- 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 7.5 minute
quadrangle format and include a detailed, field verified inventory
of soils and nonsoil 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.

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

This soil survey contains information that can be applied in
managing farms and wetlands; in selecting sites for roads, ponds,
buildings, and other structures; and in judging the suitability
of tracts of land for farming, industry, and recreation.
This soil survey 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.

- 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 (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 soil survey
area and edge locations generally do not deviate from centerline to
centerline by more than 0.01 inch. The extent of the soil survey
boundary is edge matched to the adjacent SSURGO certified soil
survey boundaries of Prowers and Baca Counties, Colorado. However,
feature labels and soils lines in this survey are not matched to
those of adjacent surveys.
- 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 or more components.
Soil scientists identify small areas of soils or miscellaneous
(nonsoil) 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 may not be indicated on the map.
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, SCS; Agricultural Handbook 436, Soil Taxonomy, Soil Survey
Staff, 1975, USDA, SCS; and all Amendments; Keys to Soil Taxonomy,
Soil Survey Staff, (current issue); National Soil Survey
Handbook, title 430-VI, (current issue).
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 are dominated by a single soil
taxon and similar soils. At least one half of the pedons in each
delineation are of the same soil component so similar to the
named soil that major interpretations are not affected
significantly. 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 are named
for two or more dissimilar components with the dominant component
listed first. They occur in a regularly repeating pattern. The major
components of a complex cannot be mapped separately at a scale of
about 1:24,000. The major components of an association can be
separated at a scale of about 1:24,000. In each delineation of
either 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 do not always occur together in the same
delineation, but are included in the same named map unit because
use and management are the same or similar for common uses. Every
delineation has at least one of the major components and some may
have all of them. The same principles regarding proportion of
inclusions 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.

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
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.

Major fieldwork for this soil survey was done in the peroid of
1962-61. It was determined at that time that the soil map unit
delineations and map unit components were accurate. The
classifications and correlations of map unit names were finalized
in June, 1965. This resulted in the published Soil Survey of Bent
County, Colorado, 1971, at a scale of 1:15,840 (irrigated areas)
and 1:31,680 (other areas).

Ratioed publication positives of the published soil survey were
referenced to manually compile soil delineations onto stable-based
annotated overlays that were punch registered to USGS NAD27 stable-
based orthophotographs. USGS NAD27 topographic quadrangles were also
used as a reference in the compilation process. Compilation was
performed by Kansas State University (KSU) students under the direct
supervision of a Natural Resources Conservation Service (NRCS) soil
scientist. Quality control was performed by the NRCS soil scientist
prior to scanning. The soil delineation overlays were raster scanned
at 400X400 dots per inch using an Ideal FSS4016T full scale scanner.
Four control points corresponding to the four corners of the USGS
topographic quadrangles were used in the data collection. Raster to
vector conversion was done using Scorpion SRV386 software. The
processing, vector editing, labeling, and edge matching were done
using PC ARC/INFO version 3.4D. Special soil features were digitized
in a seperate layer. Digitizing was performed by KSU students under
supervision of a university professor in the Department of Geography.
Quality control was performed by the NRCS soil scientist on check
plots after scanning, labeling, and editing were completed. The soil
line and special feature files were exported to and written to
Arc/Info interchange files.

The digital soils layer was imported into Arc/Info 7.2.1, and
converted from single to double precision. A seamless NAD27 county
coverage was projected to NAD83, and neatlines were then added using a
NAD83 index coverage. The extent of the soil survey boundary was edge
matched to the adjacent SSURGO certified surveys of Baca and Prowers
Counties, Colorado. Quadrangles were edgematched, and neatlines were
checked for accuracy by NRCS Cartographic Technicians. The digital
special features layer was also imported into Arc/Info 7.2.1,
converted from single to double precision, and projected from NAD27 to
NAD83. The soil line and special feature files were exported to and
written to Digital Line Graph optional (DLG-3) format. The data were
imported for verification in Arc/Info 7.2.1, and the data were
reviewed by NRCS Regional Digitizing Center staff in Salina, Kansas,
for adherence to SSURGO standards.

This export was done primarily to meet the data population requirements outlined in National Soil Bulletin 430-5-7. The major changes to the dataset involved population ofAlbedo dry, Component 3D Surface Morphometry, Component Slope Shape, Component Aspect, Component Parent Material, and Horizon Structure for the surface mineral layer only. The Brief Map Unit Description Report was also calculated. All National Interpretations, Department of Homeland Security, and Military Interpretations were included in the export.All obsolete stored interpretations, with the exception of Hydric, in the Component Interpretations table were deleted. Slope shape and slope aspect were determined from DEMs utilizing ArcGIS tools. Where multiple slope shapesand slope aspects were determined for a map unit, thepredominant slope shape, or slope aspect, was entered as the RVfor all components in the map unit. Values for Albedo were populated for components where a taxonomic unit description was available. For many higher taxons (boralfs, cryoboralfs) in the older surveys a representative profile description was not available to assign Albedo. Albedo was left blank for these components.

This 2008 data export contains the following changes and updates from previous versions:
AASHTO Group calculations were run to provide for new Local Roads and Street interpretations.
New irrigation (General, Micro, Sprinkler, & Surface) interpretations were added.
ENG - Hydrologic Soil Group Generator was added to this Export.
Standard Pond Reservoir interpretation was modified.
ENG - Construction Materials; Gravel Source interpretation was modified.
Prime and other Important Farmland classification ratings were reviewed and, where necessary, edited to be more consistent in accordance with NSSH standards.

Map Unit Delineations are closed polygons that may be dominated
by a single soil or nonsoil component plus allowable similar or
dissimilar soils, or they can be geographic mixtures of groups
of soils or soils and nonsoil areas.
The map unit symbol uniquely identifies each closed delineation
map unit. Each symbol is linked to a map unit name. The map unit
symbol is also the key for linking information in the National Soil
Information System tables. The map unit symbols are not carried
within the modified Digital Line Graph file; however, they are made
available in a companion attribute file. The attribute file links
the minor codes in the Digital Line Graph files to the map unit
symbols.
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 a
feature label, feature name, and feature description for each
special and ad hoc feature in the survey area.
