Bathymetric Position Index (BPI) Structures 5 m grid derived from gridded
bathymetry of Ta'u Island, Territory of American Samoa, USA.
BPI Structures are derived from two scales of 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
merged with seafloor depths derived from multispectral
IKONOS satellit...
Bathymetric Position Index (BPI) Zones 5 m grid derived from gridded
bathymetry of Tau Island, Territory of American Samoa, 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, merged with seafloor
depths derived from multispectral IKONOS satellite imagery. BPI Str...
Preliminary hard and soft bottom seafloor substrate map
derived from an unsupervised classification of gridded
backscatter and bathymetry derivatives at Tau Island, Territory of American Samoa, USA.
Preliminary hard and soft seafloor substrate map derived
from an unsupervised classification of multibeam backscatter and
bathymety derivatives at Ta'u Island, Territory of American Samoa, USA . The
dataset was derived using Reson 8101 backscatter data, b...
Slope grid derived from gridded bathymetry of Ta'u Island,
Territory of American Samoa, USA
Slope is derived from gridded (5 m cell size) multibeam
bathymetry, collected aboard R/V AHI, and bathymetry
derived from multispectral IKONOS satellite imagery.
Cell values reflect the maximum rate of change (in degrees) in
elevation between neighboring ...
