##$aThe map layer that displays Special Feature Symbols shows
the approximate location of small (less than 2 acres in size) areas of soils
... [subfield $a shortened in this example] $dQuarter quadrangles edited and joined internally and to
surrounding quads. All known errors corrected.$eThe combination of spatial linework layer, Special Feature
Symbols layer, and attribute data are considered a complete SSURGO dataset.$fThe actual on ground transition between the area
represented by the Special Feature Symbol and the surrounding soils generally
is very narrow with a well defined edge. The center of the feature area was
compiled and digitized as a point. The same standards for compilation and
digitizing used for line data were applied to the development of the Special
Feature Symbols layer.
