Abstract
STATSGO2 consists of general soil association units. It was developed by the National Cooperative Soil Survey and supersedes the State Soil Geographic (STATSGO) data set published in 1994 .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 data set 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 data set 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 data set. It is distributed in state/territory and national extents. The soil map units are linked to attributes in the National Soil Information System data base which gives the proportionate extent of the component soils and their 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.The data should be displayed and analyzed at scales appropriate for 1:250,000-scale data.

Use Restrictions
The U.S. Department of Agriculture, Natural Resources ConservationService should be acknowledged as the data source in productsderived from these data. Hardcopies utilizing these data shallclearly indicate their source. User agrees not to misrepresent thesedata, nor to imply that changes made were approved by the NaturalResources Conservation Service.The Digital General Soil Map of U.S. was designed primarily forregional, multicounty, river basin, State, and multistate resourceplanning, management, and monitoring. Data are not detailed enoughto make interpretations at a county level. This soil survey productis not designed for use as a primary regulatory tool in permittingor citing decisions, but may be used as a reference source. The useof these data is not restricted and may be interpreted by organizations,agencies, units of government, or others; however, they are responsiblefor its appropriate application. Federal, State, or local regulatorybodies are not to reassign to the Natural Resources ConservationService any authority for the decisions that they make. The NaturalResources Conservation Service will not perform any evaluations ofthese maps for purposes related solely to state or local regulatoryprograms.When data from the Digital General Soil Map of U.S. are overlayedwith other data layers, such as land use data, caution must beused in generating statistics on the co-occurence of the land usedata with the soil data. The composition of the soil map unit canbe characterized independently for the land use and for the soilcomponent, but there are no data on their joint occurrence at amore detailed level. Analysis of the overlayed data should be on amap polygon basis.Additional political, watershed, or other boundaries may beintersected with the soil data. Although the composition of eachpolitical and watershed unit may be described in terms of thesoil map units, information is not available to assign thecomponents to the boundary units with full accuracy. As with theland use categories, the analysis should be restricted to theclassified components.The approximate minimum area delineated is 625 hectares(1,544 acres), which is represented on a 1:250,000-scale map byan area approximately 1 cm by 1 cm (0.4 inch by 0.4 inch). Lineardelineations are not less than 0.5 cm (0.2 inch) in width. Thenumber of delineations per 1:250,000 quadrangle typically is 100to 200, but may range up to 400. Delineations depict the dominantsoils making up the landscape. Other dissimilar soils, too smallto be delineated, are present within a delineation.Digital enlargements of these data to scales greater than atwhich they were originally mapped can cause misinterpretationof the data. If enlarged, maps do not show the small areas ofcontrasting soils that could have been shown at a larger scale.The depicted soil boundaries, interpretations, and analysisderived 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 forplanning purposes only.Data values for some data elements may be incomplete or missing.Where data are unavailable, a mask should be used to exclude thearea from analysis.The spatial and tabular data used to create this product areperiodically updated. Data are versioned, and users are responsiblefor obtaining the latest version of the product.

