Walworth County, Wisconsin SSURGO https://websoilsurvey.sc.egov.usda.gov/ 30.629 File Geodatabase Feature Class A_B_SoilSlopes 2019-09-14 U.S. Department of Agriculture, Natural Resources Conservation Service Fort Worth, Texas U.S. Department of Agriculture, Natural Resources Conservation Service wi127 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 soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous 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. 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.

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 are free of gaps. The tests of logical consistency are performed using vendor software. 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). Edge locations generally do not deviate from centerline to centerline by more than 0.01 inch. The quadrangles in this survey are edge matched to quadrangles in adjacent SSURGO certified soil surveys, Kenosha and Racine, Rock, Jefferson, and Milwaukee and Waukesha Counties, Wisconsin, and McHenry County and Boone County, Illinois, and the survey area boundaries are an exact match. Most feature edges (polygon and line segments) match adjacent ones in the edge matched survey areas, however, most feature labels don't match the adjacent features labels in edge matched surveys. Descriptive attributes (tabular information about the polygons and line segments)were developed specifically for each survey area. Although most don't match exactly, the descriptive attributes of most polygon and line segments in this survey are nearly the same as adjacent ones in edge matched soil surveys.

A map unit is a collection of areas defined and named in terms of their soil components or miscellaneous areas or both. Each map unit differs in some respect from all others in a survey area and each map unit has a symbol that uniquely identifies the map unit on a soil map. Each individual area, point, or line so identified on the map is a delineation. Soil Scientists identify small areas of soils or miscellaneous 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 many not be indicated on the map. A map unit has specified kinds of soils or miscellaneous areas (map unit components), each with a designated range in proportionate extent. Map units include one or more kinds of soil or miscellaneous area. Miscellaneous areas are areas that have little or no recognizable soil. 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, NRCS; Agricultural Handbook 436, Soil Taxonomy, 1995, USDA, NRCS; and all Amendments; Keys to Soil Taxonomy, (current issue) USDA, NRCS; National Soil Survey Handbook, title 430-VI,(current issue) USDA, NRCS. 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 use a single name from the dominant component in the map unit. Dissimilar components are minor in extent. The soil component in a consociation may be identified at any taxonomic level. Soil series is the lowest taxonomic level. A consociation that is named as a miscellaneous area is dominantly that kind of area and minor components do not significantly affect the use of the map unit. 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 consist of two or more dissimilar components that occur in a regularly repeating pattern. The total amount of other dissimilar components is minor extent. The following arbitrary rule determines whether complex or association is used in the name. The major components of an association can be separated at the scale of mapping. In either case, because the major components are sufficiently different in morphology or behavior, the map unit cannot be called a consociation. In each delineation of 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 are not consistently associated geographically and, therefore, do not always occur together in the same map delineation. These components are included in the same named map unit because their use and management are the same or very similar for common uses. Generally they are grouped together because some common feature, such as steepness, stoniness, or flooding, determines their use and management. If two or more additional map units would serve no useful purpose, they may be included in the same unit. Each delineation has at least one of the major components, and some may have all of them. The same principles regarding the proportion of minor components that apply to consociations also apply to undifferentiated groups. The same principles regarding proportion of inclusion 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 3 acres. The 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). The accuracy of these digital data is based upon their compilation to base maps that meet National Map Accuracy Standards at a scale of 1 inch equals 1,000 feet. 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. Ratio film positives, 1:12000 scale, were made from the publication annotation overlays. Soil map unit delineations and special soil features were manually compiled to stable-base overlays registered to 1:12000 scale, 3.75 minute orthophotographic quadrangles. 