Description:
Abstract:
This GIS data set is a digital general soil association
map of North Carolina developed by the National Cooperative
Soil Survey.  It 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 soil maps for STATSGO are compiled by generalizing
more detailed soil survey maps.  Where more detailed soil survey
maps are not available, data on geology, topography, vegetation,
and climate are assembled, together with Land Remote Sensing
Satellite (LANDSAT) images.  Soils of like areas are studied,
and the probable classification and extent of the soils are
determined.

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

This data set consists of georeferenced digital map data and
computerized attribute data.  The map data are collected in 1-
by 2-degree topographic quadrangle units and merged and
distributed as statewide coverages.  The soil map units are
linked to attributes in the Map Unit Interpretations Record
relational data base which gives the proportionate extent of
the component soils and their properties.
Purpose:
STATSGO depicts information about soil features on
or near the surface of the Earth.  These data are collected as
part of the National Cooperative Soil Survey.

Use_Constraints:
The U.S. Department of Agriculture, Natural Resource
Conservation Service should be acknowledged as the data
source in products derived from these data.

STATSGO was designed primarily for regional, multicounty,
river basin, State, and multistate resource planning,
management, and monitoring.  STATSGO 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, they are responsible
for its appropriate application.  Federal, State, or local
regulatory bodies are not to reassign to the Soil
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 STATSGO data are overlayed with other data layers, such
as land use data, caution must be used in generating
statistics on the co-occurrence of the land use data with the
soil data.  The composition of the STATSGO map unit can be
characterized independently for the land use and for the soil
component, but there are no data on their joint occurrence at
a more detailed level.  Analysis 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 STATSGO 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 approximate minimum area delineated is 625 hectares
(1,544 acres), which is represented on a 1:250,000-scale map
by an area approximately 1 cm by 1 cm (0.4 inch by 0.4 inch).
Linear delineations are not less than 0.5 cm (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 within a delineation.

Digital enlargements 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.

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

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 amendments and are current as of
the date of digitizing.
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 (neatline)
are free of gaps.  The tests of logical consistency are
performed 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 within 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 (i.e., 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
(i.e., adjacent polygons with the same label).  Quadrangles
are edge matched within the state, merged into a statewide
data sets, and then edge matched to adjacent state data sets.
Edge locations do not deviate from centerline to centerline by
more than 0.01 inches.
Completeness_Report:
A map unit is a collection of areas
defined and named the same in terms of their 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 consists of
one to 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.  The STATSGO map unit components are soil series
phases, and their percent composition represents the estimated
areal proportion of each within STATSGO 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 STATSGO 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 limits were established on the classification of
soils and the design and name of map units.  These limits are
outlined in U.S. Department of Agriculture. 1975. Soil
Taxonomy  A basic system of soil classification for making and
interpreting soil surveys. Soil Conserv. Serv., U.S. Dep.

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
that reside with 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 upon their compilation to base
maps that meet National Map Accuracy Standards.  The
difference in positional accuracy between the map unit
boundaries 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, in areas where changes in soils, climate,
topography, and geology occur subtly across a portion 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 inches of their locations on the
digitizing source.  The digital map elements are edge
matched between data sets.  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 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 inches and converted to a
vector format or were manually digitized on a digitizing
tablet with a resolution of at least 0.001 inches.  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 data sets were
edge matched and merged into statewide coverages.  A
detailed and complete edit was performed on all digital
data.

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

The map unit ID uniquely identifies each closed delineation,
map unit.  Each map unit ID is linked to a map unit name.  The
map unit ID is also the key for linking information in the Map
Unit Interpretations Record tables.

The map units described below exist as text files, and can

Map Unit Delineations are described by the Map Unit
Interpretations Record data base.  This attribute data base
gives the proportionate extent of the component soils and the
properties for each soil.  The data base 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 Soil Map Unit Interpretations
Record data base consist of the following relational tables:
codes (data base codes) - stores information on all codes
used in the data base
comp (map unit component) - stores information which will
apply to a specific component of a soil map unit
compyld (component crop yield) - stores crop yield
information for soil map unit components
forest (forest understory) - stores information for plant
cover as forest understory for soil map unit components
interp (interpretation) - stores soil interpretation
ratings (both limitation ratings and suitability
ratings) to soil map unit components
layer (soil layer) - stores characteristics which apply to
soil layers for soil map unit components
mapunit (map unit) - stores information which applies to
all components of a soil map unit
plantcom (plant composition) - stores plant symbols and
percent of plant composition associated with components
of soil map units (CGIA does not have)
plantnm (plant name) - stores the common and scientific
names for plants used in the data base
rsprod (range site production) - stores range site
production information for soil map unit components (CGIA does not have)
taxclass (taxonomic classification) - stores the taxonomic
classification for soils in the data base
windbrk (windbreak) - stores information on recommended
windbreak plants for soil map unit components
wlhabit (wildlife habitat) - stores wildlife habitat
information for soil map unit components
woodland (woodland) - store information on common indicator
trees for soil map unit components
woodmgt (woodland management) - stores woodland management
information for soil map unit components
yldunits (yield units) - stores crop names and the units
used to measure yield
