Custodian:
Abstract:
The Victorian Alpine Fires 2003 were ignited on 8th January 2003 by a series of lightning strikes across north-eastern Victoria. This layer depicts fire severity, derived from Landsat imagery, across the extent of the fires to provide a reliable strategic management dataset to interpret fire effects.

Purpose:
The fire severity classification is primarily derived from Landsat 7 Thematic Mapper multispectral satellite data, using a differentiation technique. Pre-fire (February 2001) and post-fire (7 April 2003) Landsat images are analysed for vegetation changes, a process carried out by DSE Land Information Group. Aerial photograph interpretation supplements the coverage where Landsat data is unavailable. The combined fire severity classification is validated on a minimum number of field sites.
The classification primarily differentiates crown burn (higher severity) and crown scorch (lower severity) classes of eucalypt forests, though the remote sensing method is also applied to treeless areas. For these areas in particular the classification should be used as a guide only, as localised anomalies may occur. For instance, drought-affected grassland may not be reliably differentiated from burnt grassland if the condition of each is bare soil. Used with care and with field checking of your target area for your particular purpose, this dataset provides a reliable strategic overview of the whole fire.
