Marine Benthic Habitat Mapping

This project developed a solution for a large Australian research organisation, to better understand the geophysical characteristics and benthic communities in coastal Victoria, Australia.


VPAC’s participation involved the development of an automated procedure to process large volumes of multibeam sonar data coupled with geo-referenced video “ground truth” data collected off the coast of Victoria.

An automated decision tree classification system was applied to classify substrata and dominant biota communities based on geo-referenced underwater video ground truth data.

The technique of combining derivative products from the backscatter and the bathymetry datasets was found to improve separability for broad biota and substrata categories over the use of either of these datasets alone.

Development of coastal regions has resulted in significant anthropogenic impacts in south-west Victoria. The Victorian Marine Habitat Mapping Project surveyed over 500 square kilometres in 14 marine regions within Victorian state waters with the objective of establishing baseline physical and biological information regarding coastal waters.
