Cell values reflect the (surface area) / (planimetric area) ratio for the area contained within that cell's boundaries. They provide indices of topographic roughness & convolutedness. This data set is for Galvez Bank, South Galvez Bank, and 11-Mile Reef, Territory of Guam, USA. The data were derived in support of NOAA Coral Reef Conservation Program goals. Goal 1 is to map all U.S. Coral Reef Ecosystems. This data set specifically addresses Objective 1 and 4: to develop high-resolution benthic maps and to characterize priority deep water reefs and associated habitats. This derivative of bathymetry provides a GIS layer that may be used for benthic and essential fish habitat characterization, and for the study of geologic features. By combining the dataset with bathymetry, backscatter, other derivatives, and in situ data, they collectively compose benthic habitat maps which are designed to be used to understand and predict moderate depth (~20m – 150m) benthic habitats for different organisms that inhabit coral reef ecosystems.

The NOAA Ship Sette's survey sensors included a 240-kHz pole-mounted Reson 8101ER sonar, which provides bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position,velocity, attitude and heading, and a Seabird SBE19 CTD used to measure sound velocity profiles. The metadata for the bathymetry is documented in this product metadata: ftp://ftp.soest.hawaii.edu/pibhmc/website/data/cnmi-guam/bathymetry/3Banks_Guam_5m.txt Specific equipment configurations are documented in metadata from cruise SE1002. These metadata can be accessed at: https://www.soest.hawaii.edu/pibhmc/cms/cruise-catalog/ Rugosity was calculated using the Rugosity Builder tool within the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast//tools/btm/).
