WinGeol's FaultTrace is a software tool assisting in semi-automatic structural geological mapping of faults and bedding planes. Digital elevation models - such as, for instance, SRTM or ALOS data - are used in combination with satellite imagery for a first structural geological assessment without the requirement of being at the site. Therefore, it is well suited for inaccessible terrain. Borehole data, geological and seismic profiles can be displayed to support the mapping process. Plane elements can be assigned to single as well as to more complex composite geological structures. Moreover, previously mapped data can be densified by interpolation, which is useful to enhance the mapping quality. The tool aims to provide a virtual environment allowing for fast-track and optimized data generation for 3D geological models. The functionality of FaultTrace is demonstrated in two different case studies: The Richãt Structure in Mauritania shows relatively planar fault structures within low-relief topography; the Vineh Structure in Iran shows a complex folding in high mountainous terrain. The studies discuss which structural geological settings let expect a satisfying performance of FaultTrace, and what factors limit the achievement of meaningful results. For the most part, the findings are independent of FaultTrace and, thus, valid for similar software tools.
