Dune metrics for ecological restoration sites along the north coast of Puerto Rico. These sites are being restored using the following methods: installation of wooden boardwalks, planting stabilizing vegetation, biomimicry matrices for promoting the accumulation of sand and signage. The metrics are calculated from imagery captured with an RTK GPS enabled DJI Phantom 4 Pro and Pix4D photogrammetry software. Missions are flown before project, after the initial restoration measures are implemented and every year after that for monitoring and adaptive maintenance purposes.
