BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (10 m cell size) multibeam bathymetry, collected aboard R/V AHI and bathymetry derived from multispectral IKONOS satellite imagery. It was created using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values represent one of 4 classes (crest, depression, flat, slope) in an index of seafloor terrains. This data set is for Wake Island, West Central Pacific.
