Habitats were mapped with heads-up digitization using the NOAA Habitat Digitizer Extension in ArcMap (Esri, v.10.8.2). Seafloor characteristics were based on visual interpretation of 3-band (red, green, blue) 0.5m satellite orthoimagery, 1-m-resolution acoustic backscatter imagery, lidar-derived digital bathymetric models (DBM) at 1-, 4-, and 8-m resolutions, and various surface morphometric layers derived from the three DBMs (relative position, aspect, rugosity, slope). Ground reference (n=870) and accuracy assessment (n=216) images of the seafloor were extracted from live video taken by a vessel-towed camera sled surveying shore-normal transects in waters 10-40 m depth. These data accompany the following report: Heberer, L.N., Alkins, K.C., Storlazzi, C.D., Cochran, S.A., Gibbs, A.E., Sparks, R., Stone, C., Silva, I., Martinez, T., Peralto, C., Levine, A., Stow, D., and Maloney, J., 2025, Benthic habitat map of Olowalu Reef, Maui, Hawaii: U.S. Geological Survey Open-File Report 2025–1010, 32 p., https://doi.org/10.3133/ofr/20251010.

See accompanying report for complete details. Process_Step: Process_Description: The benthic maps were digitized using a heads-up digitizing method. A minimum mapping unit of 100 square meters was using with the exception of smaller features carrying unique habitat significance (for example, an individual coral colony 2 m in diameter in an otherwise uncolonized area) or when caused by subdividing a habitat polygon that traversed more than one geographic zone. As input to guide the digitizing, the following datasets were used: satellite orthoimagery, lidar bathymetry, acoustic imagery, and seafloor video and stills. The draft map was created and randomly selected still images (independently classified) that were not used as part of the interpretation were used to assess the accuracy of the polygons. Any necessary corrections were made to the mapped polygons, and the final interpretation was created. See the accompanying U.S. Geological Survey Open-File Report for a complete description of the process flow used in the mapping project. Source_Used_Citation_Abbreviation: All Source Contributions listed in the Lineage section of the metadata file were used in the interpretation of the benthic map polygons.

Modified from NOAA/NOS benthic habitat mapping classification scheme of the U.S. Pacific Territories. Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: Reef hole Enumerated_Domain_Value_Definition: Area in which a visible hole is in the reef. Larger and deeper reef holes are referred to as blue holes because the deeper water inside the reef hole looks darker than the surrounding shallower water. Reef holes typically occur as a result of fresh water dissolution. Enumerated_Domain_Value_Definition_Source: U.S. Geological Survey Scientist.
