Landslides in Panzós quadrangle, Guatemala

Description This cover contains the outlines of landslides formed during Hurricane Mitch in October - November 1998. Jeffrey Coe and Robert Bucknam mapped the landslides and related effects in and adjacent to downstream drainages. Most landslides were mapped using
Originators Bucknam, Robert C.; Coe, Jeffrey A.; Mota, Manuel Antonio; Godt, Jonathan W.; Tarr, Arthur C.; Bradley, Lee-Ann; Rafferty, Sharon A.; Hancock, Dean; Dart, Richard L.; and Johnson, Margo L.

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.
