    • Bathymetric Position Index (BPI) Structures 5 m grid derived from gridded bathymetry of the US Territory of Guam.

    Metadata Updated: March 22, 2025

    BPI Structures are derived from a focal mean analysis on bathymetry and slope. The bathymetry grid (5 m cell size) is derived from bathymetry from four sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; multibeam bathymetry collected in Apra Harbor by the Naval Oceanographic Office and NOAA Office of Coast Survey; lidar collected by the Naval Oceanographic Office; and lidar collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise. 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 US Territory of Guam.
