Plan Curvature Derivative Surface used to characterize the complexity of the seafloor around St. John, USVI
Plan curvature was calculated from the bathymetry surface for each raster cell using the ArcGIS 3D Analyst "Curvature" Tool. Plan curvature describes the rate of change of curvature (perpendicular to the slope direction) within a square 3x3 cell neighborhood. A negative value denotes concavity, while a positive value …
