Bathymetric Position Index (BPI) Zones 5 m grid derived from gridded bathymetry of Tau Island, Territory of American Samoa, USA.
BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard R/V AHI, merged with seafloor depths derived from multispectral IKONOS satellite imagery. BPI Structures was 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 Ofu and Olosega Islands of the Manu'a Island group, American Samoa.
