  Description:

    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.

    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.

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 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 Soil Survey of Athens County, Ohio is edge matched to adjacent SSURGO

    certified Soil Surveys Morgan and Perry Counties, Ohio.  The soil survey

    area boundaries match.

  Completeness_Report:

    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 a 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 many

    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 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.

 

    Minimum documentation consists of three complete soil profile

    descriptions that are collected for each soil added to the legend,

    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 2.0 acres.

  Positional_Accuracy:

    Horizontal_Positional_Accuracy:

      Horizontal_Positional_Accuracy_Report:

        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.

        Field procedures for the second order soil survey

        included plotting of soil boundaries determined by field observations

        in conjunction with aerial photo interpretation. 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 analyzed the data. The classification and map

        unit names were finalized at the final correlation conference in 1981

        and signed in 1981. The published soil survey report was released in

        1985.

      Process_Description:

        The data were sent to the U.S. Department of

        Agriculture, Natural Resources Conservation Service, Wisconsin

        Digitizing Unit, Madison, Wisconsin (WIDU). The annotated soil

        delineation overlays were sent to Midwest Graphics, Kenosha, Wisconsin

        for raster scanning at 250 dpi on an Intergraph Anatach scanner in

        rlc format.  The raster scanned data were imported into LT4X Version

        4.1.1 maps. Once all the scanned soil lines were added to the maps, a

        county border was added.  The special soil features were manually

        digitized from the annotated soil delineations in LT4X at a resolution

        of 0.01 inch. The raster editing, labeling, edge matching, and vector

        conversion were done in LT4X.  Check plots of the soils and special soil

        features were reviewed by a soil scientist and cartographic staff at the

        WIDU. A ten percent quality assurance review was done of the soils and

        special features by a MLRA R-11 Data Quality Specialist.

        The soils and special soil features data were run through a series

        of LT4X macros for correctness and completeness.  These macros smoothed

        and thinned out linework, added nodes for every 3000 vertices, added

        corner nodes and snapped nodes across the neatlines.  The soils and

        special soil features data were then exported as Digital Line Graph-3

        Optional format files (DLGs) in LT4X.  The DLGs were evaluated with

        the modified Oct. 1998 ARC/INFO SSURGO Evaluation AMLs provided by

        U.S. Department of Agriculture, Natural Resources Conservation Service,

        National Cartography and Geospatial Center, Fort Worth, Texas (NCGC).

        Once in Arc, the official border, provided by Ohio Department

        of Natural Resources, was edited to the survey.  Upon successful

        completion of the SSURGO Evaluation and map unit verification with NASIS

        tabular data the SSURGO spatial data were processed with the October 2003

        archiving AMLs provided by NCGC.  The certified data were ftped to NCGC

        for archival and distribution.

  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 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.

 

      Special features are described in the feature table.  It includes an

      area symbol, feature label, feature name, and feature description for

      each special and ad hoc feature in the survey area.
