  • This table provides Tolerable Fire Interval (TFI) information for Ecological Fire Groups and Ecological Vegetation Divisions on public land

  • Vicmap Imagery represents a suite of statewide aerial photography and satellite image products. The satellite imagey datasets are statewide Landsat 7 products. Datasets in the series are listed below. See their metadata entries for more detailed metadata. 2001 SPOT Panchromatic/Monochromatic - Vicmap Imagery (Satellite) (SPOTP- 2001VI10); Satellite Image Colour Mosaic (30 metre pixel) - Vicmap Imagery (Satellite) (TM7-2000VI30); Satellite Image Colour Mosaic (300 metre pixel) - Vicmap Imagery (Satellite) (TM7-2000VI300); Satellite Images Individual Scenes (30 metre pixel) - Vicmap Imagery (Satellite) (LANDSAT7ETM+);

  • 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.

  • 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.

  • This layer contains the line and polygon features depicting the Land Conservation Council Study Area boundaries according to the Statewide Assessment Report of 1989, with additional information showing historic studies. There are no boundaries for Special Investigations included in this dataset. An additional layer has been created showing later Environment Conservation Council Boundaries and the boundaries of some of the special investigations. Refer to ECC500

  • 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.

  • 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. The data will show fire scars but not severity. This data set is current to 2021/22 fire season.

  • Vicmap Elevation DEM 10m is a product which is a raster representation of Victoria's elevation. DEM 10m has a spatial resolution of 10 metres with respective horizontal and vertical accuracy of 12.5m and 5m or better. The DEM is constructed from source data of various resolutions, accuracies and ages to produce an improved DEM containing increased detail in localised areas. The DEMs are hydrologically enforced and correctly defines the natural surface drainage and hydrological flow. This product has been quality assured by DELWP and additional third-party consultants. Update of the dataset Vicmap Elevation DTM 10m.

  • Last updated: October 2020 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.

  • The fire severity classification is derived from a classification of a SPOT and Landsat TM woodlands fire severity index to map the fire severity of the February 2009 Victorian bush fires using ground control and air photograph analysis provided by DSE to Ecowise for validation. The classification is the final product derived using SPOT 4/5 satellite imagery with Landsat 5 imagery used on small areas where cloud or where SPOT imagery coverage was unavailable. Five of the eight classes have been labeled based on severity classes provided with the ground survey data. The remaining classes account for vegetation structures with no specific burn severity assigned. The area covered by the classification is approximately 460 by 300 km and is clipped to the extents of the fire effected lands (approximately 400 000 hectares).
