The Rugosity grid calculates the "true" surface area in relation to the planar surface area. It represents the rugosity of an area of seabed (Jenness, 2004). Higher values indicate more rugose seafloor. The grid was created from the bathymetry grid of Darwin Harbour. Please see the metadata of the bathymetry grid for more details (GeoCat No: 74915). Jenness, J.S., 2004. Calculating landscape surface area from digital elevation models.Wildlife Society Bulletin, 32, 829-839.
