All maps are accessible through this website. download mapDigital Coral cover maps depict percentage of scleractinian (hard) coral cover along survey tracks, overlain on existing bathymetric grids and/or satellite images, for islands and banks across the U.S. Pacific Islands Region. The coral cover data is derived from the classification of in situ seafloor imagery collected from NOAA Coral Reef Ecosystem Program (CREP) optical validation surveys from 2001 to 2015. Each point on the map represents data from a single video frame or photo that has been analyzed using a point count method, and the imagery is classified by the type of substrate type (sand, rubble, etc.) and biological cover type (coral, macroalgae, etc.). All available cover data derived from geolocated seafloor imagery that has been collected and analyzed by CREP within the U.S. coral reef ecosystems of the Pacific is included in the maps; in some cases cover data derived from imagery collected by partners and analyzed by CREP may be included as well. Coral cover maps for each location are available via the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) website at www.soest.hawaii.edu/pibhmc. In addition, the associated data and information about the data sources and collection methods are included in a zip file with each of the maps. Prepared by the NOAA Coral Reef Ecosystem Program (CREP) and funded by the NOAA Coral Reef Conservation Program (CRCP), the data were derived in support of CRCP goals to map all U.S. Coral Reef Ecosystems by developing high-resolution benthic maps to characterize priority reefs and associated habitats. The maps described herein depict the percent cover of all scleractinian coral species and may be suitable for many applications such as essential fish habitat characterization, management of corals listed under the Endangered Species Act, and for the study of geologic features. These data can be combined with bathymetry, backscatter, and other derivative datasets to compose benthic habitat maps that can be used to understand and predict benthic habitats for different organisms that inhabit coral reef ecosystems. These maps were made possible with funding from the NOAA Coral Reef Conservation Program (CRCP). Additional support was received from the NOAA Habitat Blueprint for the maps of the West Hawaii Focus Area.

Accuracy Spatial accuracy of coral cover data varies from approximately 10 to 100 meters depending on the positional uncertainty associated with the instrument used to collect the imagery. Completeness Report Coral cover data used are limited to in situ imagery or observer datasets collected by the Coral Reef Ecosystem Program at the NOAA Pacific Islands Fisheries Science Center and include data collected between 2001-2015. Limits of time, conditions and funding affect how many surveys were possible within a given area. Some areas have very limited image survey coverage. Conceptual Consistency In cases in which data were collected in the same location over multiple years, the most recently collected data were used. However, final maps make no distinction as to the date data were collected and display all available data for each island or bank. Classification of imagery was completed by several trained analysts who were tested and calibrated each year. The method to develop the Coral Cover data layers are generally described on the Pacific Islands Benthic Habitata Mapping Center website at http://www.soest.hawaii.edu/pibhmc/pibhmc_mapping.htm#optical All coral cover maps contain data generated from imagery collected during NOAA CREP towed optical assessment device (TOAD)---or towed camera sled---surveys unless otherwise noted. In a few cases, maps include additional sources of benthic cover data generated from imagery collected during other NOAA CREP surveys, including autonomous underwater vehicle (AUV), remotely operated vehicle (ROV), or towed-diver surveys, or from imagery collected by partners.
