Abstract: The use of three-dimensional models represents an interesting approach to visualize, understand and analyze a geological environment. In Earth sciences, construction of 3D models and their use remain however not very widespread. That can be explained, in part, by the diversity of available data and the numerous steps required to build a valid and coherent 3D model. The purpose of this project is thus to propose a procedural guide that logically assembles 3D geological model construction steps while formally describing geometrical data (point, line, surface and volume) used. This formal description is based on ISO/TC211 geographic information standards to which an extension for the representation of the volumetric objects is added. The proposed guide facilitates the construction of 3D models by non-expert modellers. It was tested by non-experts who succeeded, in a proportion of 80%, in building 3D geological models which allows us to confirm the effectiveness and utility of the guide.
