Title:

Burn Intensity for the 1994 Rabbit Creek Fire within Boise National Forest, Idaho

Abstract:

This data set reflects fire intensity as measured by canopy scorch for the Rabbit Creek Fire within Boise National Forest, Idaho.

Supplemental information:

Procedures_Used:
Field crews surveyed fire area (ground and air).  Islands < 40 acres usually not mapped.  Burn polygons drawn on paper copies 7 1/2 minute USGS topographical maps, then remanuscripted 1:24000 stable mylar.  Area mapped at 2 different intervals.  There was some overlap between data set.  Manuscript sets were digitized seperately and resulting coverages appended. Where discrepancies occurred, new polygons were created and attributed with the more severe burn intensity.  Digitized Arc-Info RMSE .003, clean weed 10.  Fire perimeter also collected with gps from a helicopter (wilderness portion not flown).  Perimeter collected with gps was used to modify field collected information.  "Burn polygons" outside the gps perimeter deleted from final burn intensity cover.  In general the perimeter derived from burn intensity mapping and the perimeter collected with gps agreed.

Reviews_Applied_to_Data:
Manuscripts compared with field maps to check for line and attribute accuracy.

RAB_BI

Entity and attribute overview:

BI (burn intensity), relative estimate of fire intensity as measured by canopy scorch. Generally areas > 40 acres mapped.  Scorch canopy defined as fire killed needles and leaves that remain on trees or brush.

UB - canopy not scorched.
L - Low, < 50%. Canopy "green" with scattered scorched canopy areas.
M - 51-100%, usually > 75%. Canopy "red", scattered black, green areas.
H - 100%.  Canopy completely consumed.  Canopy black.
gps - discrepancy between gps perimeter and perimeter from burn intensity mapping.  Areas within boundary collected using gps from helicopter, but outside boundary from burn intensity

Why was the data set created?

The data are intended to assist efforts surrounding broad-scale forest planning for analysis in fire-recovery: soil stabilization, reestablishing vegetation, and protection of other resources such as wildlife, riparian habitat, water quality, fisheries and timber. These data should be displayed and analyzed at scales appropriate for 1:24,000-scale data. No responsibility is assumed by the Boise National Forest GIS Staff in the use of these data.

The orginal coverage contributed by Diane McConnaughey was imported into ARC/INFO, renamed, and exported.  The file was then compressed using GZIP.

Metadata included with the original coverage (created using DOCUMENT.AML) was imported.  If the metadata was not FGDC compliant, it was updated to be compliant.
