Bathymetric Position Index (BPI) Zones 5 m grid derived from gridded bathymetry of Kure Atoll, 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 R/V AHI,...BPI分区（BPI Zones）系通过对水深测深数据与坡度开展局域均值分析推导得到。其格网依托像元尺寸为5米的网格化多波束水深测深数据构建，该数据由R/V AHI号科考调查船采集……
