Processing Coral Reef Imagery Using Structure-from-Motion Photogrammetry: Standard Operating Procedures (2023 Update) U.S. Dept. of Commerce, NOAA Technical Memorandum NOAA-TM-NMFS-PIFSC-159, 91 p. https://doi.org/10.25923/cydj-z260 The data described here result from benthic coral demographic surveys within belt transects of specified length and width for two life stages (juveniles and adults) across the US Pacific since 2013. This data is collected as part of the NOAA Pacific Islands Fisheries Science Center (PIFSC) and Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) led National Coral Reef Monitoring Program (NCRMP) missions around the Mariana Archipelago, American Samoa, Pacific Remote Island Areas, and the Hawaiian Archipelago since 2013. This metadata record replaces those previously separated by region (Catalog ID: 22790, 36164,36165,36166). The in-situ diver coral demographic surveys are part of the Rapid Ecological Assessment (REA) surveys for corals and fish conducted during ESD-led NCRMP missions. From 2013 to 2017, a two-stage stratified random sampling (StRS) design was used to survey the coral reef ecosystems across sub-island sectors and three depth strata (shallow: 0-6m, mid: 6-18m and deep: >18m). Starting in 2018 a one-stage StRS design was employed. These sites represent a broad range of depths (1-25 m), habitat types (aggregate reef, patch reef, pavement, rock and boulder and rubble), coral cover, and diving conditions. Allocation of sampling effort was proportional to strata area and variance in coral density. The StRS design effectively reduces estimate variance through stratification using environmental covariates and by sampling more sites rather than sampling more transects at a site. Therefore, site-level estimates and site to site comparisons should be used with caution. Starting in 2023 coral demographic data was also derived by the GIS analysis of benthic Structure from Motion (SfM) imagery. The source imagery was collected during in-water surveys conducted by divers, and is documented separately here: https://www.fisheries.noaa.gov/inport/item/63095.During each SfM survey, an 18m transect line was deployed along the isobath and photographed using underwater cameras while swimming in a back and forth swim pattern for later processing. At depths of 0-18m, SfM surveys were conducted over a 3 x 20m area and at depths >18m, a 3 x 13m area was surveyed, both with the transect running down the middle of the survey area. The photographs were processed using Agisoft Metashape software to generate orthomosaic images that were analyzed in ArcGIS for juvenile and adult coral colony demographic metrics. The data provide information on adult coral colony counts, morphology, size, partial mortality (old and recent dead), presence and causation of disease and other compromised health conditions, including bleaching. Juvenile colony surveys include morphology and size. Taxonomic identification of adult colonies is to the lowest taxonomic level possible and genus level for juveniles. Some segment observations were repeated for internal quality control starting in 2019, and indicated with a repeat segment flag and transectnum = -999; use column OG_OR_RPT_SEG to filter for only original segments. Refer to data dictionaries for details on column conditions. The raw data also include individual observations of crustose coralline algae diseases and Alcyonarian disease type and lesion size as well as the presence of other Anthozoans, such as other cnidarians including Alcyonareans, Zoantharians, Corallimorpharians, and Antipatharians (does not apply to PMNM surveys conducted in 2014 and 2015 or surveys conducted after 2017). The National Coral Reef Monitoring Program (NCRMP) details a long-term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP coordinates various Coral Reef Conservation Coral Reef Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis.

The NCRMP coordinates various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. NCRMP is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the CRCP and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), and many other partners. The PIFSC Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading biological monitoring in the U.S. Pacific Islands Region. The biological component of NCRMP in the Pacific provides a triennial ecological characterization at a broad spatial scale of general reef condition for reef fishes, corals and benthic habitat (i.e., fish species composition/density/size, benthic cover, and coral density/size/condition). Innovative analysis techniques are then used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time. false eng false Data View Data Table Adult Coral Belt Observations Data Dictionary 2024-10-22 publication Juvenile Coral Observations Data Dictionary 2024-10-22 publication reference_genus_spcode_datadictionary 2024-10-22 publication CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact WWW:LINK-1.0-http--link NCEI Contact Information Information for contacts at NCEI. information distributor https://accession.nodc.noaa.gov/0298217 WWW:LINK-1.0-http--link REFERENCE_GENUS_SPCODE.csv Lookup table for species and taxon codes used by the NOAA Fisheries Ecosystem Sciences Division across the US Pacific.

