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. 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.

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.

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 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, Fairfield, Athens, and Ross Counties, Ohio. The survey area boundaries and soils have a perfect join. The quadrangles in this survey are edge matched to quadrangles in adjacent SSURGO certified soil survey, Perry County, Ohio, and the survey area boundaries 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 feature labels in edge matched surveys. Completeness_Report: 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 many 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 2.0 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 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. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: U. S.

(tabular) information Process_Step: Process_Description: Field procedures for the second order soil survey included plotting of soil boundaries determined by field observations in conjunction with aerial photo interpretation. 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 analyzed the data. The classification and map unit names were finalized at the final correlation conference in 1978 and signed in 1979. The published soil survey report was released in 1981. Source_Used_Citation_Abbreviation: NRCS1 Process_Date: 1981 Process_Step: Process_Description: Perfect map unit joins, involving field investigations, were conducted by Soil Scientists to provide seamless coverage with all adjacent Ohio, county soil surveys. Source_Used_Citation_Abbreviation: NRCS1 Process_Date: 2002 Process_Step: Process_Description: For each publication mapsheet, the original soil delineation overlay, special soil features overlay and photo background overlay were scanned by Draft-Co. Inc., Martins Ferry, Ohio. Each photo overlay was then aligned with its corresponding special features and soil delineation overlay in the CAD environment. This align was followed by a digital orthorectification process (SYRUP- Simple Yet Robust Universal Parametric-Orthorectification). Inputs into the model include the scanned and registered soil delineation overlays, special soil features overlays, and photo background overlays, as well as standard 1-meter resolution USGS digital ortho quarter quads (DOQQs), and a standard USGS 30-meter, seamless Digital Elevation Model (DEM). The first step in the SYRUP process is to obtain sufficient ground control points (GCPs) between each mapsheet overlay and its corresponding DOQQs. This is performed using ERDAS Imagine software (ERDAS, Inc., 2001). GCPs are recorded in a text file along with their associated elevation values gathered from the DEM and are input into the SYRUP model. The root mean square error (RMSE) of each individual control point and the average RMSE of all control points were calculated using X-file and Y-file coordinates, X-ground and Y-ground coordinates, and Z-elevation values. The RMSE describes the deviation between the actual location of a GCP and the value calculated by the transformation and must be lower than 10.00 for each mapsheet. The RMSE values were calculated by the ERDAS Imagine software, based on a two-dimensional registration, because this was the only type of registration ERDAS Imagine provides. Since ultimately a three dimensional registration (SYRUP) was being applied to the data, a specific RMSE value to be used as a "breakpoint" value for quality control purposes was not appropriate in this case. Rather, relative values were compared and used as an index to flag certain areas for further spatial examination and GCP adjustment. A spatial measurement was used as a rigid indicator of quality control. This is a measurement of the distance between mapsheet overlay locations after ortho-rectification and their corresponding actual DOQQ locations. Distance measurements were examined at extremely large scales (1:1,000 or larger) to assure compliance with minimum USGS National Map Accuracy Standards (NMAS). The SYRUP extension to ERDAS Imagine uses a statistical model involving a statistical approximation to produce a geometrically correct version of each publication mapsheet overlay. Resulting images were also visually compared with corresponding DOQQ images using the Swipe tool in ERDAS Imagine for quality. Problem areas in need of increased quality were edited by adding and/or adjusting control points where needed. These areas can then be processed through the SYRUP model once again. ERDAS Imagine was then used to convert the raster image (*.img) file format to .grid raster file format for viewing in ARC/INFO. The raster, soil delineation layer was then converted to a binary, raster .tif using AutoCAD. Hitachi software in a CAD environment was used to convert the binary raster lines into vector lines. AutoCAD software was used to clean vector lines and attribute the soil polygons with their appropriate soil map unit symbols. The clean lines were then "splined" using a quadratic B-spline in AutoCAD software and "generalized" using ESRI software. Bodies of water were aligned to the ortho photo image except for areas less than 2 acres in size. Areas less than 2 acres in size were shown as a point special feature labeled "WAT". Most errors found on the published soil maps were corrected by a soil scientist who referred to copies of the original soil survey field sheets. A few errors were field checked by soil scientists and corrected. The orthorectified special soil features overlays were used as a background reference image to determine which map unit symbols were associated with which soil polygons. Special soil features were also digitized and attributed as separate point and line coverages using AutoCAD. Cultural features are then exported out of AutoCad with the appropriate object data attached to each feature. The line work and symbols are processed using a series of queries and spatial joins in MapInfo. The formed polygons are then returned to AutoCad and written out as an ARC/INFO coverage for a final product. Quality assurance/quality control was conducted by the Ohio Department of Natural Resources. All Soil Line placements and labels were checked and verified. In addition, label placement locations for soil polygons were moved to the centroid of polygons where possible or to other locations to prevent the overlap of labels from adjoining polygons and special features. ARC/INFO software was used to edge match quarter quadrangles of soil data which were then merged into a county-wide layer. The official Ohio statewide county boundary for Hocking County, Ohio was edited to the coverage. This coverage is presently being reviewed by the USDA, Natural Resources Conservation Service for compliance with SSURGO standards. This review may require that some changes by made to the data.
