1.8 Use Constraints:

The U.S. Department of Agriculture, Natural Resources Conservation Service and the South Carolina Department of Natural Resources 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.

DATA QUALITY INFORMATION

2.1 Attribute Accuracy:

2.1.1 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) and are current as of the date of digitizing.

2.1.2 Quantitative Attribute Accuracy Assessment:

2.1.2.1 Attribute Accuracy Value:

2.1.2.2 Attribute Accuracy Explanation:

2.2 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.

2.3 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 nonsoil areas (special soil features) that have properties and behavior significantly different than the named soils in the surrounding map unit. Other inclusions that have a minimal effect on use and management, or those that could not be precisely located, were not mapped.

Specific limits were established on the classification of soils, design and name of map units, location of special soil features, and the percentages of allowable inclusions. These limits are outlined in U.S. Department of Agriculture. 1975. Soil Taxonomy: A basic system of soil classification for making and interpreting soil surveys. Soil Conserv. Serv., U.S. Dep. Agric. Handb. 436.; U.S. Department of Agriculture. 1992. Keys to Soil Taxonomy. SMSS Technical Monograph No. 19. Soil Surv. Staff, Soil Conserv. Serv.; U.S. Department of Agriculture. 1993. National Soil Survey Handbook, title 430-VI. Soil Surv. Staff, Soil Conserv. Serv.; and U.S. Department of Agriculture. 1993. Soil Survey Manual. Soil Surv. Staff, U.S. Dep. Agric. Handb. 18.

The actual composition and interpretive purity of the map unit delineations were based on statistical analysis 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 Conservation Service state soil scientist. Four kinds of map units are used in soil surveys: consociations, complexes, associations, and undifferentiated groups.

2.4 Positional Accuracy:

2.4.1 Horizontal Positional Accuracy:

2.4.1.1 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.

Edgematch

During the edgematching process alternating quads were brought into Arc Edit as edit coverages. Using the NRIMA 7.5 minute reference guide, only alternating, or hatched quads were selected as edit coverages in an attempt to prevent migration of features. Surrounding quads were brought up as back coverages, and arcs or polygons that traversed quad boundaries were edgematched with a degree of error of less than .5 meter. Any arc on the edit coverage that approached the quad boundary but did not have a corresponding arc on the back coverage was given an error code of Ea00, referring to an arc feature not continued over a quad boundary with no correction made. All edit coverage arcs that were moved to align with back coverage arcs with a measure of error of less than .5 meter were coded as either Ed12 or Eb12 in the edgenote item. Ed12 being the code given to arcs that were off by more than .5 meter but less than 15 meters. Eb12 was the code given to arcs that were off by more than 15 meters. The direction in which the arc was moved to be closer to the corresponding back coverage arc was noted in the mdir item field, and the distance between the edit coverage arc and the corresponding back coverage arc was recorded in the mdist item field.

Attribute

During the attributing phase of data development, feature attribute values are compared to a source map specific to the data layer. These maps include 1:24,000 USGS 7.5 minute topographic maps,USF&WS NWI Wetlands maps, NRCS County Soil Survey maps, and General Highway maps. Edits are then executed based on comparisons of the digital data to these source maps.

Quality Review - Phase I

During the 1st quality control and quality analysis phase, feature attribute values are examined internal to the coverage and across quad boundaries using custom AML's, frequencies, and visual checks in ArcEdit. Topological errors are corrected to insure a successful mapjoin at the end of this process step.

Quality Review - Secondary Phase

During the 2nd quality control and quality analysis phase, feature attribute values are again examined internal to the coverage and across quad boundaries using custom AML's, frequencies, and visual checks in ArcEdit. These checks are performed by a second tier database developer. Topological errors are corrected to insure a successful mapjoin at the end of this process step.

Quality Review - Final Phase

The tertiary quality review process is the final QA phase and consists of thorough reviews of the data layer. These inspections are aimed at identifying any remaining errors and inconsistencies in the data. The process involves running a series of Arc/Info macros (AMLs), the first of which logs all errors and recommends corrections. The attributes of each feature (arc and polygon) are compared to a master attribute list and any discrepancies and omissions are logged. All features are then reattributed and then all quads are mapjoined and mismatches in attributes across quadrangle boundaries are identified, tagged, inspected and corrected if necessary. Frequencies are then run on items of the .aat and .pat (when necessary) to identify any remaining features which have not been attributed. Finally, random manual quadrangle spot checks are performed and corrections made when necessary. All coverages are then exported (COMPRESS=FULL) and placed on the public web server for dissemination.
