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 NOAA Ship Oscar Elton Sette. BPI Structures was created using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast//tools/btm/). The Cell values represent one of 12 classes in an index of seafloor terrains. This data set is for Galvez Bank, South Galvez Bank, and 11-Mile Reef, Territory of Guam, USA.
