  • 100m aspect grid derived from a resample of VICMAP_ELEVATION_DTM_20M. ArcInfo Workstation used to resample from 20m to 100m, then generate aspect from resultant DEM via GRID ASPECT(grid) command.

  • 20m aspect grid derived from VICMAP_ELEVATION_DTM_20M. ArcInfo Workstation used to generate aspect from DEM via GRID ASPECT(grid) command.

  • 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.

  • 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 contains modelled old-growth forest which has been updated with forest harvesting and fire. The base layer used in western part of the state is og100 which was updated by lastburnt100, lastlog25 and boundaries of the 2006 Grampians fire from ECC. The base layer for the eastern part of the state is mog2003 updated by lastlog25 & lastburnt100. The old-growth forests in the base layers were identified to meet the Victorian definition of old-gwoth forest based on a set of modelling criteria, rules and input datasets. The data is not reliable at scales less than 1:100,000. Old-growth polygons have not been confirmed through field checking and the reliability of modelled old-groth stands have not been assessed.

  • 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. 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.
