facility. Specifically, Australia Geosciences assisted the effort by providing near real time access to Landsat 5 and 7 acquisitions for the burned area. Appropriate Landsat scenes were identified using the image browsing capabilities of the ACRES Digital Catalogue. Scenes were then transferred by file transfer protocol (FTP) to EROS/RSAC staff in the United States for generation of the burn mapping products. Once generated, products were FTP transferred or emailed directly to BAER team members in Australia for use in field assessments and planning activities. 2. METHODOLOGY 2.1 Study Area and Products In 2009, EROS/RSAC received requests from US BAER teams deployed to Victoria to provide burn severity maps for several fires (or fire complexes). BAER team staff worked closely with local land and fire managers. Specifically, assessments for the following fires were requested: Beechworth Bunyip Churchill-Delburn East Tyer-Thompson Murrindindi Wilson Promontory The spatial relationship of individual mapped fires to the Melbourne urban area and a Landsat image mosaic that provided coverage for path 92 and rows 85-87 is shown in Figure 1. Data layers generated for all Victoria fires included the following: a pre-fire image, a post-fire image as shown in Figure 2, continuous burn severity data in the form of a differenced normalized burn ratio (dNBR) (Eas. (1) and (2)) or the differenced normalized difference vegetation index (dNDVI) (Eqs. (3) and (4)) image, and a classified dNBR or dNDVI image displaying low, moderate and high soil burn severity as shown in Figure 3. 2.2 Satellite Image Processing Burn mapping products were generated for the 2009 Victoria bushfires using the same methodology that has been used in the United States to support BAER teams since the 2003 fire season. These mapping techniques are based upon the normalized burn ratio (NBR) and dNBR (Key, 2006). The NBR is a remote sensing image derivative that exploits the characteristics of the near-infrared and short-wave infrared portions of the electromagnetic spectrum as they have proven to be good discriminators of burn scars and the mosaic of severities that typically occur within a burn perimeter. The dNBR compares NBR imagery acquired before the fire with imagery of the same area acquired immediately after the fire to identify the location and magnitude of changes in vegetation. The NBR is computed using Landsat Enhanced Thematic Mapper (ETM) or Thematic Mapper (TM) near-infrared (NIR) and short-wave infrared (SWIR) spectral bands (4 and 7) respectively. The NBR is calculated as follows: NBR = (NIR — SWIR) /(NIR + SWIR) (1) 52 62 Kiometers i ; Figure 1.
