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.

Superb app

If you're interested in knowing the structure of the land in which you are spending some time away from home, then this is the app to get. Put together by the top experts in the UK, it gives you all the information you could want, right from the very spot where you're standing to everything you can see around you.
Get it use it, enjoy it!

So useful

Such a useful app. I can walk around the landscape, see the geological map at the same time, checking where I am with the GPS feature, and find out what the rocks are. If I find an unusual outcrop, the map immediately shows me what I'm looking at.
This new version has improved how the GPS works, making it quicker and easier to use.

Great geology

I'm a Chartered Structural Engineer and I've been using this app for years. It's great for giving you an initial look at the ground conditions. It provides the same info as on the geological drift sheets that I've bought in times gone by.

Please don't think this app will replace a ground investigation. Drilling a bore and testing will give far better results.
