Abstract :
Physical parameters of the seabed can be automatically classified using terrestrial landscape morphometric tools. This case study demonstrates the classification of multibeam acoustic data into six ecologically relevant classes in a marine park off the coast of Western Australia. The results of this application, improve the access to fine scale reef characteristics which helps to develop better management strategies for ben-thic habitats. This new morphometric classification method is compared with traditional qualitative feature identification.
