DOCUMENTATION FOR SAA WILDERNESS COVERAGE:  WILDERNS

DEVELOPED BY:  SAA Roadless Team

DATE:  1995

SOURCE:  USFS district GIS databases and SAA 1:2,000,000 scale wilderness
   coverage

SCALE:  1:24,000 and 1:2,000,000

NOTES:  Arcs for this coverage were primarily extracted from USFS district
   admin and stand coverages at 1:24,000.  However, in the case of the
   Brasstown district on the Chattahoochee National Forest in Georgia, 
   wilderness arcs were not available from either of these sources.  For this
   district we had no choice but to use the arcs from the 1:2,000,000 scale
   SAA wilderness coverage.  An item, SCALE, was added to the AAT and coded
   as either 24000 or 2000000 to track base scale of the arcs used.  Also,
   the boundary of the Shenandoah National Park was not available at 1:24000 
   and the 1:2,000,000 arcs were used.

   Labels and the items FEDCODE and FEDNAME were taken from the 1:2,000,000
   scale coverage and verified by Roadless Team members.  The items NUMBER,
   USE_LEVEL, LEGAL_ACRES, MARKSYM, and OWNNAME were added to the PAT.  
   MARKSYM holds symbol values to depict label points according to use level.

   Wilderness are broken by state boundaries so that acreages per state and
   national forest could be calculated.
