Description:
Abstract:
This dataset 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 by using remotely
sensed and other information.
This dataset 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 are large
enough and contrasting enough to substantially 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 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 dataset may be
available from the primary organization listed in the Point of
Contact.

Use_Constraints:
The U.S. Department of Agriculture, Natural Resources Conservation
Service, should be acknowledged as the data source in products
derived from these data.
This dataset 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, the users 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 the users 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 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
these maps do not eliminate the need for onsite sampling, testing, and
detailed study of specific sites for intensive uses. Thus, these data
and 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.

Data_Quality_Information:
Attribute_Accuracy:
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 gap free. The tests of logical
consistency are performed by 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 (such as
adjacent polygons with the same label). Edge locations generally do
not deviate from centerline to centerline by more than 0.01 inch.
The feature edges and descriptive attributes of the quadrangles in the
Oklahoma County Soil Survey match with the quadrangles in the adjacent
Cleveland County Soil Survey, Kingfisher County Soil Survey, and Logan
County Soil Survey. The feature labels do not match. The feature edges,
feature labels and descriptive attributes of the quadrangles in the
Oklahoma County Soil Survey do not match with the quadrangles in the
adjacent Canadian County Soil Survey, Lincoln County Soil Survey, and
Pottawatomie County Soil Survey. The feature labels do not match.
Completeness_Report:
A map unit is a collection of areas defined and named in terms of
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 identified
on the map is a delineation.
Soil scientists identify small areas of soils or miscellaneous
(nonsoil) areas that have properties and behavior substantially
different than the named soils in the surrounding map unit. These
minor components may be indicated as special features. If these small
soils areas have a minimal effect on use and management, or could not be
precisely located, these areas 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
substantially 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 in 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 the proportions
may vary 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 the use and management are the same
or very similar for common uses. Generally these components are
grouped together because some common feature, such as steepness,
stoniness, or flooding, determines the use and management. If two
or more additional map units would serve no useful purpose, the
additional groups may be included in the same unit. Each
delineation has at least one of the major components, and some
may have all components. 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.
Minimum documentation consists of three complete soil profile
descriptions that are collected for each soil added to the explanation,
one additional per 3,000 acres mapped; three 10 observation
transects for each map unit, one additional 10 point transect per
3,000 acres.
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 5 acres.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy of these digital data is based on the
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 the 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 the locations on
the digitizing source. The digital map elements are edge matched
between datasets. 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.

Process_Description:
Oklahoma County, Oklahoma, had a previously published soil
survey, 1969, 1:20,000 scale. A detailed evaluation
found that substantial changes in land use, soil classification,
soil interpretations, and standards and procedures for making soil
surveys, made the previously published Oklahoma County Soil Survey
obsolete. A soil survey update for Oklahoma County was initiated
in 1992 and was completed in 1994. The classification and map unit
names were finalized at the final field review in November 1994.
Field procedures for the second order soil survey included plotting
of soil boundaries determined by field observations and by
interpretation of remotely sensed data. Boundaries were verified
at closely spaced intervals, and the soils in each delineation were
identified by traversing and transecting the landscape. Soil
scientists described and sampled the soils, analyzed samples in
the laboratory, and statistically analyzed the data.

Process_Description:
Field maps were manually compiled to 1:15,840 multiple black
and white photographs. Ratioed film positives (1:12,000)
were produced from the publication negatives (1:15,840).
The soil delineations were inked onto Hulen punch registered
stable-base (4 mil.) annotated mylar overlays by using 1:12,000
orthophotographs as a compilation base map.

Process_Step:
Process_Description:
The annotated mylar overlays were raster scanned by using
A-scan software on an ANAtech Eagle 3640 optical scanner at a
scanning resolution of 0.01 inch. Four control points corresponding
to the four corners of the quadrangles and four interior control
points were used for registration during data collection. The
processing, raster editing, map neatline development, labeling, edge
matching, vector conversion and editing, were completed in LT4X.
The data were exported from LT4X and imported into GRASS Version 4.13.
The data are in North American Datum of 1983. Special soil features
were manually digitized by using GRASS Version 4.13 at a resolution of 0.1
inch. The data were written to a Digital Line Graph (DLG)optional format
with the v.export command. Map compilation and quality control were
performed by soil scientists, cartographers, and cartographic
technicians at the Natural Resources Conservation Service, Oklahoma,
along with staff from Oklahoma State University where the data were
scanned, digitized, and attributed.

version number and date stamp were added and the data were copied to
the data warehouse. The tabular data for the map units and components
were extracted from the data warehouse and reformatted into the soil
data delivery data model, then stored in the Soil Data Mart. The spatial
data were copied to the Soil Data Mart without change.

Process_Description:
The Natural Resources Conservation Service, State Soil Scientist or
delegate, on completion of data-quality verification, determined
that the tabular data should be released for official use. A
selected set of map units and components in the soil survey explanation was
copied to a staging database, and rating values for selected
interpretations were generated. The list of selected interpretations is
stored in the database table named sainterp.

Overview_Description:
Entity_and_Attribute_Overview:
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 these delineations 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. The database documents the data structure and includes
such information as what tables, columns, indexes, and relations
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.
Special features are described in the feature table. The feature
table includes an area symbol, feature label, feature name, and
feature description for each special and ad hoc feature in the survey area.
