1. General Description of Data to be Managed

1.1. Name of the Data, data collection Project, or data-producing Program:
Structure from Motion (SfM) Coral Vital Rates Annotations derived from Fixed Site Imagery across the Hawaiian Archipelago from 2014-2019
1.2. Summary description of the data:

The data described here are coral planar area measurements derived from the GIS analysis of benthic photomosaic imagery. The source imagery was collected using a Structure from Motion (SfM) approach during in-water surveys conducted by divers. All sites were surveyed at least twice and image collection intervals ranged from a few minutes (for error estimation) to 1-3 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 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. The photographs were processed using Agisoft Metashape and Viscore, a custom visualization software, to generate 3D dense point clouds (DPCs) and 2D orthorectified images (orthoprojections). Orthoprojections were uploaded to ArcGIS where corals were annotated and tracked over time to measure changes in vital rates (e.g. recruitment, mortality, growth).

In total, this dataset 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.

5.1. Processing workflow of the data from collection or acquisition to making it publicly accessible
(describe or provide URL of description):

Lineage Statement:
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 using Viscore software. Next, the orthoprojections were imported into ArcMap 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 vital rates change in coral planar area of each coral colony was tracked by linking annotations of the same live coral across each time point. Data was exported from ArcMap and all statistics and figures were performed in R.

Process Steps:

  • 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. Sites were imaged either in a gridded pattern as the diver swam 1.5 m off the seafloor, or in a circular pattern where the diver swam 1 m off the seafloor. In both cases, divers collected enough photographs to produce 60%-80% image overlap and completed two full passes of the site.

U.S. Dept. of Commerce, NOAA Technical Memorandum NOAA-TM-NMFS-PIFSC-120, https://doi.org/10.25923/a9se-k649)
  • 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 and aligned separately in Agisoft Metashape (AgiSoft Metashape Professional Version 1.6.1) and used to build 3D dense point clouds (DPCs) following parameters described by Suka et al. (2019). The 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, as well as a corresponding scale grid, were exported from Viscore.

Measuring Coral Vital Rates Using Structure-from-Motion Photogrammetry at Fixed Sites: Standard Operating Procedures and Error Estimates.

  • Orthoprojections of all time points from the same permanent site were uploaded to ArcMap for imagery annotation and scaled using the scale grid exported from Viscore. 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 2.5m2 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 was 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 with the Viscore Image View feature 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 until a higher sample size could be reached. Coral ID (to lowest taxonomic level), planar area, perimeter length, and a unique identifying number for each annotated coral were recorded in the ArcMap attribute table. The unique identifying numbers were used to track the fate of each coral colony. Corals identified within multiple time points were linked together using their unique identifying number within the ArcMap attribute table.

U.S. Dept. of Commerce, NOAA Technical Memorandum NOAA-TM-NMFS-PIFSC-120, https://doi.org/10.25923/a9se-k649)
  • Annotations created in ArcMap 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. Absolute change in coral patch area (cm2) and percentage change in coral patch area (delta cm2/initial cm2) were calculated in R. Additionally, outliers falling three standard deviations beyond a metric’s mean (area change, percent area change) were marked and removed from calculation of means and error bounds.
