Overview of attributes

Because these data were created in Arc/Info, polygons are
described by tables fitting the pattern cover.pat (here and
after, "cover" refers to the name of the Arc/Info coverage).
These contain the general attributes AREA, PERIMETER, cover#,
and cover-ID.  Likewise, lines are described by tables named
cover.aat, and contain topological as well as general attributes
FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, cover#, and cover-ID.
Because these data were created using Alacarte, the feature
attribute tables also include the attributes LTYPE for lines
and PTYPE for points and polygons, as well as SEL, which is
used internally by Alacarte to mark features that are selected,
and SYMB, which is used internally by Alacarte to symbolize
the features for display.  Additional attributes that contain
scientific information may also be present, and are described
in detail here.
