Rodriguez C, Amir C, Gray A, Asbury M, Suka R, Lamirand M, Couch C, Oliver T. 2021. Measuring Coral Vital Rates Using Structure-from-Motion Photogrammetry at Fixed Sites: Standard Operating Procedures and Error Estimates. U.S. Dept. of Commerce, NOAA Technical Memorandum NOAA-TM-NMFS-PIFSC-120, https://doi.org/10.25923/a9se-k649
The data described here are coral planar area measurements derived from the analysis of benthic photomosaic imagery collected at fixed sites across Pacific Island regions since 2014. The source imagery was collected using a Structure from Motion (SfM) approach during in-water surveys conducted by divers. Imagery archival is documented separately here: https://www.fisheries.noaa.gov/inport/item/63091. All sites were surveyed at least twice and image collection intervals ranged from a few minutes (for error estimation) to 5 years apart. In situ surveys, post-processing, and analysis were funded by NOAA Coral Reef Conservation Program (CRCP) and Ocean Acidification Program (OAP). Data collection was conducted by the NOAA Fisheries, Ecosystem Sciences Division (ESD).
Survey sites consisted of sites previously established by collaborators from Scripps Institution of Oceanography, starting as far back as 2014, and new sites established in 2019 by NOAA ESD. During each survey, physical markings which identify each permanent survey site were either established or found using GPS coordinates previously collected. During image collection, the diver swam at a constant distance from the bottom of the reef while continuously capturing overlapping photographs, capturing approximately 100 m2 of reef habitat. 3D dense point clouds (DPCs) and 2D orthorectified images (orthoprojections) derived from these photographs were used to to measure changes in coral vital rates (e.g. recruitment, mortality, growth) over time.
Due to the labor-intensive and time-consuming nature of coral annotation, we used a randomized sub-sampling strategy that provided enough colony-level data across a wide range of size classes to fit robust demographic models. Each site was sub-sampled by randomly distributing a minimum of 10 0.5 m2 quadrats throughout each orthoprojection. All corals whose centroid fell within the quadrat were annotated until a sufficient number of corals were annotated (n >/=30 for each target coral species). The target taxa species consisted of two genera - Pocillopora and Porites.
In total, this dataset currently includes planar area and associated vital rates measurements for 5 coral species in 2 genera (Pocillopora and Porites) at 14 sites throughout the Hawaiian Archipelago and 3 genera (Pocillopora, Porites and Acropora) at 10 sites throughout the Mariana Archipelago.
The purpose of the SfM surveys of permanent sites throughout the U.S. Pacific is to track coral vital rates (e.g. growth, mortality, recruitment) and how they vary across taxon, regions, and environmental gradients. This study leverages SfM, an emerging photogrammetry technique, to allow efficient data collection alongside NCRMP essential efforts.

dataset
Representativeness
The data set derived from the imagery is only as good as the images and image-derived products. All coral patches were delineated high resolution orthoprojections and raw imagery was referenced when determining patch perimeters.
Accuracy
Survey sites were aligned atop one another to ensure coral patches could be followed through time and to ensure delineates were collected using the same orthorectified view which improves accuracy of planar area change measurements.
Coral species identification and size data were extracted by SfM image annotators that had been trained and tested on coral taxon identification and morphology. All annotators met a set of minimum standards for coral data collection.
Field Precision
The average Ground Sample Distance (GSD, resolution/pixel) for the produced 3D Structure from Motion models was 0.21 cm/pix, allowing confident identification of coral species from the resulting high-resolution 2D orthoprojections.
Completeness Report
SfM imagery was collected at 14 sites throughout the Hawaiian Archipelago across time intervals from several hours to 3 years. For the Mariana archipelago, imagery was collected at 10 sites at 3 and 5 year time intervals. All sites were between 9-16m deep and and cover approximately 100 m2 of reef. Due to the labor-intensive and time-consuming nature of coral annotation, we used a randomized sub-sampling strategy that provided enough colony-level data across a wide range of size classes to fit robust demographic models. Each site was sub-sampled by randomly distributing a minimum of 10 0.5 m2 quadrats throughout each orthoprojection. All corals whose centroid fell within the quadrat were annotated until a sufficient number of corals were annotated. The target taxa across both archipelagos consists of three genera - Pocillopora, Porites and Acropora. Prior to analysis, coral colonies <19 cm2 were removed from the dataset. In the Hawaiian archipelago dataset, all coral colonies that experienced full mortality in the final time point or were only observed in the final time point are not included in this dataset.
Conceptual Consistency
The same method of annotation was used for all SfM imagery.
Benthic imagery was collected at permanent sites and generated into 3D dense point clouds (DPCs) using Agisoft Metashape software. DPCs from the same site, but different collection dates were converted into 2D orthoprojections and scaled, oriented and aligned together. Next, the orthoprojections were exported for annotation. Orthoprojections were sub-sampled by randomly distributing quadrats throughout the orthoprojection. Quadrat location was conserved across all orthoprojections associated with the same permanent site. Target coral species were identified within each quadrat and their perimeters were annotated until a sufficient sample size of each species was recorded. The changes in coral planar area of each coral colony was tracked by linking annotations of the same live coral across each time point. All statistics and figures were performed in R.
Prior to image collection, each site was set up by placing at least two scale bars of known length, with ground control points (GCPs) at the end of each bar, 2-3 m away from the center of the survey area. At many sites, rebar caps with GCPs were also placed on the reference pins (36 in tall stainless steel rods used to mark the site). During plot set up, one diver drew a diagram of the plot, marking the location of each scale bar, reference pin, and distinctive benthic features. The depth and identification numbers of each scale bar were recorded in the diagram as well.
Divers swam ~1m off the seafloor, collecting enough photographs to produce 60%-80% image overlap and complete two full passes of the site.
Images for each site were evaluated for image quality and images deemed unsatisfactory (e.g. overexposed, images of blue water or images of divers, or images not taken perpendicular to the reef) were removed from the image set. Following image quality control, each set of raw images were imported, aligned separately in Agisoft Metashape and used to build 3D dense point clouds (DPCs) following parameters described by Suka et al. (2019). For the Hawaiian Archipelago dataset, DPCs were then imported into Viscore, a custom visualization software (Petrovic et al., 2014), where all DPCs from the same site, but from different time points, were scaled, oriented and aligned together using the GCP information. Each DPC was converted into a 2D orthorectified image (orthoprojection) and an identical top-down view of all othoprojections of the same site but different time points were exported from Viscore. For the Mariana Archipelago dataset, all scaling, orienting, alignment and 2D model creations were completed using Agisoft Metashape.

