC).
Information Hub
Photomicrograph gallery of species of Reduviasporonites Wilson, 1962 a joint initiative with Geoscience Australia
A forum to illustrate fossil specimens held in the collections of the British Geological Survey (BGS).
Vocabularies web service
The vocabulary service has been implemented as a RESTful web service delivering lists of standardised terms covering a range of geoscience topics.
Vocabularies
BGS geoscience vocabularies provide consistency in our classification systems by controlling the spelling and terms used in our data holdings.
Library online card catalogue:UDC
The card catalogue records items added to the BGS Library service from 1970 to the mid 1980s, when the computerised catalogue ENVIROLIB began
Technologies
Coordinate converter
Convert British National Grid to latitude and longitude (WGS84) via online form, web service or bulk conversion.
Sensor data
Real-time monitoring of environmental phenomena is a large and growing area of interest in BGS and wider research communities.
GeoIndex WMS services
GeoIndex datasets are made available as Open Geospatial Consortium (OGC) Web Map Services (WMS). View in compatible software or in portal-style websites that use a map-based interface to connect to WMS services.
Mobile apps
Bespoke mobile apps, such as iGeology and mySoil that allow you to view BGS datasets on a map where ever you are.
