Rugosity grid derived from gridded bathymetry of Apra Harbor, Guam U.S. Territory
Rugosity is derived from gridded (1 m cell size)
multibeam bathymetry, collected aboard the Survey Vessel
Swamp Fox using the Terrain Modeler with rugosity methods
by Jeff Jenness (2003). Cell values reflect the surface area/planimetric area
ratio for the...
Slope grid derived from gridded bathymetry of Apra Harbor, Guam U.S. Territory
Slope is derived from gridded (1 m cell size) multibeam
bathymetry, collected aboard the Survey Vessel Swamp Fox. Cell
values reflect the maximum rate of change (in degrees) in elevation
between neighboring cells derived with the ArcGIS Spatial Analyst
