Bathymetric (depth) information were sourced from the NSW statewide marine lidar bathymetry data collected in 2018 and multibeam echosounder surveys conducted by the NSW Department of Planning and Environment since 2005. Data were mosaicked in ArcGIS 10.8, with the marine lidar data superseding the multibeam data where overlaps occurred. This dataset will be updated as new surveys are conducted.

Please refer to the ‘NSW Marine LiDAR Topo-Bathy 2018 Geotif’ (https://datasets.seed.nsw.gov.au/dataset/marine-lidar-topo-bathy-2018) and ‘HABMAP Multi-beam Survey Coverage Areas’ (https://datasets.seed.nsw.gov.au/dataset/habmap-multi-beam-survey-coverage-areasd74ae) records on SEED for further information on the data sources.
