Bathymetric Position Index (BPI) Zones 5 m grid derived from gridded bathymetry of French Frigate Shoals, Hawaii, USA.
Description
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 NOAA Ship Hiialaka'i and R/V AHI, and 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 the shelf and slope environments of French Frigate Shoals, Hawaii, USA.
