3D models help us visualise the ground beneath our feet without
the need for training in complex geological techniques.
Modelling the Earth's subsurface can help us understand the
relationship between geology and our environment. The BGS is
developing a national geological model of the UK's subsurface to
give decision makers greater clarity in planning for the future.
Our traditional printed, 2D geological maps show the
distribution of geological units at the surface, but 3D models
of the same geology shows us the depth of features such as
faults, changes in thickness, tilted units and subsurface
contacts. 3D models can: We have developed a set of online tools
to enable the user to interrogate the subsurface geology; drill
a virtual borehole or draw a virtual cross-section or horizontal
section using Groundhog through one of our five example models.
We are in the process of producing a national 3D model of the
subsurface. Work is underway to develop a model viewable at a
range of scales representing the rocks
