Three-dimensional (3D) geological models are important representations of the results of regional geological surveys. However, the process of constructing 3D geological models from two-dimensional (2D) geological elements remains difficult and is not necessarily robust. This paper proposes a method of migrating from 2D elements to 3D models. First, the geological interfaces were constructed usi...

A major geological GIS project: the 1:5 Million International Geological Map of Europe and Adjacent Areas (IGME 5000) is being managed and implemented by the Federal Institute for Geosciences and Natural Resources (BGR). The aims of the project are to develop for the whole of Europe a GIS underpinned by a geological database, a printed map depicting up-to-date and consistent geological informat...

As a provider of geological advice to industry, academia and the public, the British Geological Survey (BGS) has recognised the need to change the way it presents geoscientific information, resulting in the construction of attributed 3D geological models. The need to deliver 3D modelling solutions is of great importance in urban areas, where geological factors play a major role in supporting gr...
