NSW seabed reef extent derived from marine lidar, multibeam and aerial imagery

Rocky reef polygons were delineated from bathymetry data for the NSW seabed. Bathymetry data was sourced from marine lidar data, multibeam echosounder data and aerial imagery. Reef polygons were extracted from the seabed landforms polygons for the statewide marine lidar and multibeam surveys for Wollongong and Shellharbour (See below for associated SEED records). For the remaining areas, reef polygons were sourced from the ‘NSW subtidal marine habitat layer’ on SEED which included reef polygons manually digitised from multibeam surveys acquired from 2005-2017.
