The data displays Coal polygon data in a very limited area close to Zumsteins in the Garmpians The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by other datasets representing geology outcrop and boundaries, structural lines, miscellaneous lines and points, metamorphism, and placer deposits. Sourced from the Northern Grampians Special 1:50,000 Map 1997 COALINVSBD has a better state wide perspective (from the Victorian Coal - A 2006 Inventory of Resources)

Last updated: November 2019 This dataset represents the spatial extent of prescribed burns planned for ignition and associated mechanical and vegetation works on Public Land in Victoria and some CFA burns. This data is prepared annually for prescribed burns planned for the immediate three-year period. This dataset is now the joint fuel management plan and now includes the CFA burns as well as VicForest coupe burns.

This dataset is the Victorian Aquifer Framework (VAF) Salinity Distribution. It refers to the salinity distribution for Aquifer Number of 101 (Upper Tertiary/Quaternary Basalt Aquifer). The salinity distributions reflect the beneficial use segments prescribed in the State Environment Protection Policy (Waters) (2018) Please refer to the master metadata record VAF 'Victorian Aquifer Framework (VAF) Salinity Distribution for detailed information.

Winterfill sustainable diversion limit (SDL) volumes have been developed across Victoria and represent the upper limit on winterfill diversions, beyond which there is an unacceptable risk that additional extractions may degrade the environment. Combined with the volume of current extractions the SDL provides water managers with a volume of available water in catchments across Victoria. This dataset shows for each 1611 Victorian SDL intermediate catchments: the diversion limit, the level of winterfill commitment as at 2014, and the volume of water available for new entitlements or trade. The catchments were originally developed in 2004. A major review in 2014 resulted in the addition of several additional catchments including the upper Snowy River, Phillip Island, French Island, and several new catchments in the Wimmera basin. Summary information from this dataset is available through the publicly accessible Mapshare platform. To use or understand particular fields within this database, please contact the data custodian.

This data contains areas of regolith materials classified according to their radiometric response. The interpretation concentrates on areas of alluvial and colluvial sediments and is intended to give an indication of the provenance of the material contained in these deposits.

Projection data is described in the gridcode column of the attribute table. This number is 1000 times the actual value (retained in this form to capture significant figures through map processing). For example, "Gridcode -23599" equates to -24% (rainfall) and "Gridcode 1986" equates to 2.0 degrees Celsius (temperature). The results are from 23 climate models that were available for the IPCC Fourth Assessment Report (2007). It is assumed that that the model results give a representation of the real world response to a specific emissions scenario. The IPCC (2007) estimates of global warming are relative to the period 1980-1999. For convenience, the baseline is often called 1990. Projections are given for 2030 and 2070 but, of course, individual years can vary markedly within any climate period, so the values can be taken as representative of the decade around the single year stated, i.e. projections for 2030 are representative of 2026-2035. Natural variability (independent of greenhouse gas forcing) can cause decadal means to vary and estimates of this effect are included in the estimates of uncertainties. The projections comprise a central estimate and a range of uncertainty. The central estimate is the median – or 50th percentile - of the model results, while the uncertainty range is based on two extreme values – the 10th and 90th percentiles. 10% of values fall below the 10th percentile and 10% of values lie above the 90th percentile. Greater emphasis is given to projections from models that best simulate the present climate. The weightings are based on statistical measures of how well each model can simulate the 1975-2004 average patterns of rainfall, temperature, and sea level pressure over Australia. Subregions of Victoria are indicated. Victoria has an integrated catchment management system established under the Catchment and Land Protection Act 1994 (the CaLP Act). Under the CaLP Act, Victoria is divided into ten catchment regions, with a Catchment Management Authority (CMA) established for each region.

This dataset displays areas of contact and regional metamorphism, and the style of metamorphism, mapped using using combined interpretations of airborne magnetic, radiometric and gravity survey data at 1:100,000. 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. This data has been collected by the Geological Survey of Victoria. This dataset is accompanied by other datasets representing geological polygons and boundaries, sub-surface geological polygons, structural lines and miscellaneous lines.

Spatial dataset of Above Ground Biomass (AGB) in Victoria's public forest estate. In Victoria, forests are defined as land area greater than 0.5 ha, dominated by trees usually having a single stem and a mature or potentially mature stand height exceeding two metres and with existing or potential crown cover of overstory strata equal to or greater than 20 percent. This definition includes native forests, plantations and areas of trees sometimes described as woodlands.