Accuracy This data should be assessed at the genus level due to variabilities in identifying at genus or species level. Observations were made by experienced benthic survey personnel who have been trained, undergone a series of calibration surveys and coral taxon identification testing, and have met a set of minimum standards for colony assessment and taxon identification in each region. The accuracy of species and genus level identification was high. The lowest taxonomic level of coral identification was genus except for a select number of species that were consistently identified to species by all divers conducting the surveys. The number of species may change for each survey year depending on the experience and training of the benthic divers. The list of coral species is included for each survey year. In other words, the individual records within each data set may include many more species than encompassed by the lists; however, these were not consistently identified across all surveys so these records should be assessed at the genus level. Prior to conducting surveys, the SfM image collector was trained to swim in a back-and-forth pattern to collect imagery with 60-80% overlap. Both classroom and field training were completed before any surveys were conducted. This training ensures that all SfM image collection was conducted consistently during the mission. Handheld GPS units were used to locate random sites and mark site locations. Analytical Accuracy The taxon code AAAA is included where the segment was surveyed and no individual colonies were found in both the juvenile and adult colony records. These are true zeros. The value -9 is a placeholder or missing value for the fields: colony length, colony width (juveniles), extent, and severity. 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 orthomosaics. Completeness Report Only sites from shallow water (0 to 30 meter depth range) hard-bottom habitats were annotated. At deep sites, bottom time is limited and therefore survey area is reduced from 3 x 20 m to 3 x 13 m. Therefore, shallower sites, 4 2.5 m2 segments were annotated and for deeper sites (>30 m) 3 2.5m2 segments were annotated along the central transect line. Within each 2.5 m2 segment, only 1m2 of the segment was sampled for juvenile demographic metrics and for all sites, regardless of depth, only the first three segments along the transect line were annotated. Conceptual Consistency Periodic examination of the data is conducted throughout each mission to check for diver bias or other discrepancies. While data are collected by divers and from SfM imagery, the same methods were applied to both survey types. Coral demographic data has been collected at stratified-random sites (StRS) across US Pacific Island Regions for the National Coral Reef Monitoring Program (NCRMP) since 2013. The methodology for selecting StRS and analyzing this data can be found in the sources listed below. The methodology has continued to evolve. Starting in 2023, some data was collected with GIS analysis alongside in-water diver surveys. The benthic SfM survey methodology, employed by the NOAA Ecosystem Sciences Division (ESD), began in 2019. Benthic imagery is collected at stratified random sites and generated into orthomosaic images using Agisoft Metashape software. Orthomosaics are imported into ArcGIS for annotation. Annotation of SfM belt orthomosaics is modelled after in situ diver adult and juvenile coral belt surveys employed by the PIFSC Ecosystem Sciences Division and includes coral species identification, maximum diameter measurement, partial mortality estimates, and disease and condition identification. A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems through the U.S. Pacific regions. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats. The stratification scheme included island, reef zone, and depth in all regions, as well as habitat structure type in the Main Hawaiian Islands. The habitat structure types included simple, complex, and coral-rich. Depth categories of shallow (0-6 m), mid (> 6-18m) and deep (>18-30 m) were also incorporated into the stratification scheme. Allocation of sampling effort was proportional to strata area and variance in coral density. Sites were randomly selected within each stratum. A geographic information system (GIS) and digital spatial databases of benthic habitats (NOAA National Centers for Coastal Ocean Science NCCOS), reef zones (IKONOS satellite imagery, NDGC 1998) bathymetry (NDGC 1998, CREP benthic mapping data), and marine reserve boundaries (NOAA) were used to facilitate spatial delineation of the sampling survey domain, strata, and sample units. Map resolution was such that the survey domain could be overlain by a grid using a GIS with individual cells of size 50 