Data Identification
    Fire name: Sartin Draw
Description: Soil Burn Severity data for the Sartin Draw fire occuring on the Gallatin National Forest in Montana. This product was derived from Landsat 8 data and validated in the 
	field by a USFS BAER team.It is based on a prefire image from 2017-08-18 and a post-fire image from 2017-09-03.

Supplemental information: 
	Value 1 = unburned / very low severity
	value 2 = low severity
	value 3 = moderate severity
	value 4 = high severity

Original BARC thresholds:
    Unburned/Low: 58
    Low/Moderate: 92
    Moderate/High: 170

Soil Burn Severity Thresholds: unsure how the thresholds were adjusted
    Unburned/Low: 
    Low/Moderate: 
    Moderate/High: 

Data coordinate system: NAD83, UTM Zone 13N

Systematic threshold adjustment: __X__yes ___no

Manual edits applied:  __X__yes  ___no

Processing steps: The mapped burn intensity (for which a BARC is ultimately a surrogate) generally exceeded observed soil burn severity. This is pretty common to see in wind-driven fires 
	in eastern MT. Another common fire response attribute in eastern MT is to see low burn severity in grassland settings. So, with the 2015 Vmap data we have available, the soil 
	scientist masked out grass lifeform polygons and adjusted them to low burn severity. This addressed a fair portion of the elevated burn intensity represented in the BARC. 

1)	the raw BARC4 was converted to a shapefile;
2)	shapefile from step 1 clipped to the fire perimeter; 
3)	FS lands (area where the BARC was assessed) were erased from the shapefile from step 2
4)	The shapefile of the assessed BARC was merged with the shapefile from step 3
5)	Converted the shapefile from step 4 to the final soil burn severity *_ sbs2.tif.
