Bathymetric Position Index (BPI) Structures 5 m grid derived from gridded bathymetry of Ofu and Olosega Islands, Territory of American Samoa, USA.

Metadata Updated: February 7, 2018

BPI Structures are derived from two scales of 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 created using the Benthic Terrain Modeler (http://www.csc.noaa.gov/products/btm/). Cell values represent one of 13 classes in an index of seafloor terrains. This data set is for Ofu and Olosega Islands of the Manu'a Island group, American Samoa.
