Abstract
[EN] This contribution discusses the potential of UAV-assisted (unmanned aerial vehicles)
photogrammetry for the study and preservation of mining heritage sites using the example of Roman
gold mining infrastructure in northwestern Spain. The study area represents the largest gold area in
Roman times and comprises 7 mining elements of interest that characterize the most representative
examples of such ancient works. UAV technology provides a non-invasive procedure valuable for the
acquisition of digital information in remote, difficult to access areas or under the risk of destruction.
The proposed approach is a cost-effective, robust and rapid method for image processing in remote
areas were no traditional surveying technologies are available. It is based on a combination of data
provided by aerial orthoimage and LiDAR (Light Detection and Ranging) to improve the accuracy
of UAV derived data. The results provide high-resolution orthomosaic, DEMs and 3D textured
models that aim for the documentation of ancient mining scenarios, providing high-resolution digital
information that improves the identification, description and interpretation of mining elements such
as the hydraulic infrastructure, the presence of open-cast mines which exemplifies the different
exploitation methods, and settlements. However, beyond the scientific and technical information
provided by the data, the 3D documentation of ancient mining scenarios is a powerful tool for an
effective and wider public diffusion ensuring the visualization, preservation and awareness over the
importance and conservation of world mining heritage sites.
