What does this data set describe?

Title:
Burn Intensity for the 1992 Foothills Fire within Boise National Forest

Abstract: 
This data set reflects fire intensity as measured by canopy scorch for the 1992 Foothills Fire, 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.  Digitized Arc-Info RMSE .003, clean weed 10.

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

    ground condition

  5. What is the general form of this data set?

    Geospatial data presentation form: vector digital data

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • Point (428)
      • String (816)
      • GT-polygon composed of chains (429)
      • Point (224)

    2. What coordinate system is used to represent geographic features?

      The grid coordinate system used is Universal Transverse Mercator

      Universal Transverse Mercator
      UTM zone number: 11
      Transverse Mercator projection parameters:
      Scale factor at central meridian: 0.999600
      Longitude of central meridian: -117.000000
      Latitude of projection origin: 0.000000
      False easting: 500000.000000
      False northing: 0.000000

      Planar coordinates are encoded using Coordinate Pair.
      Abscissae (x-coordinates) are specified to the nearest 1.
      Ordinates (y-coordinates) are specified to the nearest 1.
      Planar coordinates are specified in meters.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.
      The flattening of the ellipsoid used is 1/294.9786982.

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 provided 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.
