Bathymetric Position Index (BPI) Structures 5m grid derived from gridded bathymetry of Saipan Island, Commonwealth of the Northern Marianas

BPI Structures are derived from a focal mean analysis on bathymetry and slope. The bathymetry grid (5 m cell size) is derived from two sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; multibeam bathymetry collected aboard the US Naval Ship Sumner by the Naval Oceanographic Office, and also lidar, also collected by the Naval Oceanographic Office. 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 Saipan Islands, Commonwealth of the Northern Marianas (CNMI).
