Ko, K. and Lee, H.-J., 2019. Detecting geological structures in coastal areas with unmanned aerial vehicle photogrammetric surveys. In: Jung, H.-S.; Lee, S.; Ryu, J.-H., and Cui, T.

This study attempted to use unmanned aerial vehicle (UAV) photogrammetry for structural mapping at limited exposure outcrops in the west coast area of southwestern Korea. The west coast area of the Korean Peninsula has a large tidal range, and there are restrictions for traditional structure mapping. A study site was selected, and high spatial resolution images (< 5 cm per pixel) were obtained at low tide. The UAV survey identified 50 brittle structures (fractures and faults that were divided into three groups) and changes in the bedding trace. The bedding trace demonstrates various directional verging of the fold geometry that indicates slump-fault structures. While more research is still necessary, this study demonstrated that UAV mapping techniques are very useful for geological structural analysis in coastal areas.
