Abstract

Scarelli, F.M.; Cantelli, L.; Barboza, E.G.; Rosa, M.L.C.C.; and Gabbianelli, G., 2016. Natural and Anthropogenic coastal system comparison using DSM from a low cost UAV survey (Capão Novo, RS/Brazil). In: Vila-Concejo, A.; Bruce, E.; Kennedy, D.M., and McCarroll, R.J. (eds.), Proceedings of the 14th International Coastal Symposium (Sydney, Australia). Journal of Coastal Research, Special Issue, No. 75, pp. 1232 - 1236, ISSN 0749-0208.

In many cases, unplanned urbanization is the main factor that causes a decrease in coastal resilience. This paper compares the differences between the anthropogenic and natural coastal zone, based on the morphological dune reconstruction, using a low cost UAV (unmanned aerial vehicle) survey and the photogrammetric reconstruction method. The study area is in the Northern Littoral of Rio Grande do Sul State, where the dunes have few man-changes and are adjacent to an anthropogenic zone with a highly modified beach/dune system. By photogrammetric reconstruction it was possible to obtain a high-resolution DSM (Digital Surface Model) and a high-resolution othophoto to analyse differences in morphology. Data acquired by UAV's are important to coastal managers and decision makers as they can collect high-resolution data and be used for Integrated Coastal Zone Management. Moreover this work propose a low cost method for obtaining a high-resolution data for researchers and local authorities.
