  • 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.

  • The land systems of Victoria spatial data layer (LSYS250) was re-attributed by DPI Bendigo based on McKenzie's Soil Atlas of Australia (CSIRO, 2003). Soil was classified on the Northcote scheme. This layer was converted to a grid format based on the VICMAP_ELEVATION_DTM_20M layer.

  • 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).

  • 20m slope grid derived from VICMAP_ELEVATION_DTM_20M

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

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

  • Thiessen polygons were generated for climate stations point locations for Victoria, and attributed with the station ID. Polygons were rasterised based on VICMAP_ELEVATION_DTM_20M. Site information was obtained from the Queensland Department Natural Resources SILO website (http://www.nrw.qld.gov.au/silo/ppd).

  • 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+);

  • 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.

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