Data Quality Information
Attribute Accuracy Report
Accuracy is tested by manual comparison of the source with hardcopy plots and/or symbolized display of the map data on aninteractive computer graphic system. Selected attributes thatcannot be visually verified on plots or on screen are interactivelyqueried and verified on screen. In addition, the attributesare tested against a master set of valid attributes. All attributedata conform to the attribute codes in the signed classificationand correlation document and amendments and are current as ofthe date of digitizing.
Logical Consistency Report
Certain node/geometry and topology (GT)-polygon/chainrelationships are collected or generated to satisfy topologicalrequirements. (The GT-polygon corresponds to the soil delineation).Some of these requirements include: chains must begin and end atnodes, chains must connect to each other at nodes, chains do notextend through nodes, left and right GT-polygons are defined foreach chain element and are consistent throughout, and the chainsrepresenting the limits of the file (neatline) are free of gaps.The tests of logical consistency are performed using vendorsoftware. The neatline is generated by connecting the explicitlyentered four corners of the digital file. All data outside theenclosed region are ignored and all data crossing thesegeographically straight lines are clipped at the neatline. Datawithin a specified tolerance of the neatline are snapped to theneatline. Neatline straightening aligns the digitized edges ofthe digital data with the generated neatline (i.e., with thelongitude/latitude lines in geographic coordinates). All internalpolygons are tested for closure with vendor software and arechecked on hard copy plots. All data are checked for common soillines (i.e., adjacent polygons with the same label). Quadranglesare edge matched within the state, merged into a statewide datasets, and then edge matched to adjacent state data sets. Edgelocations do not deviate from centerline to centerline by morethan 0.01 inch.
Completeness Report
A map unit is a collection of areas defined and named the samein terms of their soil and/or nonsoil areas. Each map unit differsin some respect from all others in a survey area and is uniquelyidentified. Each individual area is a delineation. Each map unitin the Digital General Soil Map of U.S. consists of one to morethan 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 todelineate map units and estimate the percentages of components.Map unit components in this product are soil series phases, andtheir percent composition represents the estimated areal proportionof each within a map unit. The composition for a map unit isgeneralized to represent the statewide extent of that map unitand not the extent of any single map unit delineation. Thesespecifications provide a nationally consistent representation ofthe associated attribute data.The actual composition and interpretive purity of the map unitdelineations were based on statistical analysis of transect data.The composition was largely determined by measuring transects ondetailed soil survey maps. The number of transects used wasproportional to the relative size, number, and complexity of thedelineations. The combined data on the length of the map unitscrossed by the transects were used to determine the percentagesof the different soil and nonsoil areas in each map unit.Specific National Cooperative Soil Survey Standards andprocedures were used in the classification of soils, design andname of map units. These standards are outlined in U.S. Departmentof Agriculture. 2nd Ed., 1999. Soil Taxonomy: A basic system ofsoil classification for making and interpreting soil surveys.Nat. Res. Conserv. Serv., U.S. Dep. Agric. Handb. 436.; U.S.Department of Agriculture. 9th Ed., 2003. Keys to Soil Taxonomy.Soil Surv. staff, Nat. Res. Conserv. Serv.; U.S. Department ofAgriculture. Current Issue. National Soil Survey Handbook, title430-VI. Soil Surv. Staff, Nat. Res. Conserv. Serv.; and U.S.Department of Agriculture. 1993. Soil Survey Manual. Soil Surv.Staff, U.S. Dep. Agric. Handbook 18.Adherence to National Cooperative Soil Survey standards andprocedures is based on peer review, quality control, and qualityassurance. Quality control is outlined in documents that residewith the Natural Resources Conservation Service state soilscientist.
Horizontal Positional Accuracy Report
The accuracy of these digital data is based upon theircompilation to base maps that meet National Map AccuracyStandards. The difference in positional accuracy betweenthe map unit boundaries in the field and their digitizedmap locations is unknown. The locational acuracy of soildelineations on the ground varies with the transitionbetween map units.For example, in areas where changes in soils, climate,topography, and geology occur subtly across a portion of astate, the transition between soil map unit boundaries willbe gradual. Where these features change abruptly, such asfrom an area of foothills to a lake plain, the transitionwill be very narrow. Soil delineation boundaries weredigitized within 0.01 inches of their locations on thedigitizing source. The digital map elements are edge matchedbetween data sets. The data along each state boundary arematched against the data for the adjacent state. Edgelocations generally do not deviate from centerline tocenterline by more than 0.01 inch.

Entity and Attribute Overview
Map Unit Delineations are closed polygons that are geographicmixtures of groups of soils or soils and nonsoil areas.The map unit key uniquely identifies each closed map unitdelineation. Each map unit key is linked to a map unit symboland a map unit name. The map unit key is also the key for linkinginformation in the National Soil Information System tables.Map Unit Delineations are described by the National SoilInformation System data base. This attribute data base gives theproportionate extent of the component soils and the propertiesfor each soil. The data base contains both estimated and measureddata on the physical and chemical soil properties and soilinterpretations for engineering, water management, recreation,agronomic, woodland, range and wildlife uses of the soil.The National Soil Information System data base contains staticmetadata. It documents the data structure and includes suchinformation as what tables, columns, indexes, and relationshipsare defined as well as a variety of attributes of each of thesedata base objects. Attributes include table and column descriptionsand detailed domain information.The National Soil Information System data base also containsdistribution metadata. It records the criteria used in the setof distributed data.
