After 170 years of producing 2D maps, the British Geological Survey is beginning to produce systematic 3D geological models. This paradigm shift finally enables the full capture and transfer of geological knowledge that until now has been unavailable to decision makers and society as a whole.

These standard models are termed LithoFrames and are being assembled at several resolutions for specific users needs, in line with our past map series. Many of the detailed 3D models are built using GSI3D, a software and methodology that mimics the traditional working practices of Geologists: the need to apply geological theory, and the ability to work with unevenly distributed and heterogeneous data. The established methodology enables continuous geological revision with a fully dynamic approach.

In order to derive maximum benefit from these models, they have to be disseminated to clients and public, ideally without having to revert to paper, GIS or other external software applications. Images, captured video animations and value-added data are still delivered using proprietary platforms as many of our clients are comfortable with these delivery mechanisms. However, these options have two major shortcomings …. they can not convey the full richness of an attributed model, and they don't allow analysis or visualisation in 3D.

BGS and INSIGHT GmbH have collaborated to produce unique model delivery software to fill this gap. The LithoFrame Viewer performs analysis of models through predictive boreholes, uncovered geological maps, synthetic vertical and horizontal sections and exploded views of the geology. The model can also be switched between geological attributes such as lithology, permeability or compressibility. Embedding models within this software enables their easy delivery through digital media, therefore creating a real 3D geological map.

In order to further appreciate the geology within the landscape it is also possible to view these models in conjunction with terrain models and aerial photographs within immersive 3D stereo visualization facilities using GeoVisionary, a revolutionary new software system developed by BGS and Virtalis Ltd.

The main beneficiaries of all these developments will be the general public and science students as Geology can now be presented and studied as what it really is – a true 3D system.
