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://burnseverity.cr.usgs.gov/ Purpose: The purpose of this project is to develop a robust mapping methodology and consistent data products that allow federal land managers and fire ecologists to evaluate and compare burn severity within individual fires and between fires across various ecosystems. These products will help land managers to more effectively plan, implement and monitor fire recovery activities.

Logical_Consistency_Report: These Landsat data are collected from a nominal altitude of 705 kilometers in a near-polar, near-circular, sun-synchronous orbit at an inclination of 98.2 degrees, imaging the same 183-km swath of Earth's surface every 16 days. The pixels representing the bands for the image are in the data set only once. Completeness_Report: Fire perimeter was digitized manually on screen, with 30-meter weed and grain tolerances. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Energy reflected from Earth's surface passes through a whisk-broom scanning system and all-reflective optics before being collected by the solid-state detectors at the focal plane. Lineage: Process_Step: Process_Description: These data products are derived from Landsat Thematic Mapper data. A pre-fire scene and a post-fire scene are analyzed to create a Differenced Normalized Burn Ratio (DNBR) image. The DNBR image portrays the variations of burn severity within the fire. The Landsat images are terrain corrected and geometrically rectified to an Albers Conical Equal Area map projection using the National Landsat Archive Production System (NLAPS). The images are further processed to convert bands 1-5 and 7 to at-satellite-reflectance. The Normalized Burn Ratio (NBR) is computed for each date of imagery using the following formula: (Band 4 - Band 7) / (Band 4 + Band 7) = NBR The differenced NBR is computed by subtracting the post-fire NBR from the pre-fire NBR: PreNBR - PostNBR = DNBR Higher DNBR values are correlated with more severe burns. The DNBR image is evaluated to determine the threshold value between burned and unburned areas. The perimeter of the fire is delineated using the DNBR image. The DNBR image, the pre-fire and post-fire TM images, and a fire perimeter vector file are provided in digital format. reea06b_dnbr (grid) made up of the following patch sequence: d0320207213 (both 03202 and 07213 contained clouds, 03202 contained 2002 Fox Creek burn); if clouds in 03202 or Fox Creek burn, then insert d0523907213 (05239 had no clouds); if clouds in 07213, then insert d0523907197 (07197 contained clouds); if (clouds in 07213 AND 07197), i.e. where they overlap, then insert d0523907229 (no clouds but slightly smoky in 07229).
