Bathymetric Position Index (BPI) Zones 10 m grid derived from gridded bathymetry of Alamagan Island, Commonwealth of the Northern Mariana Islands, USA.

BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (10 m cell size) multibeam bathymetry, collected aboard NOAA...BPI分区（BPI Zones）衍生自针对水深地形（bathymetry）与坡度开展的聚焦均值分析（focal mean analysis）。该格网数据集基于像元尺寸为10米的网格化多波束水深测深数据（multibeam bathymetry），此类数据由NOAA（美国国家海洋和大气管理局）的科考船采集……
