##$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. |