2003-01-01 NRCS1, NRCS2, NRCS3 The spatial data for Walworth County, Wisconsin soil survey area were downloaded from the Soil Data Mart on October 15, 2012. The individual shapefiles were appended into a geodatabase for region 11. The data were processed in ARCGIS 10.1 using a topology object with a 0.1 meter cluster tolerance for the purpose of eliminating gaps and overlaps within the region 11 soils geodatabase. Individual soil survey area data were exported as shapefiles from the regional geodatabase. A datum transformation from NAD83 to WGS84 using the NAD_1983_To_WGS_1984_1 datum transformation method was applied to the data. The data were checked with the SSURGO Evaluation scripts provided by U.S. Department of Agriculture, Natural Resources Conservation Service. The shapefiles were uploaded to the soil data warehouse for archival and distribution. 2013-01-01 NRCS8 The Natural Resources Conservation Service State Soil Scientist or delegate verified that the labels on the digitized soil map units link to map units in the tabular database, and certified the joined data sets for release to the Soil Data Warehouse. A system assigned version number and date stamp were added and the data were copied to the data warehouse. The tabular data for the map units and components were extracted from the data warehouse and reformatted into the soil data delivery data model, then stored in the Soil Data Mart. The spatial data were copied to the Soil Data Mart without change. 2019-09-14 NASIS The spatial data for the entire SSURGO database was recertified in October of 2019 to reduce storage requirements and to improve map display and geoprocessing performance. The SSURGO data is internally managed using 12 Regional Transactional Spatial Databases (RTSD) that are in an ESRI File Geodatabase format. The spatial extent of the RTSDs follow the Soil and Plant Science Division (SPSD) regional administrative boundaries. The XY coordinate system of this RTSD is USA Contiguous Albers Equal Area Conic USGS Version WKID: 102039 and has an XY storage precision of 0.001 meters. The RTSDs were recreated using a reduced storage precision of 0.1 meters to reduce the physical size of the data. The SSURGO data was also generalized by removing excess vertices, using a tolerance of 1 meter. The topology was validated at the CONUS level using a tolerance of 0.2 meters. This effort directly affects the gSSURGO and gNATSGO product since these deliverables are in a File Geodatabase format. 2019-01-01 NRCS8 TAM3: Data elements that comprise the Forage Suitability Groups were added to the major soil components in most mapunits. However, most major components named as miscellaneous areas, i.e. water, gravel pits, quarries, etc., other components lacking sufficient soil property data to assign them to a Forage Suitability Group, and any minor components were not populated with this new information. This new soil data interpretation and a number of quality control checks were provided to improve accuracy and interpretation for soils data users. 2009-04-23 NASIS The spatial data were downloaded from Soil Data Mart by the Wisconsin Digitizing Unit in Madison, Wisconsin. The data were processed in ARCGIS 9.2 using a topology object with a 0.1 meter cluster tolerance for the purpose of eliminating gaps and overlaps along the shared boundaries of Rock County, Jefferson County, and Milwaukee and Waukesha County, and Kenosha and Racine County Wisconsin and Boone County and McHenry County, Illinois. Additional edits were made to resolve any gaps or overlaps that exceeded the 0.1 meter cluster tolerance. In ARC/INFO, the Walworth County data were generalized with a tolerance of one meter to reduce vertex density for the purpose of reducing the overall database size. During this process measures were taken to insure the line quality was not degraded. The data were checked with the SSURGO Evaluation AMLs provided by U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center for accuracy and completeness. The data were processed using May, 2004 Recert AMLs provided by NCGC and submitted to the Soil Data Warehouse for archival and distribution. 2010-05-05 NRCS7 The tabular data was updated in accordance with National Bulletin 430-5-7 dated August 25, 2005. Data elements which may have been populated or edited include, legend status and legend area overlaps. Component data which may have been populated or edited include component names, local phases, MAAT, MAP, frost free days, percentage, kind, slope, drainage class, parent material, classification, geomorphic description, morphometry, aspect, T, WEI, WEG, hydrologic group, flooding and ponding duration and frequency, moisture status, hydric interpretation, restrictions and component text. Horizon data which may have been populated or edited include designation, depth, texture, structure, rock fragments, sand separates, total sand, total silt, total clay, organic matter, Ksat, Kw, Kf, pH, albedo dry, LEP, bulk density; water content, hydraulic conductivity, liquid limit, plasticity index, calcium carbonate, SAR, gypsum, CEC-7 and ECEC, and sum of bases. No changes were made to the spatial data. Interpretations for the Department of Homeland Security and the military were also added to this tabular version. All minor components are included. 2007-02-15 NASIS Walworth County had a previously published soil survey 1971, at 1:15840 scale. An evaluation was made of the soil survey in 1998. It was determined that the soil map unit delineations and map unit components were accurate. 1998-01-01 SCS1 Landforms were assigned to all hydric soils in the soil database. The spatial data were copied to the Soil Data Mart without change. 