  • 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

  • Details the location and attributes of coal subcrops in Victoria. Spatial accuracy defined as attribute "Loc_Acc" Data is from the "Victorian Coal - A 2006 Inventory of Resources" Available via the online store <a href=&#09;http://dpistore.efirst.com.au&#09;>On Line store</a>

  • This layer is part of Vicmap Elevation 10-20 Contours & Relief, a subset of Vicmap Elevation. It contains point features delineating ground surface points photogrammetric control points. Includes; Spot heights & Rocky Outcrops.

  • 1:250,000 Groundwater Flow System layer converted to a grid based on DEM25

  • Deep Leads Areas for Alluvial Gold. Compiled from maps associated with GSV Bulletin 62 (1988) by Frank Canavan. Bendigo 1:250,000 DEEPLD250 has also been added to the dataset.

  • This dataset is a subset of the Victorian Groundwater Data Inventory, developed by DELWP. The Data Inventory collated available data relating to four themes: groundwater recharge, aquifer/aquitard properties, groundwater use and aquifer/aquitard thickness. Information has been sourced from 65 hydrogeological studies and contains a spatially enabled representation of data coverage. This dataset represent the Recharge component of the Data Inventory. A total of 35 groundwater recharge data sources were identified for Victoria and 31 were successfully sourced and added to the database.

  • This layer is part of Vicmap Transport and exists is a dataset containing point features delineating Helipads.

  • Hydrographs from over 2000 state observation bores were reviewed in order to group bores which have a similar water level trend and are screened in the same aquifer. The groupings of observation bores are referred to as 'suites' and are classified according to the Upper, Middle, Lower and Basement aquifers aligning with the Victorian Aquifer Framework. By applying a statistical technical, a normalised hydrograph was developed for each suite using the observed water levels from all bores within the suite. This hydrograph is representative of the groundwater trend within the suite. A spatial boundary has been created for each suite which encompasses all bores within the suite. The boundaries were manually constructed and cover the extent of the mapped aquifers.

  • The Vicmap Vegetation Tree Urban represents trees as points across Metropolitan Melbourne and the urban environment within four regional councils: Wangaratta, Sale, Shepparton and Ballarat. This product is derived from machine learning of high resolution aerial photography with no post processing human intervention.

  • Details the location and attributes of each coalfield in Victoria. Spatial accuracy defined as attribute "Loc_Acc". This dataset has 3 lookup tables: COALINVFLDS_BLACK and COALINVFLDS_BROWN. Note that 1 field can have many seams. Also COALINVFLDS_WATERUSE LUT joins to this dataset. For all COALINV data the LUT table COALINV_KEY contains the key info for each dataset. Data is from the "Victorian Coal - A 2006 Inventory of Resources" Available via the online store <a href=&#09;http://dpistore.efirst.com.au&#09;>On Line store</a>
