Bathymetric Position Index (BPI) Structures, 5m - Tutuila, American Samoa

Bathymetric position index (BPI) structures are derived from two scales of a focal mean analysis on bathymetry; slope; and depth. The grid is based on gridded (5 m...水深位置指数（Bathymetric Position Index, BPI）结构由针对海底地形、坡度与水深开展的双尺度局域均值分析衍生得到。该网格数据集基于分辨率为5米的网格化（5 m……）数据构建。
