Overview

Digital Outcrop Models (DOMs) are precise 3D digital representations of rock outcrops, typically constructed using imagery captured by cameras or other sensor types. These sensors can be ground-based or mounted on Unmanned Aerial Vehicles (UAVs), commonly known as drones. The resulting georeferenced 3D models can be digitally interpreted and seamlessly integrated with other geospatial data for a diverse array of applications. These applications include but are not limited to, the development of virtual geological field trips for educational purposes in the field of geoscience.

The morning of the workshop would include presentations on topics related to data acquisition methods, data processing techniques, visualisation strategies, digital interpretation protocols, integration with other data types, and illustrative case histories. The afternoon would be a hands-on digital outcrop modelling course.

Participant profile

The ideal audience for this workshop would comprise:

Subsurface modellers in energy and environmental sectors:  geoscientists and engineers who are focused on constraining subsurface static/geological models for petroleum, hydrogen, and geothermal reservoirs, stratigraphic units for carbon dioxide sequestration, and aquifers. These professionals recognise the utility of outcrops in bridging the scale gap between seismic reflection profiles and well data, thereby providing critical insights into geological features that are not visible in typical subsurface datasets.

Geoscientists with a specialisation in stratigraphy and structural geology, who seek to study outcrops including those portions that pose accessibility and safety challenges, such as high cliffs. Utilising georeferenced DOMs, these geoscientists can make quantitative measurements—such as the orientation of strata, faults, and joints— from otherwise inaccessible areas, increasing the size and statistical significance of quantitative field datasets.

Geoscientists that employ DOMs as a preparatory tool for optimising fieldwork plans. By utilising digital models, fieldworkers can prioritise key areas for on-the-ground investigations, thereby maximising the focus and efficiency of field visits.

Preservationists and archivists: geoscientists interested in the digital preservation of significant outcrops for future examination and analysis. This is particularly pertinent for outcrops exposed during infrastructural developments like road and highway construction, which, especially in humid regions, are susceptible to rapid overgrowth of vegetation that obscures geological features.

Educators and students: Geoscientists who aim to develop virtual geological field trips to classic outcrop areas globally. These digital excursions serve as analogues for understanding subsurface geology and eliminate the financial and safety-related constraints associated with physical field visits.
