EDINA has updated Geology Roam with a whole range of new data, allowing users access to nearly all the data available from Geology Download without needing to put it into GIS software. We have also updated the Active legend, so you can now order it by the Age of the Rocks on the map.
New Data
As you can see in the image above the most zoomed out levels now have the Offshore Geology data (DigRock250 and DigSBS250) allowing you to see the rocks and sea bed sediments around the coast of the United kingdom. We have also added in the most detailed onshore geological mapping from the British Geological Survey, the 1:10,000 and 1:25,000 scale maps (DiGMapGB-10 and DiGMapGB25). Please note that these datasets do not have national coverage, where they are not present there is a water mark on the map to inform you. As there is almost no overlap between these two large scale datasets EDINA has combined them into a single detailed geology layer.
Basemaps
To allow different datasets to be viewed at the same scale we have introduced the basemaps tab so that the geology data can be switched with the scale remaining the same. Adding the basemaps tab has also allowed us to introduce new ways of viewing the same data, with all the geology layers now viewable as both the Rock Unit e.g. Kimmeridge Clay Formation and Rock Type e.g. Mudstone.
The basemaps tab has allowed many datasets to be view at the same scale so in addition to the new geological data we have also added several extra types of data which provide information about the soil and hydrogeology of Great Britain. The Geological Indicators of Flooding; Permeability (Max and Min); 1:625,000 Scale Hydrogeology; along with Soil Strength, Texture and Calcium Carbonate content from the Soil Parent Material Data are now all available as basemaps.
Active Legend

The final change made to the Geology Roam interface has been to the Active Legends which now allow you to order the entries by their age. The ordering is based on the MAX_INDEX attribute in the geology data that allows you to order the Rock Units based on its oldest age.
The active legend still lets you rocks on the map by clicking on the legend and vice versa.
A full list of the products available in each view / scale can be found in the Geology Roam “How To Guide” here:
