Bathymetric Position Index (BPI) Structures 10 m grid derived from gridded
bathymetry of Wake Island, West Central Pacific.
BPI Structures are derived from two scales of a focal mean
analysis on bathymetry and slope. The grid is based on
gridded (10 m cell size) multibeam bathymetry, collected aboard
NOAA ship Hi'ialakai and R/V AHI. It was created using the Benthic
Terrain M...
Bathymetric Position Index (BPI) Zones 10 m grid derived from gridded
bathymetry of Wake Island, West Central
Pacific.
BPI Zones are derived from a focal mean analysis on
bathymetry and slope. The grid is based on
gridded (10 m cell size) multibeam bathymetry, collected aboard R/V AHI
and bathymetry derived from multispectral
IKONOS satellite imagery. It was created using...
10 m Rugosity grid derived from gridded bathymetry of Wake Island, West Central
Pacific.
Rugosity is derived from gridded (10 m cell size)
multibeam bathymetry, collected aboard NOAA ship Hi'ialakai and R/V AHI using the
Benthic Terrain Modeler with rugosity methods by Jeff Jenness (2003).
Cell values reflect the (surface area) / (planimetric...
10 m Slope grid derived from gridded bathymetry of Wake Island, West Central Pacific.
Slope is derived from gridded (10 m cell size) multibeam
bathymetry, collected aboard NOAA ship Hi'ialakai and R/V AHI.
Cell values reflect the maximum rate of change (in degrees) in
elevation between neighboring cells derived with the ArcGIS
Spatial Anal...
