  • In 2011-2012 a species tolerance model was developed by Arthur Rylah Institute, collaborating with DPI, to provide a relative measure of sensitivity of groundwater dependent species to changes in groundwater availability and quality. This grid is the mean output of the model for each Grid cell. Grid cell values have been used to attribute the Potential Groundwater Dependent Ecosystems mapping. Potential Groundwater Dependent Ecosystems (GDE) are ecosystems identified within the landscape as likely to be at least partly dependent on groundwater. Refer to the Potential Groundwater Dependent Ecosystems metadata record for a full acount of the data product.

  • Part of the Vicmap Admin dataset series. This layer contains polygon features delineating the current Metropolitan Fire Brigade Region Boundaries. Polygon features demonstrating MFB's two administrative regions. MFB Regions are a parent-group to MFB Districts. NOTE: This dataset was superceded by FRV_REGION in July 2020, and was withdrawn in December 2020 from the Vicmap Admin product.

  • This layer contains Victorian wetlands listed in the 3rd Edition of 'A Directory of Important Wetlands of Australia' (2001). Descriptions for each wetland are available in the directory which is available on the Environment Austalia website at: http://www.ea.gov.au/water/wetlands/database/index.html These wetlands are derived from the WETLAND_1994 CGDL layer, hydrological CGDL layer and other sources such as topographic maps. The 2017 update of the Victorian Wetland Inventory (Current) resulted in improved accuracy of the boundary of a number of wetlands, based on on-ground mapping. WETLAND_CURRENT provided the source data to improve the WETLANDDIR dataset.

  • This layer has been derived from FIRE_HISTORY data and represents the spatial extent of the last fires recorded, primarily on public land. The layer stores details of the last time an area was known to be burnt by wildfire or prescribed burning and represents a consecutive overlay of all FIRE_HISTORY layers, from older fire seasons to the most recent fire seasons. This data set is current to 2021/22 fire season. There is no severity data for Gippsland in this version for season 18/19 and 19/20.

  • This dataset contains interpreted geological data, using combined interpretations of airborne magnetic, radiometric and gravity survey data, mapped at 1:250,000. At scales larger than 1:120,000 the display is a combination of both 1:100,000 and 1:250,000 geophysical mapping. Recent 1:250,000 geophysical mapping has been of such quality and detail it has been used to supersede older coincident 1:100,000 mapping. This occurs in the following areas: St Arnaud 7524, Dunolly 7624, Charlton 7525, Wedderburn 7625 and part of Ararat 7423 are superseded by St Arnaud SJ54-4. Bendigo 7724, Heathcote 7824 and Nagambie 7924 are superseded by Bendigo SJ55-1. Balmoral 7223, Ararat 7423, Horsham SJ54-3 and St Arnaud SJ54-4 supersede Grampians 7323 where there is overlap. The Ouyen SI54-15 and Horsham SJ54-3 map areas are datasets derived from a combination of Geological Interpretation of Basement Geophysical Features maps and Geological Interpretation of Post-Cratonic Geophysical Features maps performed by Moore, D. H. This data has been collected by the Geological Survey of Victoria. This dataset is accompanied by other datasets representing sub-surface geological polygons, structural lines, miscellaneous lines and metamorphism.

  • Contains survey boundary polygons and associated survey metadata that include acquisition parameters. All open file airborne geophysical surveys are included where data were acquired digitally. Data for the surveys is available via GADDS http://www.geoscience.gov.au/cgi-bin/mapserv?map=/nas/web/ops/prod/apps/mapserver/gadds/wms_map/gadds.map&mode=browse

  • Estimated long-term mean annual temperature interpolated to a 20m grid cell using the DEM20 layer and the ANUCLIM software.

  • Polygon layer contains DELWP Land and Fire District Boundaries used for Forest and Fire Management operations.

  • This layer is part of Vicmap Transport and exists is a dataset containing polygon features delineating airport areas. Includes; Airports When capturing the Airport data for the state, some data was captured in polygon form some was captured in line form. To get a more complete portrayal of Airport data, this dataset should be used with the "Airport Infrastucture Area (polygon) - Vicmap Transport" dataset.

  • 1:100,000 Landuse rasterised to 20m based on VICMAP_ELEVATION_DTM_20M. For more details see the Metadata for LANDUSE100.
