Citation_Information Originator: U.S. Department of Agriculture, Natural Resources Conservation Service Publication Date: 1994 Title: National Map Unit Interpretation Record (MUIR) Database Publication Information Publication Place: Fort Worth, Texas Publisher: U.S. Department of Agriculture, Natural Resources Conservation Service Description Abstract: This data set is a collection of soil and soil-related properties, interpretations, and performance data for a soil survey area and its map units, map unit components, and component layers. This data set has been developed by the National Cooperative Soil Survey and is a dynamic soil information and database. Information contained within the MUIR database have been reviewed and certified in accordance with National Cooperative Soil Survey data quality standards. MUIR data contains about 88 estimated soil physical and chemical properties, interpretations, and performance data. Examples are available water capacity; soil reaction; soil erodibility factors (K, Kf, and T); hydric soil ratings; ponding, flooding, water table depth, and duration; bedrock; interpretations for sanitary facilities, building site development, engineering, cropland, woodland, and recreational development; and yields for common crops, site indices of common trees, and potential production of rangeland plants. Purpose: MUIR 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. Time Period of Content Single Date/Time Calendar Date: 1994 Currentness Reference: publication date Status Progress: Approximately 80 percent of the United States, by county. Maintenance and Update Frequency: Published yearly. Spatial Domain Bounding Coordinates The bounds of the MUIR data are those of individual soil survey areas. In many cases, the soil survey area boundaries correspond with the county boundaries. In other cases, the soil survey areas may comprise only a portion of a county or may comprise an area larger than a single county (e.g. 2 or more counties). A few soil survey areas correspond to some other geopolitical boundary, such as a National Forest or a National Park.

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, 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. MUIR data should be used in conjuntion with soil survey maps. The soil survey maps indicate the geographic location and extent of the soil map units within the soil survey area. Mapping scales generally range from 1:12000 to 1:31680. The maps meet or exceed the national NRCS mapping specifications. MUIR data are intended to be used by landowners, county and local governments, and other natural resource managers for basic land use planning. It is not intended to be used for site-specific land use suitability determinations, such as approval, siting, and sizing of septic tank absorption fields. 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 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. Some of the data elements in the MUIR may contain incomplete or missing data. In some cases, the soil property represented by the data element is not appropriate to the soil survey areas, and has, therefore, been intentially left blank (e.g.gypsuml and gypsumh). In other situations, the data are actively being edited and are incomplete, as of the data of the data download for the National MUIR database. These data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data.

Attribute_Accuracy Attribute Accuracy Report: Attribute accuracy is tested by automated data validation procedures, including data type, data length, data range, key data field, and null key fields. In addition, soil scientists performed manual comparison with the official published soil survey. 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 download from the State Soil Survey Database, contained within each state. Logical Consistency Report: none Completeness Report: Most MUIR data exist in the database as a range of soil properties, depicting the range for the soil survey area. Data are obtained from a combination of field observations, site descriptions and transects, and laboratory analyses. Some of the data elements in the MUIR may contain incomplete or missing data. In some cases, the soil property represented by the data element is not appropriate to the soil survey areas, and has, therefore, been intentially left blank (e.g.gypsuml and gypsumh). In other situations, the data are actively being edited and are incomplete, as of the date that the data was downloaded to the National MUIR database. In making the soil survey, soil scientists observed landforms and landscape features, such as steepness, length, and shape of slopes; the general pattern of drainage; the kinds of crops and native plants growing on the soils; and the kinds of bedrock. They observed and studied many soil profiles. Samples of some of the soils in the area are collected for laboratory analyses and for engineering tests. Soil boundaries were drawn on the soil maps and a locally tailored MUIR database was constructed, based on these observations and the resulting landscape model the soil scientist developed. 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.

The actual composition and interpretative purity of the map unit delineations were based on statistical analyses of field observations and transect data. 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 Service state soil scientist. Four kinds of map units are used in soil survey: 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 components 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 percnet if limiting and 25 percent if not limiting. 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 the 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 proportions 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 per 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 6 acres. 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.

