资源简介：
Bathymetric Position Index (BPI) Zones are derived for islands and banks across the U.S. Pacific Islands Region from a focal mean analysis on bathymetry and slope, and were created using the Benthic Terrain Modeler. Cell values represent one of 4 classes (crest, depression, flat, slope) in an index of seafloor terrains.
The grids are based primarily on gridded multibeam bathymetry collected...
基于水深和坡度的焦点平均分析，美国太平洋岛屿区域的海岛和浅滩区域生成了水底地形指数（Bathymetric Position Index，简称BPI）区域。这些区域是通过使用底栖地形建模器创建的。单元格值代表海底地形索引中的四种类型之一（脊、洼地、平坦、坡面）。网格主要基于收集到的网格化多波束水深数据...
