Extended Assessment of Burn Severity on 2007 NPS Alaska Fires

National Park Service, Alaska Regional office

Extended assessment burn severity dataset for fires occuring in Alaskan National Parks and Preserves in 2007. Extended Assessements were completed for the South Pish River fire and the North Pish River fire in Bering Land Bridge National Preserve. The extended assessment burn severity datasets were generated by applying the Normalized Burn Ratio to pre- and post-fire Landsat imagery. The U.S. Geological Survey (USGS) has entered into a cooperative agreement with the National Park Service (NPS) to deliver satellite imagery and derivitive products centered on major fires that impact national parks and other federal lands. This data set was compiled at the request of a federal land management agency and is part of a suite of products generated for a specific fire. See the National Burn Severity Mapping web site at: http://edc2.usgs.gov/fsp/severity/fire_main.asp Monitoring Trends in Burn Severity (MTBS) is a multi-year project conducted through a partnership between the USGS EROS and the USDA Forest Service Remote Sensing Applications Center (RSAC). It is designed to consistently map the burn severity and perimeters of fires across all lands of the United States for the period spanning 1984 through 2010. MTBS is based on image processing and analysis methods currently utilized by the USGS and USFS for existing post-fire burn severity mapping efforts. The USGS Landsat Thematic Mapper image archive will provide a consistent and continuous source of 30 meter resolution data going back to 1984 for mapping burn severity of all fires greater than 1000 acres in the west and 500 acres in the east (east of 97W longitude).
