IMSA - Very High Resolution Seafloor Classification and Satellite Derived Bathymetry of Swanbourne, Australia

Mapping of benthic habitat and bathymetry, derived from satellite imagery captured on 03 June 2017 at a spatial resolution of 2 m. Mapping extent covered as much of the Defence gazetted waters as possible, to a depth of approximately 18 m based on water clarity. Recently dead or senesced (e.g. winter dieback of leaves) and mobile seagrass have the same satellite signature as live seagrass at spectral resolutions of the sensor (WorldView-2). This ensured areas of winter dieback and/or senescence were captured as areas of seagrass for the purposes of impact assessment.
