If you're on LinkedIn you may be interested in joining the group Open 3D Geological Modelling Community.

Whilst this group is not specific to Europe it is a useful forum for discussion and is maintained by the same people who operate this website.

The European 3D Geological Modelling Community is organized by the following people.

Holger Kessler, British Geological Survey

Geologist & Team Leader Modelling Systems

Holger Kessler joined the BGS in 1998 with a degree in Physical Geography and Soil Science from the University of Frankfurt in Germany. For the beginning of his career he was employed as a geological surveyor mapping glacial deposits and landscapes in North Norfolk and Yorkshire. In the early 2000s Holger became involved with a major research project at the BGS developing the capabilities for 3 dimensional geological modelling.

Since then Holger has been instrumental in moving the BGS from a traditional mapping to a modern digital modelling organisation, working closely with stakeholders such as the Environment Agency and the geotechnical engineering sector. His main ambition is to make all BGS data and information as useful and accessible as possible to end users and policy makers in order to make more science-based decisions about the subsurface.

Gerold Diepolder, Bavarian Environment Agency (LfU)

Gerold W. Diepolder studied geology at the University of Munich. After earning his PhD in 1990 with a thesis on the Bushveld Complex in South Africa he joined the Bavarian Geological Survey (now: Bavarian Environment Agency, LfU) as a research associate with remits on hydrogeology and the geopotentials of the deep subsurface. Short-term overseas assignment for the Federal Institute for Geosciences and Natural Resources (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) in Namibia in 2001.

For 8 years until September 2016 Gerold was head of the 3D study group of the German State Geological Surveys (Staatliche Geologische Dienste), lately realigned, now being chief executive of the task force “metadata for 3D geological models”. Gerold also was the initiator, coordinator and head of the 2012–2015 transnational 3D modelling and geopotential assessment project GeoMol and is now engaged in several European projects and initiatives geared towards interoperability and web-based dissemination of 3D geological models.
