Bathymetric Position Index (BPI) Zones 60 m grid derived from gridded bathymetry of Rota Island, Mariana Islands, USA

BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (60 m cell size) multibeam bathymetry, collected aboard NOAA...BPI区域（BPI Zones）源自针对水深（bathymetry）与坡度的局域均值分析。该格网数据集基于像元尺寸为60米的格网化多波束水深数据，此类数据由美国国家海洋和大气管理局（NOAA）的科考船采集获取……
