Overview of attributes

The geo_net coverage includes polygons that are map units and
open water, and arcs that are contacts, colorboundaries, and
shoreline.
The geo_net.pat INFO file consists of the following items:
GEOCODE--Refers to the type of polygon and is one of the following:
map unit code, "lake", or "island".
AGE--Refers to the age of the map unit and is one of the following:
"HOLOCENE", "HOLOCENE AND LATE WISCONSIN", "LATE WISCONSIN",
"EARLY WISCONSIN", "WISCONSIN", "ILLINOIAN", "PLEISTOCENE",
"QUATERNARY" OR "PRE-QUATERNARY".
MORAINES--A modifier to the map unit indicating that the unit is a
moraine and is one of the following:  "Ground Moraine", "End
Moraine", or "Ground Moraine and end moraine under Lake Michigan."
MAP_UNITS--A description of the soils within the map units (see below).
MODIFIER--Indicates that the map unit is covered with loess more than
2 m thick ("loess mantle") or if the unit is under water ("submerged").
COLOR--An integer value representing a shade pattern in the shadeset
color524.shd used in preparing the plotfile of the map.

The geo_net.aat INFO file consists of the following item:
LTYPE--Refers to the type of arc and is one of the following:
"contact," "shoreline," or "map boundary."
The gla_lin coverage contains lines of linear glacial features.
The gla_lin.aat INFO file consists of the following items:
TYPE--Refers to the type of glacial feature described by the arc
and is one of the following:  "esker," "limit of glacial
advance," "buried moraine," "meltwater channel," "shoreline
deposits," or "map boundary".
MODIFIER--Refers only to ltype = "meltwater channel" and is
either "left bank" or "right bank".
ACCURACY--Refers to accuracy of location of arcs in the gla_lin
coverage and is either "certain" or "inferred".
NAME--Refers to the geounit name (taj) of inferred buried end moraine.
The gla_pnt coverage contains points that represent drumlins,
places where the direction of ice movement is indicated by
striations, or the location of important stratigraphic sections.
The gla_pnt.pat INFO file consists of the following items:
TYPE--Refers to the type of feature shown at the point and is
one of the following:  "drumlin," "direction of ice movement,"
"concentric minor moraines," "glacially fluted landforms," "wind
direction," or the name of important stratigraphic sections.
ANGLE--Refers to the direction of drumlin or ice movement; in
degrees measured clockwise from north.
MRKANGLE--Negative of ANGLE; useful for plotting srmbols in ARCPLOT.
Hydr_lin is a line coverage created after scanning the hydrographic
layer that was used in the original paper map.  It has no attributes.
Topo_lin is a line coverage created after scanning the topographic
layer that was used in the original paper map.  It has no attributes.
Bnd_lin is a line coverage created from 1:2,000,000-scale U.S.
Geological Survey Digital Line Graph coverages (DLG).  It contains
lines representing state boundaries.  The bnd_lin.aat INFO file
contains the following item:  LTYPE--Refers to the type of line
and contains the values: "state boundary", or "map boundary".  The
coverage is annotated with state names along boundaries.

coverages and contains political and administrative boundaries.
Polygons are attributed in the standard DLG coding scheme and the
Federal Information Processing Standards (FIPS).
Rd_lin is a line coverage created from 1:2,000,000-scale DLG coverages.
The coverage contains lines representing roads in the map area.
All DLG attributes have been stripped from the lines except
ROUTE_NUMBER1, ROUTE_NUMBER2, ROUTE_NUMBER3, and ROUTE_NUMBER4.