m by 50 m in area. A one-stage sampling scheme following Cochran (1977) was employed. Grid cells containing at least 10% hard-bottom reef habitats were designated as primary sample units (referred to as sites). Oliver, Thomas (808)725-5444 thomas.oliver@noaa.gov processor At each site, benthic Rapid Ecological Assessment (REA) surveys were conducted within one 10 sq. meter belt transect. Transects were 18 meters in length. Adult coral colonies (>=5 cm) were surveyed within four (1.0 x 2.5 m) segments at 5 meter increments along the 18 meter transect in the following manner: 0-2.5 m (segment 1); 5.0-7.5 m (segment 3); 10-12.5 m (segment 5); and 15-17.5 m (segment 7). All colonies whose center fell within 0.5 m on either side of each transect line were identified to lowest taxonomic level possible (species or genus), measured for size (maximum diameter to nearest cm), and morphology was noted. In addition, partial mortality and condition of each colony was assessed. Partial mortality was estimated as percent of the colony in terms of old dead and recent dead. The cause of recent mortality was identified if possible. The condition of each colony including disease (not attributed to recent tissue loss) and bleaching was noted along with the extent (percent of colony affected) and level of severity (range from moderate to acute). The lowest taxonomic level of coral identification was genus except for a select number of species consistently identified to species by all divers conducting the surveys. The number of species may change for each survey year depending on the experience and training of the benthic divers conducting the surveys. The list of coral species is included for each survey year. Juvenile coral colonies (<5 cm) were surveyed within three (1.0 x 1.0 m) segments along the same transect: 0-1.0 m (segment 1); 5.0-6.0 m (segment 3); and 10.0-11.0 m (segment 5). Juvenile colonies were distinguished in the field by a distinct tissue and skeletal boundary (not a fragment of a larger colony). Each juvenile colony was identified to lowest taxonomic level (genus or species) and measured for size by recording both the maximum and perpendicular diameter to the nearest 2 mm. Oliver, Thomas (808)725-5444 thomas.oliver@noaa.gov processor Structure from Motion (SfM) benthic surveys were conducted by both the fish and benthic teams to record the benthic community composition. A 3 x 20 m plot was visually established centered on a transect line (at sites >18 m, a 3 x 13 m plot was visually established). 3-4 ground control points (GCPs) were placed within the plot for scale. White balance settings were adjusted in situ using a 15% gray card. JPEG images were collected using a Canon SL2 or SL3 DSLR camera in an underwater housing with a dome port. Images were collected at each site by swimming in a back-and-forth motion 1 m above the substrate capturing images continuously to achieve a 60-80% overlap. Charendoff, Jonathan jonathan.charendoff@noaa.gov processor SfM 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. Imagery was color and exposure corrected using Adobe Lightroom if white balance was not achieved in situ or a substantial number of images were dark, respectively. Image adjustments were batch run per site for consistent correction. The SfM approach produces an accurately scaled, two-dimensional (2D) orthomosaic model created from the overlapping imagery. Raw imagery was imported into Agisoft Metashape software (AgiSoft Metashape Professional Version 1.6.1 or later) where images were aligned and used to build 3D dense point clouds (DPCs) following parameters described by Suka et al. (2019). DPCs were then imported into Viscore, a visualization software (Petrovic et al., 2014) where they were scaled and oriented using the GCP information. The ground sample distance (GSD) of the scaled DPC, which estimates the resolution per pixel by measuring the size of each pixel on the ground, ranged from 2-4 mm/pix. A geometrically accurate 2D projection of the DPC (orthoorthomosaic) is exported from Metashape and uploaded into ArcGIS for annotation. Charendoff, Jonathan jonathan.charendoff@noaa.gov processor In ArcGIS, each SfM site was set up for annotation by manually digitizing the transect and segments as a shapefile using the same sampling design as the PIFSC ESD-led in situ coral demography surveys, and setting up the attribute table in a geodatabase to mirror the in situ visual survey database (Swanson et al. 2018; Winston et al. 2019). To record and extract data from the orthomosaic, each coral colony was annotated following the in situ visual survey methods. Each colony was measured by digitizing a line across the maximum diameter of the colony. Coral ID (to lowest taxonomic level), estimated percent old mortality, and