U.S. Geological Survey 20240126 raster digital data https://doi.org/10.5066/P97UMU6K https://burnseverity.cr.usgs.gov/products/fws-fire-atlas The U. S. Fish and Wildlife Service (FWS) requests burn severity assessments through an agreement with the U.S. Geological Survey (USGS) to be completed by analysts with the Monitoring Trends in Burn Severity (MTBS) Program. These data products are burned area boundary shapefiles derived from post-fire sensor data (including Landsat TM, Landsat ETM+, Landsat OLI). The pre-fire and post-fire subsets included were used to create Normalized Burn Ratio (NBR) and then a differenced Normalized Burn Ratio (dNBR) image. The objective of this assessment was to generate burned area boundaries for each fire. Data bundles also include post-fire subset, pre-fire subset, NBR, and dNBR images. This map layer is a thematic raster image of burn severity classes for all inventoried fires occurring in CONUS during calendar year 1990. Fires omitted from this mapped inventory are those where suitable satellite imagery was not available, or fires which were not discernable from available imagery. These data were created by the U.S. Geological Survey to support U. S. Fish and Wildlife Service. See https://burnseverity.cr.usgs.gov/products/fws-fire-atlas for project information and data access.

Sioux Falls SD 57198 US 800-252-4547 burnseverity@usgs.gov U.S. Geological Survey ERDAS Imagine and ESRI ArcGIS Pro MTBS analysts utilized the post fire image, NBR, and dNBR images for generating burned area boundaries for each fire. MTBS mapping protocols were not strictly followed/applied to generate this data/information. However, analysts followed guidelines established by subject matter experts to maintain consistency in generating burned area boundaries. No tests for logical consistency have been performed on this map layer. none Each image used to create the burned area boundaries (utilizing Landsat TM, Landsat ETM+, Landsat OLI), was precision terrain-corrected using 3-arc-second digital terrain elevation data, and Geo registered using ground control points. This resulted in a root mean square registration error of less than 1 pixel (30-meters).
