Curvature Derivative Surface used to characterize the complexity of the seafloor around St. John, USVI
Curvature was calculated from the bathymetry surface for each raster cell using the ArcGIS 3D Analyst "Curvature" Tool. Curvature describes the rate of change of curvature (in 1/100 z units) within a square 3x3 cell window. A negative value denotes concavity, while a positive value denotes convexity. The 2x2 meter …
