Description:
Abstract:
This dataset consists of general soil association units. The dataset was
developed by the National Cooperative Soil Survey and supersedes
the State Soil Geographic (STATSGO) dataset published in 1994.
This dataset consists of a broad based inventory of soils and nonsoil areas
that occur in a repeatable pattern on the landscape and that can
be cartographically shown at the scale mapped. The dataset was
created by generalizing more detailed soil survey maps. Where more
detailed soil survey maps were not available, data on geology,
topography, vegetation, and climate were assembled, together with
Land Remote Sensing Satellite (LANDSAT) images. Soils of like areas
were studied, and the probable classification and extent of the soils
were determined.

Map unit composition was determined by transecting or sampling areas
on the more detailed maps and expanding the data statistically to
characterize the whole map unit.

This dataset consists of georeferenced vector digital data and
tabular digital data. The map data were collected in 1- by 2-degree
topographic quadrangle units and merged into a seamless national
dataset. It is distributed in state/territory and national extents.
The soil map units are linked to attributes in the National Soil
Information System database that gives the proportionate extent of
the component soils and properties.
Purpose:
These data provide information about soil features on or near the
surface of the Earth. Data were collected as part of the National
Cooperative Soil Survey. These data are intended for geographic
display and analysis at the state, regional, and national level.
These data should be displayed and analyzed at scales appropriate for
1:250,000-scale data.

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. Hardcopies utilizing these data shall
clearly indicate the source used. User agrees not to misrepresent these
data, nor to imply that changes made were approved by the Natural
Resources Conservation Service.

The Digital General Soil Map of U.S. was designed primarily for
regional, multicounty, river basin, State, and multistate resource
planning, management, and monitoring. Data are not detailed enough
to make interpretations at a county level. This soil survey product
is not designed for use as a primary regulatory tool in permitting
or citing decisions, but may be used as a reference source. The use
of these data is not restricted and may be interpreted by organizations,
agencies, units of government, or others; however, 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 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.

When data from the Digital General Soil Map of U.S. are overlayed
with other data layers, such as land-use data, caution must be
used in generating statistics on the co-occurence of the land-use
data with the soil data. The composition of the soil map unit can
be characterized independently for the land use and for the soil
component, but there are no data on the joint occurrence at a
more detailed level. Analyses of the overlayed data should be on a
map polygon basis.

Additional political, watershed, or other boundaries may be
intersected with the soil data. Although the composition of each
political and watershed unit may be described in terms of the
soil map units, information is not available to assign the
components to the boundary units with full accuracy. As with the
land-use categories, the analysis should be restricted to the
classified components.

The estimated minimum area delineated is 625 hectares
(1,544 acres), which is represented on a 1:250,000-scale map by
an area about 1 centimeter by 1 centimeter (0.4 inch by 0.4 inch). Linear
delineations are not less than 0.5 centimeter (0.2 inch) in width. The
number of delineations per 1:250,000 quadrangle typically is 100
to 200, but may range up to 400. Delineations depict the dominant
soils making up the landscape. Other dissimilar soils, too small
to be delineated, are present in a delineation.

Digital enlargements of these data to scales greater than at
which 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 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.

Data values for some data elements may be incomplete or missing.
Where data are unavailable, a mask should be used to exclude the
area from analysis.

The spatial and tabular data used to create this product are
periodically updated. Data are versioned, and users are responsible
for obtaining the latest version of the product.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
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 amendments and are current as of
the date of digitizing.
Logical_Consistency_Report:
Certain node/geometry and topology (GT)-polygon/chain
relations 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 (neatline) are free of gaps.
The tests of logical consistency are performed by using vendor
software. The neatline is generated by connecting the explicitly
entered four corners of the digital file. All data outside the
enclosed region are ignored and all data crossing these
geographically straight lines are clipped at the neatline. Data
in a specified tolerance of the neatline are snapped to the
neatline. Neatline straightening aligns the digitized edges of
the digital data with the generated neatline (that is with the
longitude/latitude lines in geographic coordinates). 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 (that is adjacent polygons with the same label). Quadrangles
are edge matched in the state, merged into a statewide datasets, 
and then edge matched to adjacent state datasets. Edge
locations do not deviate from centerline to centerline by more
than 0.01 inch.
Completeness_Report:
A map unit is a collection of areas defined and named the same
in terms of the soil and/or nonsoil areas. Each map unit differs
in some respect from all others in a survey area and is uniquely
identified. Each individual area is a delineation. Each map unit
in the Digital General Soil Map of U.S. consists of one to more
than 21 components.

