Creating Proposed Wilderness Area Boundaries Using ArcInfo and ArcView

1) Using ArcInfo append together exisitng wildrness area boundaries from
each NF and BLM resource area into one polygon coverage.

2) Convert to shapefile in ArcView 3.2

3) Load into ArcView; DRG's, USFS 1:24,000 roads, USFS administrative
boundaries, and the new shapefile created in step 2.

4) Digitize proposed wilderness areas by editing the existing wilderness
shapefile from step 2.  Append and create new polygons as needed to the
existing wilderness areas coverage.

The digitizing process is to basically just follow the lines on the
field maps.  When the boundary is a road, stream, or property line, I
just follow the line as close as possible.  When I need to digitize
boundaries on both sides of a road, I eyeball it as close to the road as
possible on both sides, making sure to not cross the road.  This leaves
the area over the road out of the proposed wilderness area.

Since a lot of the proposed wilderness area boundaries are partly made
up of the USFS administrative boundaries, we are considering the idea of
joining the polys from the USFS administrative boundaries coverage with
the polys in the existing wilderness areas shapefile that we are
currently editing.  That way we would have to digitize less lines and
would also be using more coincident arcs.  This will help all the
coverages line up nicely and make for a smooth overlay analysis.    

5) Attribute fields in the dbf file with the appropiate information
after creating new polygons.

6) Convert back into an ArcInfo coverage using SHPOLY.AML
