Calculated over 3 x 3 neighbouring cells. In the benthic environment, ecological diversity can generally be correlated with environmental complexity. As such, rugosity is often used to help identify areas with potentially high biodiversity. Ruggedness values in the output raster can range from 0 (no terrain variation) to 1 (complete terrain variation). Typical values for natural terrains range between 0 and about 0.4.</SPAN></P></DIV></DIV></DIV>
