Computer-assisted teaching of geological map interpretation to undergraduate civil engineers

Undergraduate civil engineers frequently find it difficult to learn to interpret geological maps by traditional methods. These difficulties arise as the result of a failure to link visual cues on the map with a correct perception of the corresponding three-dimensional structure. This Paper describes a computer-based approach in which the student is presented with a three-dimensional (3D) model of the structure, which may be viewed in plan, section or 3D as required. This model is closely linked to operations on the paper map which it enhances rather than supplants. It has been found by most students that use of the computer model allows them to develop a better appreciation of the subsurface structure from the map, by giving assistance with the recognition and interpretation of the appropriate visual cues.
