Structure-from-motion photogrammetry of Antarctic polychaete reefs
This repository contains all the programming scripts and notebooks to process the orthomosaic and digital elevation raster files (.tiff) to retrieve benthic structural complexity metrics.
Encouragement to use, clone and cite the repository presented here. Scripts are presented in both R and Python, notebooks are presented in Python.
This is a repository corresponding to the publication:
Montes-Herrera, J.C., Hill, N., Cummings, V.J., Johnstone, G., Stark, J.S., Lucieer, V. 2023. Remote sensing of Antarctic polychaete reefs: Reproducible workflows for quantifying benthic structural complexity with action cameras, remotely operated vehicles, and structure-from-motion photogrammetry. Remote Sensing in Ecology and Conservation, 10: 72-90. https://doi.org/10.1002/rse2.358
Data availability
Orthomosaics and Digital Elevation Models available as raster files (.tiff) https://doi.org/10.5281/zenodo.7115132
Imagery was collected with a GoPro 5 at 2 Hz mounted on a remotely-operated vehicle in Ellis Fjord, Antarctica by the Australian Antarctic Division in 2019. Orthomosaics and concomitant digital elevation rasters were created in Metashape. A laser-scale of 10 cm was used.
Respectively, benthic biodiversity and structural complexity metrics were retrieved from the orthomosaic and its concomitant digital elevation raster ('3D model').
