- Abstract:
-
This data set is a digital soil survey and generally is the most
detailed level of soil geographic data developed by the National
Cooperative Soil Survey. The information was prepared by digitizing
maps, by compiling information onto a planimetric correct base
and digitizing, or by revising digitized maps using remotely
sensed and other information.
This data set consists of georeferenced digital map data and
computerized attribute data. The map data are in a soil survey area
extent format and include a detailed, field verified inventory
of soils and miscellaneous areas that normally occur in a repeatable
pattern on the landscape and that can be cartographically shown at
the scale mapped. A special soil features layer (point and line
features) is optional. This layer displays the location of features
too small to delineate at the mapping scale, but they are large
enough and contrasting enough to significantly influence use and
management. The soil map units are linked to attributes in the
National Soil Information System relational database, which gives
the proportionate extent of the component soils and their properties.
- Purpose:
-
SSURGO depicts information about the kinds and distribution of
soils on the landscape. The soil map and data used in the SSURGO
product were prepared by soil scientists as part of the National
Cooperative Soil Survey.
- Supplemental_Information:
-
Digital versions of hydrography, cultural features, and other
associated layers that are not part of the SSURGO data set may be
available from the primary organization listed in the Point of
Contact.

The U.S. Department of Agriculture, Natural Resources Conservation
Service, should be acknowledged as the data source in products
derived from these data.
This data set is not designed for use as a primary regulatory tool
in permitting or citing decisions, but may be used as a reference
source. This is public information and may be interpreted by
organizations, agencies, units of government, or others based on
needs; however, they are responsible for the appropriate
application. Federal, State, or local regulatory bodies are not to
reassign to the Natural Resources Conservation Service any
authority for the decisions that they make. The Natural Resources
Conservation Service will not perform any evaluations of these maps
for purposes related solely to State or local regulatory programs.
Photographic or digital enlargement of these maps to scales greater
than at which they were originally mapped can cause misinterpretation
of the data. If enlarged, maps do not show the small areas of
contrasting soils that could have been shown at a larger scale. The
depicted soil boundaries, interpretations, and analysis derived from
them do not eliminate the need for onsite sampling, testing, and
detailed study of specific sites for intensive uses. Thus, these data
and their interpretations are intended for planning purposes only.
Digital data files are periodically updated. Files are dated, and
users are responsible for obtaining the latest version of the data.

- Attribute_Accuracy_Report:
-
Attribute accuracy is tested by manual
comparison of the source with hard copy plots and/or symbolized
display of the map data on an interactive computer graphic system.
Selected attributes that cannot be visually verified on plots or
on screen are interactively queried and verified on screen. In
addition, the attributes are tested against a master set of valid
attributes. All attribute data conform to the attribute codes in
the signed classification and correlation document and amendment(s).
- Logical_Consistency_Report:
-
Certain node/geometry and topology GT- polygon/chain relationships
are collected or generated to satisfy topological requirements
(the GT-polygon corresponds to the soil delineation). Some of these
requirements include: chains must begin and end at nodes, chains
must connect to each other at nodes, chains do not extend through
nodes, left and right GT-polygons are defined for each chain
element and are consistent throughout, and the chains representing
the limits of the file are free of gaps. The tests of logical
consistency are performed using vendor software. All internal
polygons are tested for closure with vendor software and are checked
on hard copy plots. All data are checked for common soil lines (i.e.,
adjacent polygons with the same label). Edge locations generally do
not deviate from centerline to centerline by more than 0.01 inch.
The boundary of this survey is matched to the adjacent SSURGO
certified surveys of Union County, Illinois, Pulaski County, Illinois,
Ballard and McCracken Counties, Kentucky, Cape Girardeau County,
Missouri, Mississippi County, Missouri and Scott County, Missouri.
Feature edges match those of the Union County and Pulaski County,
Illinois surveys only. Most feature labels match those of the Union
County and Pulaski County, Illinois surveys. Descriptive attributes
(tabular information about the polygons and line segments) were
developed specifically for each survey area. Although most don't
match exactly, the descriptive attributes of most polygon and line
segments in this survey are nearly the same as adjacent ones in Union
County and Pulaski County, Illinois.

