  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.

  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.
    Feature edges in this soil survey are not matched to those in George
    County, Mississippi, and Jackson County, Mississippi, soil surveys.
    Feature labels do not 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 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 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.

    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 5 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.

      Process_Description:
        Mobile County, Alabama, had a previously
        published soil survey, 1964, at scale of 1:20000. A detailed
        evaluation of this survey showed that the soil delineations
        and map unit components were accurate.

      Process_Description:
        Soil map unit deleineations and special soil features were 
        manually compiled from the ratioed film positives to stable base 
        overlays registered to orthophotographs at 1:12000 scale by Kari 
        K. Cartographic Services, Warrenton, Oregon. Quality control 
        compilation was done by the NRCS state office in Auburn, AL. 
        Overlays were scanned by Midwest Graphics, Milwaukee, WI, with an 
        Intergraph scanner at 300 dpi resolution. Digitizing was done by 
        Missouri NRCS Digitizing Unit staff. Raster editing and vector 
        conversion were done in R2V Able Software. The vector files were 
        translated to dxf format and imported into Arc/Info 7.2.1. Arc 
        Macro Language programs were used to project, attribute, edge 
        match, and error check the data in Arc/Info. Check plots of each 
        quadrangle were compared to the scanned source materials for 
        accuracy. Errors in the source material were reviewed and 
        corrected by NRCS personnel in Alabama. These corrections were 
        incorporated into the digital data. Special features were manually 
        digitized in Arc/Info. Edits were made in Arc/Edit. The boundary 
        from the statewide digital county boundary file was placed in the 
        spatial data along the surveys western and southern boundary and 
        in the Freemanville NW, Freemanville SW, McCullough SW 
        Quadrangles, and portions of the McCullough NW and Walnut Hill NW 
        Quadrangles.

      Process_Description:
        The National Soil Information System data base was developed by 
        Natural Resources Conservation Service soil scientists according 
        to national standards. The soils data contained in this SSURGO 
        download represents the survey area at the time of final 
        correlation. The official data for program purposes is contained 
        in a dynamic database that is maintained at the local NRCS field 
        office. Interpretations are not stored in NASIS; they are 
        generated from the soils data stored in NASIS. The interpretations 
        included in this SSURGO download were generated from the soils 
        data included with this download. Interpretations generated at 
        another time may not match the included interpretations. For 
        example, the soil interpretations produced from this data set may 
        not match the interpretations in the published soil survey of 
        Clarke, Escambia and Monroe, Counties, Alabama. Most of the rules, 
        evaluations, and properties used to generate NASIS interpretations 
        are controlled by the NRCS, National Soil Survey Center, in 
        Lincoln, Nebraska. Future modifications to these rules, 
        evaluations, or properties could result in different 
        interpretations than those in this download. Estimates of soil 
        properties are based on field examinations, on laboratory tests of 
        samples from the survey area, and on laboratory tests of samples 
        of similar soils in nearby areas. These estimated soil properties 
        include the range of grain-size distribution and Atterberg limits, 
        the engineering classification, and the physical and chemical 
        properties of the major layers of each soil. Some additional soil 
        properties (such as percent sand and silt) are calculated from 
        algorithms within NASIS.

  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.