Information includes, but is not limited to, state, soil survey area identification number, soil survey area name, map unit symbol and name, soil component name, linkage to the specific SIR records, layer-tailoring criteria, etc. Process Step Process Description: Field procedures for the second order soil survey are determined by field observations 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, if the soil survey has been correlated and published. The information is subject to change prior to final correlation and publication. Process Date: e.g. 1990 Source Used Citation Abbreviation: NRCS1 Process Step Process Description: Soil Interpretation Records (SIR) were created and edited for each soil in the United States. These records contain approximately 88 soil and nonsoil properties, interpretations, and yield and production information, and represent an aggregation of ranges of properties for everywhere that the soil is found. Process Date: 1994 Source Used Citation Abbreviation: NRCS1 Process Step Process Description: Map Unit Records (SOI-6) were created and edited for each map unit in every soil survey area in the United States. Basically, the SOI-6 is a form to query the SIR database to initially generate a preliminary Map Unit Interpretation Record (MUIR) database. A national collection of the SOI-6 records is contained in the Map Unit Use Files (MUUF) database. The SOI-6 form is used by the soil scientist to select and tailor the SIR data record to reflect local soil conditions. Properties tailorable through this process step include soil surface texture and thickness, all soil layer thickness, drainage, prime farmland status, and other selected properties. Process Date: e.g. 1994.

The creation, editing, error-checking, and maintenance of the SOI-6 and SIR databases were the responsibility of the NRCS State Soil Scientist and the State Soil Survey Database (SSSD) Manager. The processing of the SOI-6 (or MUUF) and SIR databases and the generation of the MUIR occured at the Statistical Laboratory, Iowa State University, Ames, Iowa. Process Date: e.g. 1994.

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 nonsoils. The state, soil survey area id symbol, and map unit symbol uniquely identify each closed delineation, map unit and form the key to uniquely link to a map unit name. These set of data elements also form the key for linking information in the Map Unit Interpretations Record tables. Map Unit Delineations are described by the Map Unit Interpretations Record 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 Soil Map Unit Interpretations Record database consist of the following relational tables(found in tabdir directory): codes (database codes) - stores information on all codes used in the database 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 ewoodlnd (existing woodland productivity) - store information on common indicator trees for soil map unit components forest (forest understory) - stores information for plant cover as forest understory for soil map unit components hydcomp (hydric soil component information) - stores data and information related to the hydric classification, criteria, landform, etc. inclusn (map unit inclusions) - stores the names of soils included in the soil map units 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 mucoacre (map unit county acres) - stores the number of acres for the map unit within the county muyld (map unit yield) - stores crop yield information for the soil map unit. plantcom (plant composition) - stores plant symbols and percent of plant composition associated with components of soil map units plantnm (plant name) - stores the common and scientific names for plants used in the database pwoodlnd (woodland) - store information on potential indicator trees for soil map unit components rangenm (range name) - stores the range site name. rsprod (range site production) - stores range site production information for soil map unit components sdbcodes (soil database codes) - stores database data dictionary information ssacoac (soil survey area county acreage) - stores the acreage for the county within the boundary of the soil survey area ssarea (soil survey area) - stores information that will apply to an entire soil survey area taxclass (taxonomic classification) - stores the taxonomic classification for soils in the database 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 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 Entity and Attribute Detail Citation U.S. Department of Agriculture. 1975.

The NRCS national MUIR database is a collection of soil survey attribute information. The general structural hierarchy of the information is by soil survey area, map units within the survey area, and map unit components within the map unit. To effectively download and use the data, one must understand the basic structure of the relational tables containing this information. Below is a listing of the tables, with a brief description, arranged to show their general relationship. Clicking on a table name will take you to a more detailed description of that table. These attribute tables can be found in the tabdir directory under tualatin/geomorph (one directory down from the location of the data layer).