A map unit is a collection of areas defined and named in terms of
their soil components or miscellaneous areas or both. Each map
unit differs in some respect from all others in a survey area and
each map unit has a symbol that uniquely identifies the map unit
on a soil map. Each individual area, point, or line so identified
on the map is a delineation.
Soil Scientists identify small areas of soils or miscellaneous areas
that have properties and behavior significantly different than the
named soils in the surrounding map unit. These minor components
may be indicated as special features. If they have a minimal effect
on use and management, or could not be precisely located, they may
not be indicated on the map.
A map unit has specified kinds of soils or miscellaneous areas
(map unit components), each with a designated range in
proportionate extent. Map units include one or more kinds of soil
or miscellaneous area. Miscellaneous areas are areas that have little
or no recognizable soil.
Specific National Cooperative Soil Survey standards and procedures
were used in the classification of soils, design and name of map
units, and location of special soil features. These standards are
outlined in Agricultural Handbook 18, Soil Survey Manual, 1993,
USDA, NRCS; Agricultural Handbook 436, Soil Taxonomy, 1995,
USDA, NRCS; and all Amendments; Keys to Soil Taxonomy,
(current issue) USDA, NRCS; National Soil Survey
Handbook, title 430-VI,(current issue) USDA, NRCS.
The actual composition and interpretive purity of the map unit
delineations were based on data collected by scientists during
the course of preparing the soil maps. Adherence to National
Cooperative Soil Survey standards and procedures is based on
peer review, quality control, and quality assurance. Quality
control is outlined in the memorandum of understanding for the
soil survey area and in documents that reside with the Natural
Resources Conservation Service state soil scientist. Four kinds
of map units are used in soil surveys: consociations, complexes,
associations, and undifferentiated groups.
Consociations - Consociations are named for the dominant soil.
In a consociation, delineated areas use a single name from the
dominant component in the map unit. Dissimilar components are
minor in extent. The soil component in a consociation may be
identified at any taxonomic level. Soil series is the lowest
taxonomic level. A consociation that is named as a miscellaneous
area is dominantly that kind of area and minor components do not
significantly affect the use of the map unit. The total amount of
dissimilar inclusions of other components in a map unit generally
does not exceed about 15 percent if limiting and 25 percent if
nonlimiting. A single component of a dissimilar limiting inclusion
generally does not exceed 10 percent if very contrasting.
Complexes and associations - Complexes and associations consist
of two or more dissimilar components that occur in a regularly
repeating pattern. The total amount of other dissimilar components
is minor extent. The following arbitrary rule determines whether
complex or association is used in the name. The major components
of an association can be separated at the scale of mapping. In
either case, because the major components are sufficiently different
in morphology or behavior, the map unit cannot be called a
consociation. In each delineation of a complex or an association,
each major component is normally present though their proportions
may vary appreciably from one delineation to another. The total
amount of inclusions in a map unit that are dissimilar to any of
the major components does not exceed 15 percent if limiting and
25 percent if nonlimiting. A single kind of dissimilar limiting
inclusion usually does not exceed 10 percent.
Undifferentiated groups - Undifferentiated groups consist of two
or more components that are not consistently associated
geographically and, therefore, do not always occur together in
the same map delineation. These components are included in the
same named map unit because their use and management are the same
or very similar for common uses. Generally they are grouped together
because some common feature, such as steepness, stoniness, or
flooding, determines their use and management. If two or more
additional map units would serve no useful purpose, they may be
included in the same unit. Each delineation has at least one of the
major components, and some may have all of them. The same principles
regarding the proportion of minor components that apply to
consociations also apply to undifferentiated groups. The same
principles regarding proportion of inclusion apply to
undifferentiated groups as to consociations.
This survey is a subset of MLRAs 115B, 120, 131 and 134. Profile
descriptions and transects from elsewhere in each MLRA supplement
documentation from within the subset. Minimum documentation consists
of three or more complete soil profile descriptions for each series
added to the legend. In addition, transects were recorded as needed
to support correlation decisions. The number of stops in each
transect was dependent on the size of the particular map unit and
the soil properties involved.
A defined standard or level of confidence in the interpretive
purity of the map unit delineations is attained by adjusting the
kind and intensity of field investigations. Field investigations
and data collection are carried out in sufficient detail to name
map units and to identify accurately and consistently areas of
about 2 acres.

