Bathymetric Position Index (BPI) Zones 5 m grid derived from gridded bathymetry of French Frigate Shoals, Hawaii, USA.

BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA...BPI分区（BPI Zones）源自针对水深地形（bathymetry）与坡度开展的局域均值分析（focal mean analysis）。该网格基于像元尺寸为5米的网格化多波束水深测量数据（multibeam bathymetry）构建，该数据由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的科考船采集……