In those few areas where detailed maps did not exist,
reconnaissance soil surveys were combined with data on geology,
topography, vegetation, climate, and remote sensing images to
delineate map units and estimate the percentages of components.
Map unit components in this product are soil series phases, and
the percentage composition represents the estimated areal proportion
of each in a map unit. The composition for a map unit is
generalized to represent the statewide extent of that map unit
and not the extent of any single map unit delineation. These
specifications provide a nationally consistent representation of
the associated attribute data.

The actual composition and interpretive purity of the map unit
delineations were based on statistical analysis of transect data.
The composition was largely determined by measuring transects on
detailed soil survey maps. The number of transects used was
proportional to the relative size, number, and complexity of the
delineations. The combined data on the length of the map units
crossed by the transects were used to determine the percentages
of the different soil and nonsoil areas in each map unit.

Specific National Cooperative Soil Survey Standards and
procedures were used in the classification of soils, design, and
name of map units. These standards are outlined in: 

U.S. Department of Agriculture, Natural Resources Conservation Service, 1999, Soil Taxonomy--A basic system of soil classification for making and interpreting soil surveys (2nd ed.).

U.S. Department of Agriculture, Natural Resources Conservation Service, 2003, Keys to Soil Taxonomy (9th ed.).

U.S. Department of Agriculture, Natural Resources Conservation Service, 2007, National Soil Survey Handbook, title 430-V.

U.S. Department of Agriculture, Natural Resources Conservation Service, 1994. State Soil Geographic (STATSGO) Data Base: Data-use information, Soil Conservation Service.

Adherence to National Cooperative Soil Survey standards and
procedures is based on peer review, quality control, and quality
assurance. Quality control is outlined in documents in possession of
 the Natural Resources Conservation Service state soil scientist.
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. The difference in positional accuracy between
the map unit boundaries in the field and the digitized
map locations is unknown. The locational acuracy of soil
delineations on the ground varies with the transition
between map units.

For example, in areas where changes in soils, climate,
topography, and geology occur subtly across a part of a
state, the transition between soil map unit boundaries will
be gradual. Where these features change abruptly, such as
from an area of foothills to a lake plain, the transition
will be very narrow. Soil delineation boundaries 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 state boundary are
matched against the data for the adjacent state. Edge
locations generally do not deviate from centerline to
centerline by more than 0.01 inch.

Soil map unit lines and symbols were drafted in red pencil
on a mylar overlay that was punch registered to fit the mylar
U.S. Geological Survey (USGS) 1:250,000-scale topographic 
quadrangle. A detailed and complete edit was performed on 
all overlays before digitizing.
The soil delineation overlays were raster scanned at a
scanning resolution of at least 0.01 inch and converted to
a vector format or were manually digitized on a digitizing
tablet with a resolution of at least 0.001 inch. Four
control points corresponding to the four corners of the
quadrangles were used for registration during data collection.
The control points were either explicitly entered or developed
by the software. The datasets were edge matched and merged
into statewide coverages. A detailed and complete edit was

Overview_Description:
Entity_and_Attribute_Overview:
Map Unit Delineations are closed polygons that are geographic
mixtures of groups of soils or soils and nonsoil areas.

The map unit key uniquely identifies each closed map unit
delineation. Each map unit key is linked to a map unit symbol
and a map unit name. The map unit key also is the key for linking
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 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
distribution metadata. The database records the criteria used in the set
of distributed data.