The accuracy of these digital data is based upon their
compilation to base maps that meet National Map
Accuracy Standards at a scale of 1 inch equals 1,000
feet. The difference in positional accuracy between the
soil boundaries and special soil features locations in the
field and their digitized map locations is unknown. The
locational accuracy of soil delineations on the ground varies
with the transition between map units.
For example, on long gently sloping landscapes the transition
occurs gradually over many feet. Where landscapes change
abruptly from steep to level, the transition will be very
narrow. Soil delineation boundaries and special soil features
generally were digitized within 0.01 inch of their locations on
the digitizing source. The digital map elements are edge matched
between data sets. The data along each quadrangle edge are
matched against the data for the adjacent quadrangle. Edge
locations generally do not deviate from centerline to centerline
by more than 0.01 inch.

The Soil Survey of Pulaski and Alexander Counties, Illinois
was previously published in 1968, at 1:15,840 scale. A detailed
evaluation found changes in land use, soil classification, soil
interpretations, and standards and procedures for making soil
surveys made the 1968 survey obsolete.

- Process_Description:
-
Field investigations were completed as part of the Major Land
Resource Area (MLRA) soil survey update. Changes in the soil
boundaries were noted on the atlas sheets. A recorrelation of
the 1968 soil survey classification and map unit names was
finalized in May, 2002.

Ratioed film positives were produced at a scale of 1:12,000 from
the composite publication film positives. These positives were
used to manually recompile the soil delineations onto 4-mil film
overlays registered to 3.75 minute orthophoto quadrangle base
maps. The 7.5 minute topographic quadrangles were plotted at
1:12,000 scale and used as a reference during recompilation.
Slope class maps, derived from Digital Elevation Models (DEMs),
were used as a reference during recompilation. The edited atlas
sheets were also used during recompilation. Compilation and
quality control were performed by soil scientists and GIS
personnel of the Illinois Natural Resources Conservation Service
(NRCS). Source materials for 15 quarter quadrangles were sent to
the NRCS Regional Digitizing Unit in Salina, Kansas for scanning
and digitizing. Atlas sheets for the remaining 20 quarter
quadrangles, located in large bottomland areas, were scanned,
digitized and labeled by the Carbondale MLRA Office. The
resulting coverages were submitted to the Kansas Digitizing Unit
for final editing and SSURGO certification.

The annotated overlays submitted to the Kansas Digitizing Unit
were sent to Midwest Graphics in Kenosha, Wisconsin. The overlays
were scanned on an Anatech Eagle 4050 scanner at a resolution of
300 dpi. Four control points corresponding to the four corners of
each 3.75 minute quadrangle were used for registration during
data scanning and editing. ARC/INFO version 8.3 and ArcGIS version
8.3 were used to import scan files, edit raster maps, thin and
vectorize. Vector coverages were built for polygon topology.
Quadrangle neatlines were dissolved, and node to node joins were
performed to produce a seamless survey-wide soil coverage. Map
units were labeled on-screen. Coverages of the areas digitized by
the Carbondale MLRA office and the Kansas Digitizing Unit were
joined. Custom AMLs were operated for error identification. The
extent of the soil survey boundary was matched to the adjacent
SSURGO certified soil surveys of Union County, Illinois and Cape
Girardeau, Mississippi and Scott Counties, Missouri. 3.75 minute
digital orthophoto quadrangles were used as a reference during
digitizing and quality control review. Editing was completed by
cartographic staff at the Kansas Digitizing Unit. For quality
control, a 100 percent pen plot review of the soils was done by
the Carbondale, Illinois MLRA staff. A ten percent quality
assurance review was done by a senior soil scientist at the MLRA
Office in Indianapolis, Indiana.

Map Unit Delineations are closed polygons that may be dominated
by a single soil or miscellaneous area component plus allowable
similar or dissimilar soils, or they can be geographic mixtures
of groups of soils or soils and miscellaneous areas.
The map unit symbol uniquely identifies each closed map unit
delineation. Each symbol corresponds to a map unit name. The map
unit key is used to link to information in the National Soil
Information System tables.
Map Unit Delineations are described by the National Soil
Information System database. This attribute database gives the
proportionate extent of the component soils and the properties for
each soil. The database contains both estimated and measured data
on the physical and chemical soil properties and soil
interpretations for engineering, water management, recreation,
agronomic, woodland, range, and wildlife uses of the soil.
The National Soil Information System database contains static
metadata. It documents the data structure and includes such
information as what tables, columns, indexes, and relationships
are defined as well as a variety of attributes of each of these
database objects. Attributes include table and column
descriptions and detailed domain information.
The National Soil Information System database also contains a
distribution metadata. It records the criteria used for selecting
map units and components for inclusion in the set of distributed
data.
