Frequently Asked Questions
- The search isn't finding the map I expect
- The system uses Google Maps to establish the co-ordinates of the location searched for. Where multiple locations exist, the most common is generally chosen. For example searching "St Ives" leads to the Penzance map sheet rather than St Ives, Cambridgeshire. However if desired, the Huntingdon map can be found by simply appending the county and searching for "St Ives, Cambridgeshire".
- Why are some maps old and some new?
- The BGS mapped and have remapped different parts of the country at different times (details of the mapping can often be found by clicking "Map Record" for a particular map). Some locations have many maps dating across the last 200 years whereas some have very few. In all cases this service links to the most recent map scan available for each location.
- Why is there a gap in mid-Wales?
- The Knighton sheet in mid-Wales was only very recently completed and is not currently available to the public.
- I've found a bug or inaccurate data, who do I tell?
- We endeavour to ensure that this service provides a useful and accurate catalogue of geological map scans but it is possible that the odd gremlin will have snuck in. Please contact us and we will get it fixed as soon as possible.
