This layer contains polygon features which represent subtidal relief. Isobaths are linear features which are lines of equal depth that form the boundaries of the polygons.

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 which represent depth contours (bathymetry) in the Gippsland Lakes.

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

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 NB: This layer is obsolete. For maintained data please refer to Vicmap.

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

Dataset containing an indication of the geographic extent covered by other Coastal Plans (non-CAPS) identified in 'Section 8.1 Other Coastal Plans', of the Victorian Coastal Council’s 2010-11 Annual Report. The dataset contains attributes identifying the report title, year of the report, Coastal Board region, unique identifier assigned to report, link that allows the report to be directly referenced, and link to source website page used to locate and obtain document. To support the capture of a suitable geographic extent covered by Coastal Plans each plan was reviewed and categorised in terms of the area it covered. For plans covering a local government area, Catchment Management Authority, Coastal Management Board area, or township, a nominal buffer was applied around the spatial extent of these administrative units. For reports containing a clear study area, this boundary was captured and used to depict the geographical area covered by the report.

This dataset maps the geomorphic habitat environments (facies) for 54 Victorian coastal waterways. The classification system contains 11 easily identifiable and representative environments: Barrier/back-barrier, Central Basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. Most of the 54 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition.

Aerial imagery to identify seagrass, reef and sediment habitat distributions for various marine habitat mapping projects across Victoria between 1997 to 2011 which have been subsumed into the Statewide Marine Habitat Map 2021.

The Offshore Renewable Energy Infrastructure Regions is a digital dataset that contains reference areas of proposed and declared areas suitable for offshore renewable energy established under legislation. In the event of an inconsistency between this data and the legislation, the latter prevails.
