Water Frontages are a subset of the VMPROP.V_PARCEL_MP_CROWN_APPROVED dataset. From the LIMS database, water frontage licences were selected and the associated parcels were selected on the SPI number or the P Number. The parcels selected were compared to the list of streams reserved under the 1881 reservation of water frontages for public purposes. A majority of streams were identified. Some stream beds and banks have not yet been parcelised, so any unidentified parcels were selected which aligned with the hydrology layer and had an irregular shape and were added to the layer. The VicMap hydrology layer was used to label water frontages.
This dataset was developed from the database of Ocean Sciences Institute of Sydney University (AUSEABED) and from surveys conducted by MAFRI.
This layer represents the spatial extent, species distrubtion and density of seagrass meadows within the Corner Inlet and Nooramunga. This layer is a result of a baseline survey of seagrass within the Corner Inlet and Nooramunga. Ecological research into the health of seagrass meadows requires the type of detailed information collected in this baseline survey. This information will be used to establish future monitoring programs and it is envisaged that these areas will be re-surveyed every 5 years to detect macro changes.
The landcover dataset originates from the Murray Darling Basin Project M305 - Structural Vegetation for the Murray Darling Basin. Landcover describes the cover type present at that point in time that the mapping was undertaken. It should not be confused with public land which describes the management or use of the land. For example, an area may be managed as a pine plantation (land use) but may be bare for any period of time (landcover).
Estimated long-term mean annual rainfall interpolated to a 20m grid cell using the VICMAP_ELEVATION_DTM_20M layer and the ANUCLIM software.
This layer represents the spatial extent, species distrubtion and density of seagrass meadows within the Gippsland Lakes. This layer is a result of a baseline survey of seagrass within the Gippsland Lakes.

This is a derived dataset that delineates the current Bioregional Conservation Status of EVCs within the modeled 1750 EVC dataset. The dataset is derived from a combination of both Victorian bioregions (VBIOREG100) and the modeled 1750 EVC dataset (NV1750_EVC), with an assigned conservation status on the basis of unique Bioregion EVC units. The dataset underpins the implementation of Victoria's Native Vegetation Management Framework, and the preparation of Regional Vegetation Plans in addition to other biodiversity planning. The dataset requires upgrading when either of the two input datasets change. Note erratum under Data Quality-Completeness-Classification
This dataset is a simplified and generalised version of the NV2005_EXTENT dataset. The parameters of the simplification and generalisation have been set to produce a a product suitable for mapping at scales between 1:30000 and 1:400000
