GeoIndex (onshore)

BGS GeoIndex is a web tool for professional users who need to access BGS data as part of their business requirements. The map viewer is free to use and is designed to work on desktop and mobile devices.

Users can search BGS datasets and navigate the map-based index which holds a wealth of information that we have collected or have obtained from other sources.
