High-resolution scans of over 6,000 geology maps, previously published on paper, have been released on the internet by the British Geological Survey (BGS).
The BGS Maps Portal provides free-to-view small and medium scale maps produced by the BGS since geological mapping began in 1832 and includes the recent 1:50,000 mapping of England, Wales and Scotland, geochemical and geophysical maps and also historical maps.
The BGS said that traditionally, geological surveys focused on the geology maps of the solid subsurface and produced paper geological maps, but its strategy is now to continuously monitor geological processes and develop 3D digital geological models.
H2Ogeo uses geological maps as part of the desk based assessments it carries out for clients. Understanding the geology of an area is key to developing a quality conceptual site model and assessing the potential pathways and likely receptors from an impacted site.
