Bathymetric Position Index (BPI) Structures 5 m grid derived from gridded bathymetry of Pearl and Hermes Atoll, Hawaii, USA.
Description
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 IKONOS satellite imagery. BPI Structures was created using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values represent one of 13 classes in an index of seafloor terrains. This data set is for the bank top, edge, and lagoon environments of Pearl and Hermes Atoll, Hawaii, USA.
