Groundhog — virtual borehole, cross-section and horizontal section viewer

Groundhog 3D model viewer

Virtual borehole

Groundhog allows the user to drill virtual boreholes and slice through a geological model both vertically and horizontally using interactive tools on the fly.

This tool offers a glimpse into how geological models will be increasingly made accessible via the Web.

To demonstrate the type of information available, we have released models for five areas of the UK that reflect a range of geological settings.

Sample models available


The data obtained from the Groundhog viewer is based on a prediction and interpretation of the subsurface data. It should not be used as a replacement for a site investigation.

The depth of the lower geological unit in the model may be truncated at its base, such that the unit thickness is not accurately represented. The extent at which the geological succession is subdivided may vary between models.

Lithological information is generalised for each geological unit, and local conditions may vary.

For comprehensive information of the Geology at this point or line, please use the BGS GeoReport service.
