    • Benthic cover and other related datasets derived from Structure-from-Motion (SfM) imagery of coral reef ecosystems in Pacific Islands Regions

    Metadata Updated: January 1, 2026

    This collection includes various coral reef data that was extracted by analyses of Structure-from-Motion (SfM) imagery of coral reef ecosystems across the Pacific Islands Regions by the Ecosystem Sciences Division (ESD) of the Pacific Islands Fisheries Science Center (PIFSC) of NOAA. This collection includes coral reef benthic cover, vital rates (growth, mortality, recruitment), structural complexity, and coral demographic data. Coral reef benthic cover, vital rates, and demographic data were produced by annotations of orthoprojections generated from SfM imagery, whereas structural complexity was derived from the digital elevation models, which were produced from orthomosaics, also generated from SfM imagery. Source SfM imagery is archived separately due to filesize. Refer to specific accession pages for funding agencies, dates, and regions.
