  • 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.

  • 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.

  • 20m slope grid derived from VICMAP_ELEVATION_DTM_20M

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

  • 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.

  • 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.

  • 20m aspect grid derived from VICMAP_ELEVATION_DTM_20M. ArcInfo Workstation used to generate aspect from DEM via GRID ASPECT(grid) command.

  • 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).

  • Estimated long-term mean annual rainfall interpolated to a 100m grid cell using data resampled from VICMAP_ELEVATION_DTM_20M and the ANUCLIM software.