2006-01-20 NASIS The data were sent to the U.S. Department of Agriculture, Natural Resources Conservation Service, Wisconsin Digitizing Unit, Madison, Wisconsin (WIDU). The annotated soil delineation overlays were sent to Midwest Graphics, Kenosha, Wisconsin for raster scanning at 250 dpi on an Intergraph Anatach scanner in rlc format. The raster scanned data were imported into LT4X Version 4.1.1 maps. Once all the scanned soil lines were added to the maps, a county border was added. The border was digitized on screen from DRGs and DOQ??s in ArcGis. The special soil features were manually digitized from the annotated soil delineations in LT4X at a resolution of 0.01 inch. The raster editing, labeling, edge matching, and vector conversion were done in LT4X. Check plots of the soils and special soil features were reviewed by a soil scientist and cartographic staff at the WIDU. A ten percent quality assurance review was done of the soils and special features by a senior soil scientist at WIDU on behalf of the Major Land Resource Area office in Saint Paul, Minnesota. The soils and special soil features data were run through a series of LT4X macros for correctness and completeness. These macros smoothed and thinned out linework, added nodes for every 3000 vertices, added corner nodes and snapped nodes across the neatlines. The soils and special soil features data were then exported as Digital Line Graph-3 Optional format files (DLGs) in LT4X. The DLGs were evaluated with the modified Oct. 1998 ARC/INFO SSURGO Evaluation AMLs provided by U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center, Fort Worth, Texas (NCGC). Upon successful completion of the SSURGO Evaluation, the DLGs were rewritten from ARC/INFO Version 7.2.1. The SSURGO generated DLGs were rechecked with the SSURGO Evaluation AMLs. The SSURGO data and NASIS SSURGO download tabular data were processed with the February 2004 archiving AMLs provided by NCGC. The certified data were submitted to the Soil Data Warehouse for archival and distribution. 2003-01-01 NRCS4, NRCS5, NRCS6 Updating the interpretations to include AWM Sensitive Soil Features Wisconsin. CM 2012-06-26 NASIS The Natural Resources Conservation Service State Soil Scientist or delegate, upon completion of data quality verification, determined that the tabular data should be released for official use. A selected set of map units and components in the soil survey legend was copied to a staging database, and rating values for selected interpretations were generated. The list of selected interpretations is stored in the database table named sainterp. 2019-09-14 NASIS base for county border 12000 digital orthophotographic quadrangles (DOQs) NRCS6 1993-20-01 U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center Fort Worth, Texas U.S. Department of Agriculture, Natural Resources Conservation Service remote-sensing image date aerial photography was flown 1988-01-01 2000-01-01 Source of digital revision - recreated yearly region 11 soils geodatabase NRCS8 U.S. Department of Agriculture, Natural Resources Conservation Service file geodatabase SSURGO publication date 2006-01-01 2018-01-01 source for county boundaries 24000 Digital Raster Graphic Mosaic of Walworth County, Wisconsin NRCS5 2002-01-01 U.S. Department of Agriculture, Natural Resources Conservation Service U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center Fort Worth, Texas map source map 1976-01-01 1994-01-01 re-archiving source Soil Survey Geographic (SSURGO) database for Walworth County, Wisconsin NRCS7 2004-03-24 U.S. Department of Agriculture, Natural Resources Conservation Service U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center Fort Worth, Texas vector digital data publication date 2010-04-05 attribute (tabular) information National Soil Information System (NASIS) data base NASIS 2004-01-01 U.S. Department of Agriculture, Natural Resources Conservation Service Fort Collins, Colorado U.S. Department of Agriculture, Natural Resources Conservation Service unknown publication date 2004-01-01 2004-01-01 scanning source 12000 annotated soil delineation overlays NRCS4 U.S. Department of Agriculture, Natural Resources Conservation Service map date aerial photography was flown 1988-01-01 2000-01-01 base material for compilation and a reference for compilation of cultural features 12000 multiple 3.75 minute orthophotographic quadrangles NRCS3 1992-20-00 U.S. Department of Agriculture, Natural Resources Conservation Service U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center Fort Worth, Texas remote-sensing image date aerial photography was flown 1988-01-01 2000-01-01 source material for special soil features and soil attributes 12000 ratio film positives of publication annotation overlays NRCS2 U.S. Department of Agriculture, Natural Resources Conservation Service remote-sensing image final correlation date 1966-01-01 final publication negatives used to develop ratio film positives 15840 publication annotation overlays NRCS1 U.S. Department of Agriculture, Natural Resources Conservation Service map field final correlation date 1966-01-01 information for soil map unit delineations, special soil feature locations and data on soil properties 15840 Soil Survey of Walworth County, Wisconsin SCS1 1971-01-01 U.S. Government Printing Office Washington, D.C.

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 an area symbol, feature label, feature name, and feature description for each special and ad hoc feature in the survey area.
