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 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.

Other_Citation_Details:: 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.

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 (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 quadrangles in this survey area have been edge matched to the quadrangles in Custer County and Fallon County soil survey areas.

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.

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 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_Step:

Process_Description:: Field procedures for the second order soil survey included plotting of soil boundaries determined by field observation and by interpretation of remotely sensed data. 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 sampled the soils, analyzed samples in the laboratory, and statistically analyzed the data. The classification and map unit names were finalized at the final correlation in March 1992, last amended April, 1996
Source_Used_Citation_Abbreviation: NRCS1
Process_Date: 1996

Process_Step:

Process_Description:: Map compilation was initiated by soil survey staff by transferring soil delineations, labels, and special features from the field sheets to the quad centered 1/3 quad format imagery. This was accomplished by overlaying the quad centered imagery with the field sheets, adjusting the images, and transferring the data.
Source_Used_Citation_Abbreviation: NRCS1, NRCS2
Process_Date: 1992

Process_Step:

Process_Description:: The final compilation procedure was to transfer the soils layer to an annotated overlay. This was accomplished by adjusting the quad centered imagery to their corresponding 7.5 minute topographic quadrangle and transferring the soils and special features to the punch registered to stable-base overlays for scanning.
Source_Used_Citation_Abbreviation: NRCS2, USGS1, NRCS3
Process_Date: 1996

Process_Step:

Process_Description:: The soils layer was digitally captured from the annotated overlays by the NRCS Digitizing Unit in Bozeman, Montana, on a LDS4000 scanner at 300dpi. The soils data were processed using LtPlus Ver. 4.02 by the staff at the Montana Digitizing Unit. The special features were digitized using GRASS 4.12. The LtPlus files were imported to LT4X Version 4.02, edge matched and exported to Grass 4.13. The soils and special features were exported to DLG-3 optional format using the command 'v.export'. The DLGs were reviewed by the certification staff at the Digitizing Unit in Bozeman, Montana using ARC/INFO Version 7.0.4. Common soil delineations, extra vertices and nodes were deleted using ARCEDIT. New DLG-3's were written. The data were forwarded to the National Cartography and Geospatial Center in Fort Worth, Texas, for archiving and distribution.

Process_Date: 1998

Process_Step:

Process_Description:: The National Soil Information System data base was developed by Natural Resources Conservation Service soil scientists according to national standards.
Source_Used_Citation_Abbreviation: NRCS1
Process_Date: 2002

Process_Step:

Process_Description:: Soil scientists discovered a raster scanning error on quadrangle named Pocochichee Butte. The annotated overlay for Pocochichee Butte was rescanned on an Anatek Eagle 4050 scanner at Midwest Graphics in Kenosha, Wisconsin at 300 dots per inch. Four control points corresponding to the four corners of the 7.5 minute quadrangle were used during data collection in LT4X, Version 4.11. Cartographic technicians at the Montana Digitizing Unit developed and maintained the data in North American Datum of 1927. Vector editing, labeling, and edge matching were accomplished. DLG-3 optional files were written with export SSURGO_area option in LT4X 4.11. The data were forwarded to certification staff at the Montana Digitizing Unit for further evaluation routines.
Source_Used_Citation_Abbreviation: NRCS3, NRCS4, NRCS5, USGS1
Process_Date: 2001

Process_Step:

Process_Description:: The online SSURGO data and revised DLG-3 files for Pocochichee Butte were imported to ARC/INFO, Version 7.2.1 at the Natural Resources Conservation Service, Montana Digitizing Unit. The data were processed through revised evaluation program macros dated October 1998. Soils information for Pocochichee Butte Quadrangle was replaced by the revised data of 2000. ARCEDIT was used to correct a polygon label from W to M-W on the Ekalaka Quadrangle. Minor codes were renamed to link spatial data map unit labels to the National Soil Information System data base.
Source_Used_Citation_Abbreviation: NRCS4, NRCS5
Process_Date: 2002

Process_Step:

Process_Description:: Digital orthophoto quarter quadrangle (DOQQ) images were appended to a county wide image for Carter County in ARC/INFO 8.0 by a GIS specialist on staff at the Natural Resources Conservation Service, Montana State Office. The county wide orthophoto image was then processed through MrSID compression software. The compressed county wide image was then forwarded to soil scientists at the state office.

Process_Step:

Process_Description:: County wide SHAPE files of the 2002 SSURGO data for area and special features were imported to ARCMAP 8.0 by soil scientists at the Natural Resources Conservation Service State Office in Bozeman, Montana. SHAPE files were projected to Universal Transverse Mercator (UTM), zone 13, North American Datum of 1983. EDIT TOOLS were used to adjust soil delineations along riparian areas, and water areas in order to fit current imagery. All special soil linear features were removed because they were accounted for in area feature map units. Small water bodies less than 5 acres were considered for conversion to perennial water (WAT) points, and were added to the special soil point features. Compilation review of the county wide SHAPE files were completed by soil scientists at the state office in Bozeman, Montana. The modified SHAPE files were delivered to certification staff at the Montana Digitizing Unit for evaluation.

Process_Step:

Process_Description:: The modified SHAPE files were imported to county wide coverages in ARC/INFO 8.1 by cartographic technicians on staff at the Montana Digitizing Unit. NAD83, 7.5 minute quadrangle grid was used to intersect the coverages. Quadrangles were then reselected for the Carter County survey area. Quality control routines were completed on all quadrangles for area and special point features. ARCEDIT was used to correct label errors and node mismatches. Digital Line Graph Optional, (DLG-3) files were written. The DLG-3 files were imported to ARC/INFO 7.21 and were processed through revised evaluation program macros dated October 1998. New DLG-3 files were written. The data were forwarded to the National Cartography and Geospatial Center in Ft. Worth, Texas for archiving and Distribution.

Overview_Description:

Entity_and_Attribute_Overview:

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.
