Identification Information Citation Originator: USDA Forest Service, Geospatial Technology and Applications Center, BAER Imagery Support Program Publication Date: 2020-07-05 Title: Burned Area Reflectance Classification (BARC) Data Bundle for the CANAL Fire occurring on the Fishlake National Forest - 2020 Publication Information Publication Place: Salt Lake City, Utah, USA Publisher: USDA Forest Service Geospatial Data Presentation Form: raster digital data Online Linkage: https://fsapps.nwcg.gov/afm/baer/download.php?year=2020 Description Abstract: This is the final soil burn severity (SBS) derived from Sentinel-2 data. The SBS dataset was created by analyzing pre-fire and post-fire satellite imagery. A preliminary burn severity product was created and provided to a USFS Burned Area Emergency Response (BAER) team which then conducted field assessment and produced the SBS. Purpose: These data were created by the USDA Forest Service Geospatial Technology and Applications Center (GTAC) to support Burned Area Emergency Response (BAER) teams. Supplemental Information Fire Name: CANAL Agency: USDA Forest Service Land Management Unit: Fishlake National Forest Type of assessment: Emergency Fire size (as mapped): 71,658 acres Pre-Fire Imagery Date and Path/Row: 2020-06-26 Post-Fire Imagery Date and Path/Row: 2020-07-04 Output Dataset Projection: WGS_1984_UTM_Zone_12N Datum: D_WGS_1984 Spheroid Name: WGS_1984 Mapping Comments: Some agricultural areas are present within the burned perimeter and should be disregarded when interpreting the BARC.

Further distribution is at the discretion of the BAER team leader. Pre-imagery, post-imagery, and unthresholded data are publicly available on https://fsapps.nwcg.gov/afm/baer/download.php. Access to pre-imagery and post-imagery may be limited when sensors other than Landsat or other government remote sensing assets are used due to product licensing restrictions. Use Constraints: There are no restrictions on use, except for reasonable and proper acknowledgement of information sources and limitations as preliminary/draft data. Data Set Credit: USDA Forest Service Native Data Set Environment: ERDAS Imagine, ESRI ArcGIS Data Quality Information Positional Accuracy Horizontal Positional Accuracy Horizontal Positional Accuracy Report: Landsat data are terrain corrected using a USGS digital elevation model with less than 1/2 pixel RMS error. Accuracy may vary for other sensors. Lineage Process Step Process Description: These data products are derived from Sentinel-2 data. Pre-fire and post-fire scenes are analyzed to create a differenced Normalized Burn Ratio (dNBR) image. The dNBR image portrays the variation of burn severity within the fire. The pre- and post-fire images are terrain corrected and further processed to convert top of atmosphere reflectance. The Normalized Burn Ratio (NBR) is computed for the pre- and post-fire images using the following formula: (NIR Band - SWIR Band) / (NIR Band + SWIR Band) = NBR The Differenced NBR is computed to determine severity by subtracting the post-fire NBR from the pre-fire NBR: (PreNBR - PostNBR) = dNBR Spatial Data Organization Information Direct Spatial Reference Method: Raster Raster Object Information Vertical Count: 1 Spatial Reference Information Horizontal Coordinate System Definition Planar Map Projection Map Projection Name: WGS_1984_UTM_Zone_12N Map Projection Parameters Standard Parallel: 0.0 Standard Parallel: 0.0 Longitude of Central Meridian: -111.0 Latitude of Projection Origin: 1.0]];-5120900 -9998100 450445547.391054;-100000 10000;-100000 10000;0.001;0.001;0.001;IsHighPrecisio False Easting: 500000.0 False Northing: 0.0 Planar Coordinate Information Planar Coordinate Encoding Method: row and column Coordinate Representation Abscissa Resolution: 20.0 Ordinate Resolution: 20.0 Planar Distance Units: Meter Geodetic Model Horizontal Datum Name: D_WGS_1984 Ellipsoid Name: WGS_1984 Semi-major Axis: 6378137.0 Denominator of Flattening Ratio: 298.257223563 Distribution Information Resource Description: Downloadable Data Metadata Reference Information Metadata Date: 2020-07-05 Metadata Contact Contact Information Contact Organization Primary Contact Organization: USDA Forest Service, Geospatial Technology and Applications Center (GTAC) Contact Person: Justin Epting Contact_Address: Address_Type: Mailing and physical address Address: 125 South State Street, Suite 7105 City: Salt Lake City State_or_Province: UT Postal_Code: 84138 Contact Voice Telephone: 801 975 3755 Contact Electronic Mail Address: baerimagery@fs.fed.us