bleaching extent and severity were recorded. During annotation, the original JPEG imagery was viewed alongside the orthomosaic with the Viscore Image View feature to see fine scale colony details, observe colonies from multiple angles and locate colonies not visible in the orthomosaic (e.g. under ledges). Charendoff, Jonathan jonathan.charendoff@noaa.gov processor SfM derived annotations created in ArcGIS are quality controlled using a multi-stage process. Data are first exported from ArcGIS and quality controlled in R with specific queries to identify and correct data entry errors (e.g. misspelled species names, missing segments, data in incorrect columns, partial mortality >100%). Then data are summarized to the segment-level by annotator to identify potential issues (e.g. anomalously high or low mean values for specific metrics relative to other annotators). If issues are identified for a given annotator, that annotator reviews and corrects each site if they did find errors. Charendoff, Jonathan jonathan.charendoff@noaa.gov processor Raw data from in situ and SfM surveys include individual colony records with the corresponding physical data which reflect the description of the site. An individual colony record for adult corals includes colony species/genus identification, morphology, maximum diameter (cm), percent old dead, percent recent dead, cause of recent dead general category, cause of recent dead specific category, condition, extent and severity. Juvenile coral colony records include colony species/genus identification, morphology, maximum diameter (cm) and perpendicular diameter (cm). For species level identification of adult and juvenile corals, check the species list to ensure species identification across all divers conducting the surveys. The physical data for all records includes the following: region, island, site, date (day, month, year), latitude (dd), longitude (dd), transect, segment, segment length, segment width, minimum depth (ft), maximum depth (ft), and survey type.

Integrating structure-from-motion photogrammetry with geospatial software as a novel technique for quantifying 3D ecological characteristics of coral reefs. PeerJ 3:e1077 2015-07-07 publication John Burns https://doi.org/10.7717/peerj.1077 WWW:LINK-1.0-http--link PeerJ 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. information publisher Source Contribution: This study provides the first quantified methodological comparison to validate the transition from standard in-water methods to SfM survey methods for estimates of coral colony-level surveys. Here, we quantitatively compare data generated from in-water surveys to SfM-derived metrics for assessing coral demography, bleaching, and diversity in the main Hawaiian Islands as part of NOAA's National Coral Reef Monitoring Program. Our objectives were to compare between-method error to within-method error, test for bias between methods, and identify strengths and weaknesses of both methods. Colony density, average colony diameter, average partial mortality, prevalence of bleaching, species richness, and species diversity were recorded using both methods within the same survey areas. For all metrics, the magnitude of between-method error was comparable to the within-method error for the in-water method and between method error was significantly higher than within-method error for SfM for one of the seven metrics. Our results also reveal that a majority of the metrics do not vary significantly between methods, nor did we observe a significant interaction between method and habitat type or method and depth. Exceptions include estimates of partial mortality, bleaching prevalence, and Porites juvenile density though differences between methods are generally small. Our study also highlights that SfM offers a unique opportunity to more rigorously quantify and mitigate inter-observer error by providing observers unlimited bottom time and the opportunity to work together to resolve difficult annotations.

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.

These procedures are designed to efficiently generate coral demographic and benthic community metrics across the broad spatial scale of the Pacific Rapid Assessment and Monitoring Program. This pipeline consists of four key steps: (1) Image collection by SCUBA divers, (2) Data management, post-processing, and QC, (3) Generating 3-D models and 2-D orthophotos in Agisoft Metashape, and (4) Extracting demographic data in ArcMap. This SOP is the result of comprehensive testing of different camera systems, collection techniques, and software. While the following procedures are designed to meet ESD needs, we primarily use commercially available cameras and software, making these methods adaptable based on programmatic capacity and needs.
