 This study tested the use of structure for motion, SFM, to create a high-resolution digital surface model, DSM, of a beach-dune system using unmanned aerial vehicles, UAVs. The results showed that the SFM approach was successful in producing a DSM with similar accuracy to a terrestrial laser scan, TLS, which is typically considered the gold standard for creating DSMs. Additionally, the SFM approach was found to have a lower cost than TLS, making it a viable option for creating DSMs. This article was authored by Francesco Mancini, Marco Dabbini, Mario Gatelli, and others.
