This dataset contains benthic data from generated from imagery collected by divers conducting photogrammetric monitoring at EcoRRAP sites (see SOP #14: Reef monitoring sampling methods | AIMS). These images used are the underlying images of the EcoRRAP 3D models and are used here to assess benthic community composition within EcoRRAP plots. A subset of images were extracted for this dataset by using a python script that filtered for image position within 3D models, to enable the best spatial stratification, as well as for aspect to maximise extraction of images facing the benthos. A 1000-pixel bounding box was applied to the edges of the image to remove areas of distortion (original image size was 8256x5504 pixels). Images were extracted for 352 plots in 2021, 336 plots in 2022, 327 plots in 2023, and 192 plots in 2024 due to field imaging constraints. Note that the 2024 data is only from reefs in the EcoRRAP Central Cluster and the Torres Strait Cluster. Forty-two images per plot with 50 points per image were analysed in ReefCloud, providing approximately 100% cover of each plot. Images from a subset of plots were manually annotated in ReefCloud to train an automated image analysis model and the remaining plots were analysed using the automated model. Images were annotated using the EcoRRAP Community Composition Label Set. The ReefCloud ML model was trained with a goal of achieving 80% accuracy for identification of benthos. Training proceeded as an iterative process with model diagnostics assessed after each round of training. Once performance targets were reached across course taxonomic classes, targeted annotation was undertaken to improve the model performance for specific classes. See summary stats document associated with this record for preliminary summary statistics for benthic cover in EcoRRAP sites.
