The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Coral Reef Structural Complexity derived from Structure-from-Motion (SfM) imagery collected at Stratified-Random Sites (StRS) at sites across the Main Hawaiian Islands from 2019-04-21 to 2019-08-06 (NCEI Accession 0268310) |
| Abstract: | The data described here are structural complexity estimates derived from Structure from Motion (SfM) benthic habitat imagery collected during diver transect surveys conducted at stratified random sites (StRS) by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD) during the 2019 NOAA National Coral Reef Monitoring Program (NCRMP) mission to the Main Hawaiian Islands (MHI).The SfM imagery was used to generate orthomosaic images using Agisoft Metashape software. Resulting digital elevation models are used with Rstudio to estimate three habitat structural complexity metrics: rugosity, height range, and fractal dimension. SfM imagery, collected at Stratified-Random Sites (StRS) across the Main Hawaiian Islands from 2019-04-21 to 2019-08-06, was used to extract data including three metrics of habitat structural complexity (rugosity, fractal dimension, and height range). The photographs were processed using Agisoft Metashape software to generate digital elevation models that were analyzed in R studio to extract estimates of rugosity, fractal dimension, and height range. Data was collected for each site within five 4m2 boxes. Source imagery is described separately, and access procedures will be described on the following page: https://www.fisheries.noaa.gov/inport/item/63095 The scripts used will be published on GitHub and updated in this data package's InPort metadata page: https://www.fisheries.noaa.gov/inport/item/67851. |