Due to the labor-intensive and time-consuming nature of annotation, we used a randomized sub-sampling strategy that provided enough colony-level data across a wide range of size classes to fit robust demographic models. To sub-sample each site, we selected the region where there was the most spatial overlap across all orthoprojections of the same site. Next, 10-30 0.5m2 quadrats were generated at random throughout the selected area and each labelled in numerical order.
Within the first 10 quadrats, all coral species on the target coral species list were annotated if their centroid fell within the quadrat. Corals were annotated by tracing the full perimeter of live coral tissue patches. During annotation, the original JPEG imagery was viewed alongside the orthoprojection to see fine scale colony details, observe colonies from multiple angles and locate colonies not visible in the orthoprojection (e.g. under ledges). If one or several coral species on the target list did not reach n = 30 live patches within the first 10 quadrats. These species were identified and annotated in additional quadrats, and sometimes outside the quadrats, until a higher sample size could be reached.
Unique identifying numbers were assigned to each patch of live coral tissue link coral patches across time and to track fission/fusion events.

Annotations were exported and quality controlled in R with specific queries to identify and correct data entry errors (e.g. misspelled species names, missing coral unique identifier, data in incorrect columns). Before analysis, all corals patches < 19 cm2 and corals that were not present in both the initial and final time point were removed from the dataset. For the Hawaiian archipelago dataset, absolute change in coral patch area (cm2) was calculated in R.

Source Contribution: This document builds upon Rodriguez et al. 2022 and provides detailed procedures for annotating imagery using both ArcGIS and TagLab software in tandem. These procedures are designed to efficiently generate coral rates data (e.g., growth, mortality, recruitment, fission, and fusion) within coral communities over time. While this standard operating procedure is designed to meet ESD needs, we use commercially available software, making these methods adaptable based on programmatic capacity and needs.

Source Contribution: This study utilized SfM 3D reconstruction software tools to create textured mesh models of a reef at French Frigate Shoals, an atoll in the Northwestern Hawaiian Islands. The reconstructed orthophoto and digital elevation model were then integrated with geospatial software in order to quantify metrics pertaining to 3D complexity. The resulting data provided high-resolution physical properties of coral colonies that were then combined with live cover to accurately characterize the reef as a living structure. The 3D reconstruction of reef structure and complexity can be integrated with other physiological and ecological parameters in future research to develop reliable ecosystem models and improve capacity to monitor changes in the health and function of coral reef ecosystems.

Source Contribution: The combination of 3D acquisition (terrestrial and airborne LiDAR, structured light, structure-from-motion) and 2D imaging (photographic, multispectral, panoramic, orthorectified, reflectance transformation) techniques allows the geometry, appearance and other aspects sites to be objectively documented. This study proposes a system for the direct visualization and analysis of such data, allowing the different aspects recorded to be layered together, and co-visualized with annotations and other relevant information. This study describes the required technical foundations, including gigapoint and gigapixel visualization pipelines that enable the dynamic layering of high-resolution imagery over massive minimally-processed LiDAR point clouds that serve as the base spatial layer. In particular, the study introduces the pointbuffer—a GPU-resident view-dependent point cache—as the foundation of our gigapoint pipeline, and outline the use of virtual texturing for draping of gigapixel imagery onto point clouds.
