iGeology - Interactive geological mapping of the UK.

iGeology is for anyone who wants to explore their local geology, at street-level scale, virtually anywhere in the UK.

Amateur geologists, walkers and gardeners can look at what’s in their local area, to find out about the rocks at the surface (superficial deposits) or the bedrock beneath.

Search on place names or the postcode where you live, then click on the map and reveal the rocks beneath your feet. iGeology will locate your iPhone or iPad (if GPS is enabled) and zoom to your location.

The maps use the British Geological Survey’s national scale (1:625 000) and ‘Landranger’ scale (1:50 000) geological datasets of the United Kingdom (UK).

Map coverage
5% of 1:50000 scale data is unavailable for England, Scotland and Wales.
Only 1:625 000 scale data is available for Northern Ireland.

live in the Netherlands now and NO rocks! can't forget the the rocks in the UK, lovely app, dear NERC and BGSthank you!

Noticed a small mistake in my review, indeed there are nor rocks where I am and still love the UK geology ! Still a TOP App and a great Thank you to the BGS and NERC!

Nice map, no information


It is not very clear we're this app is meant for: it displays a nice geological map with very good zoom possibility, but there is no way to find out what the colours on the map mean. I could find no legend with the map, and when you click on a point in the map it always says there is no information available. Strange, is this a bug or does it mean I have to buy something ?
