  • This polygon layer represents marine habitat in the East Gippsland region mapped from satellite imagery and aerial photography with underwater video ground-truthing. The mapping was funded by Natural Heritage Trust to increase the capacity of natural resource managers to make informed decisions regarding asset identification, risk assessment, and management action targets for nearshore marine habitats in the region.

  • This layer contains line features which represent depth contours (bathymetry) in the Gippsland Lakes.

  • This layer identifies the entrances to major watercourses along the Victorian coastline. The layer is a points coverage with the point location representing approximately the centre of the watercourse entrance. Sites were identified from 1:25,000 topographic maps and consultation with coastal rangers. The layer is intended to provide oil spill response personnel with a guide to assist in determining response techniques to prevent oil slicks entering these river inlets in the event of an oil spill. Locations are classified as continously open or intermittently open.

  • This layer contains line features for depth contours (bathymetry) in Western Port.

  • This dataset was developed from the database of Ocean Sciences Institute of Sydney University (AUSEABED) and from surveys conducted by MAFRI.

  • This layer defines the approximate spatial extent, species distribution and density of seagrass and macroalgae in Western Port mapped from aerial photography in 1994 by the EPA.

  • This layer contains line features for depth contours (bathymetry) in Port Phillip Bay.

  • Scientific review and dataset on developing a criteria for identifying key fish habitat locations and focussed on major Victorian bays and inlets (Port Philip Bay, Western Port, Corner Inlet and Gippsland Lakes). The recreational marine fish species habitat in the dataset are King george whiting, snapper, sand flathead, calamari, black bream and gummy shark. Commissioned by the Victorian Fisheries Authority (VFA) and later digitised by DELWP, the consultancy report was produced by the University of Melbourne. Kalu. Commissioned by VFA. developing criteria for identifying key fish habitat locations

  • The State Environment Protection Policy (Waters) released in 2018 identifies the beneficial uses and environmental quality objectives that apply to different areas of Victoria. These areas are called segments. This data includes the spatial boundaries of these segments and can assist users of the policy identify which values apply in particular areas.

  • This layer contains coastal and marine related features represented by points and lines. All features are identified and coded according to the Australian Standard Geographic Information Systems - Geographic Data - Interchange of feature-coded digital mapping data AS2482-1989. Data has been derived from Land Victorias State Digital Map Base - Topographic data and converted from Microstation .DGN format to Arcinfo format. NB: This layer is obsolete.
