Victorian Bushfires Severity Map 2009 (Polygons)

The vector dataset is based on the filtered version (3x3 pixel filter) of the class fire severity classification raster product as derived from a classification of a SPOT and Landsat TM woodlands fire severity indexes 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 noise filtered 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. . The 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).
