Description: Benthic terrain classification is a user-defined (dictionary) structures layer based on BPI’s, slope, standard deviation breaks, and depth. The benthic zones in the output layer include crests, depressions, flats, and slopes. The benthic structures in the output layer consist of: flat plains; broad slopes; steep slopes; broad platforms or depressions; lateral mid-slope platforms or depressions; scarps (or cliffs); depressions; crevices, narrow gullies over elevated terrain; narrow slopes; rock outcrop highs, narrow ridges; and local depressions, current scours. The following are also finer-scale benthic structures that occur in or on larger scale benthic structures: local ridges, boulders, pinnacles in depressions (i.e. smaller scale ridges on a larger scale depression); local ridges, boulders, pinnacles on broad flats (i.e. smaller scale ridges on a larger scale broad flats); local ridges, boulders, pinnacles on slopes (i.e. smaller scale ridges on a larger scale slopes).
