Bathymetric Position Index (BPI) Structures 40 m grid derived from gridded bathymetry of Howland Island, Pacific Remote Island Areas, Central Pacific.
Description
BPI Structures are derived from two scales of a focal mean analysis on bathymetry and slope. The grid is based on gridded (40 m cell size) multibeam bathymetry, collected aboard R/V AHI and NOAA ship Hi'ialakai. BPI Structures was created using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values represent one of 12 classes in an index of seafloor terrains. This data set is for Howland Island, Pacific Remote Island Areas, Central Pacific.
