<DIV STYLE="text-align:Left;"><DIV><P><SPAN>An initial Burned Area Reflectance Classification (BARC) dataset is created by analyzing a differenced Normalized Burn Ratio (dNBR) image, which was derived from the paired pre- and post-fire images USDA Forest Service, Geospatial Technology and Applications Center, BAER Imagery Support Program. The dNBR attempts to portray the variation in burn severity within a burned area, capturing the combined effects of the fire on the vegetation and soil components of the ecosystem. The preliminary BARC dataset is then assessed, and field validated by a Forest Service Burned Area Emergency Response (BAER) team. The Classified BARC image is adjusted and modified, as needed, based on field observations. The resulting product is a Final Soil Burn Severity. Severity Indicators High soil burn severity: Most or all pre-fire ground cover and surface organic matter (litter, duff, and fine roots) is generally consumed, and charring may be visible on larger roots. Soil is often gray, orange, or reddish at the ground surface where large or dense fuels were concentrated and consumed. Soil structure is often altered and less stable at the surface. Moderate soil burn severity: Up to 80 percent of the pre-fire ground cover may be consumed but generally not all of it. There may be potential for recruitment of effective ground cover from scorched needles or leaves remaining in the canopy that will soon fall to the ground. Soil structure is generally unchanged. Low soil burn severity: The ground surface, including any exposed mineral soil, may appear brown or black (lightly charred), and surface organic layers are not completely consumed. The canopy and understory vegetation will likely appear “green.” Very low soil burn severity or Unburned: Little to no burn expected within these areas except in small patches, or where fuels were sparse. Canopy and ground litter almost completely intact. Little to no vegetation mortality expected.</SPAN></P></DIV></DIV>
Soil Burn Severity is a measure of a fire's effects on the ground surface and soil condition. The map identifies the fire-induced changes in soil and ground surface properties that may affect infiltration, runoff, and erosion potential. The BAER Team uses this map to identify areas of unacceptable risk to a critical value and where mitigating treatments may be most effective. This product is appropriate for wildland landscapes and does not represent fire effects in developed areas.

The transactional data is branched versioned via FS enterprise GeoPortal, the National BAER application will perform data QA/QC checks on the data prior to reconcile and posting to the Default version. Checks will include geometry check, attribute validation, checks for missing or incomplete attributes
Data completeness of BAER Soil Burn Severity dataset reflects the soil burn severity data mapped by the Burned Area Emergency Response Team at the time of the BAER assessment and the National Incident Feature Service dataset was edited.
Targeted to “Geospatial Positioning Accuracy Standards, Part 3: National Standard for Spatial Data Accuracy, FGDC-STD-007.3-1998”. National Standard for Spatial Data Accuracy (NSSDA) (http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part3/chapter3).
Soil Burn Severity is generated by an individual BAER assessment team and loaded into a national data layer. Generally, the boundary is initially created from the Incident Fire Perimeter dataset and the Burned Area Reflectance Classification (BARC) Imagery Analyst uses that for their analysis area. The polygon layer is delivered as part of the BARC package. This dataset is then enriched with additional attributes, loaded into a national Enterprise Geodatabase and from there published for use in EDW.

DATA_SOURCE
Feature data source code. The GIS Data Dictionary Data Source Codes provide information on how GIS point, line, and polygon features, in Forest Service geospatial datasets, have been derived. Each Data Source code description contains information on the data used to derive features. Code descriptions are based upon the data source and positional accuracy associated with those features. The Data Dictionary Data Source codes incorporate the codes described in Chapter 7, “Guidelines for Digital Map Base Updates” of Cartographic Specifications and Symbols (EM-7140-24) (Source Codes 01-24). New source codes describing features derived from different sources of remote sensing image data are also incorporated. Remote sensing source codes are categorized by general map scale levels typically used in resource mapping (Brohman and Bryant, 2003; Bailey, 1995; Natural Resources Conservation Service, 1994). Since image data have no inherent scale, for the purposes of this data source field, image scale is determined as a function of spatial resolution and positional accuracy using NMAS thresholds for specified map level accuracy requirements.

ACCURACY
Distance (+/-), in meters, of expected difference between feature and real world object locations. The accuracy field is populated with the root mean square error (RMS) value representing the overall geolocational accuracy of features in the dataset. RMS is determined from one of several sources. These sources include:
National Standard for Spatial Data Accuracy (NSSDA) testing guidelines (FGDC, 1998). Several examples are available for calculating spatial accuracy using NSSDA (FGDC, 1998; Minnesota Planning - Land Management Information Center, 1999).
The accuracy standard by which the data were evaluated when compiled such as the National Map Accuracy Standard (U.S Bureau of the Budget, 1947) or the ASPRS Accuracy Standard for Large Scale Maps (ASPRS 1990).
