Federal Geographic Data Committee

Established by Office of Management and Budget Circular A-16, the Federal Geographic Data Committee (FGDC)

promotes the coordinated development, use, sharing, and dissemination of geographic data.

The FGDC is composed of representatives from the Departments of Agriculture, Commerce, Defense, Energy, Housing

and Urban Development, the Interior, State, and Transportation; the Environmental Protection Agency; the Federal

Emergency Management Agency; the Library of Congress; the National Aeronautics and Space Administration; the

National Archives and Records Administration; and the Tennessee Valley Authority. Additional Federal agencies

participate on FGDC subcommittees and working groups. The Department of the Interior chairs the committee.

FGDC subcommittees work on issues related to data categories coordinated under the circular. Subcommittees

establish and implement standards for data content, quality, and transfer; encourage the exchange of information and

the transfer of data; and organize the collection of geographic data to reduce duplication of effort. Working groups are

established for issues that transcend data categories.

SOIL GEOGRAPHIC DATA STANDARD

1. Introduction

The Soil Geographic Data Standard is composed of several components that describe a data content

standard.

1.1 Purpose

The purpose of this standard is to standardize the names, definitions, ranges of values, and other

characteristics of soil survey map attribute data developed by the National Cooperative Soil Survey

(NCSS). The NCSS is the body composed of the various federal, state, and local units of government who

work cooperatively to develop the soil survey of all lands in the United States.

The soil attribute data associated with soil maps include the physical and chemical properties of the various

soils being described, interpretative information, the arrangement of these soils into the soil map units

identified on the soil maps, and information about the soil map units themselves. The attribute data have

no spatial relationship until they are linked to the maps via the map unit symbol and other unique

identifiers. However, there is information included linking the soil data to geographical areas such as

counties, states, major land resource areas, and soil survey areas.

The USDA-Natural Resources Conservation Service (former Soil Conservation Service) has been identified

by the Federal Geographic Data Committee to coordinate the development of standards for the transfer of

soil data. A representative of this agency serves as chairman of the FGDC Soil Data Subcommittee.

When adopted, this standard should facilitate the transfer and use of soil data. It will allow users of such

data to receive data in a common format, no matter who the developer of the data is. It will allow much

more data to be available to a more diverse group of users.

1.2 Scope

This standard applies to the tabular data associated with the soil survey maps developed by the National

Cooperative Soil Survey at scales of about 1:12,000 to 1:30,000. It contains data of and about soil map

units and map unit components.

The standard does not pertain to data gathered at a specific location -- point or site data. Standards for

point/site data will likely be developed at a future time. Point data are used to develop the ranges for map

unit components. As data is gathered while conducting a soil survey, the data from individual points are

classified using accepted procedures and grouped or aggregated into similar soil types. The various soil

types become components of map units.

The standard references and builds on some long established standards including SOIL TAXONOMY,

THE SOIL SURVEY MANUAL, and THE SOIL SURVEY LABORATORY METHODS MANUAL.

Soil Taxonomy is the comprehensive classification system by which soils are classified based on their

physical and chemical properties. It is used throughout the US and several foreign countries. Other

classification systems, such as the American Association of State Highway and Transportation Officials

(AASHTO), and the Unified Soil Classification System (USCS) are also used. The AASHTO and Unified

systems are based more on engineering related properties. Data elements are included to identify the

AASHTO and USCS classification for each soil horizon included in the data base. The two manuals

contain procedures to be used in the field and lab to develop standard soil information. The NRCS

National Soil Survey Handbook provides additional guidance.
Federal Geographic Data Committee FGDC-STD-006

Soil Geographic Data Standard, September 1997

These existing standards have been accepted by the National Cooperative Soil Survey as the standards by

which soil survey work will be done. The procedures contained in these standards have been used in excess

of 30 years, and have been modified and improved during this time period as the need was identified.

1.3 Limits

This standard is limited to data associated with soil maps and associated attribute data (aggregated data),

generally at scales of about 1:12,000 to 1:30,000. As presented at this time, the standard does not contain

information dealing with the description of landforms and landscapes, or vegetation related to soil map

units. This information will be added at a future time once the respective interagency groups complete

work on these subjects. The standard classification of vegetation types developed by the FGDC Vegetation

Subcommittee will likely be incorporated also.

It should be understood that the list of data elements included in the standard will likely be modified and/or

added to as new or additional data are identified as being needed for various uses. These modifications will

be submitted for acceptance when necessary, and advertised to known users of the standard.

An additional part of the standard will likely be developed to deal with point or site data (pedon

descriptions and laboratory analyses). Other additions may also be developed for data to accompany soil

maps at other scales.

1.4 Development Process

This standard is the result of a cooperative effort. Initial meetings were held in the Fall of 1992 with

progress being made since that time. A work group under of the FGDC Soils Subcommittee composed of

representatives of several federal agencies and universities developed much of the proposed standard.

Agencies involved include the Natural Resources Conservation Service, Forest Service, Bureau of Land

Management, Environmental Protection Agency, Agricultural Research Service, and the Agricultural

Experiment Stations. The proposed standard was then reviewed and accepted by the NCSS Standards

Committee and the FGDC Soils Subcommittee.

1.5 Maintenance

A team has been approved and members appointed by the FGDC Soils Subcommittee to maintain and

enhance this standard. The Natural Resources Conservation Service is the lead agency responsible for

maintenance.

Membership is as follows:

Jim Fortner, NRCS, Lincoln, NE, (team leader)

Russ Kelsea, NRCS, Lincoln, NE

Jim Keys, USFS, Atlanta, GA

Scott Davis, BLM, Denver, CO

Wayne Hudnall, LSU, Baton Rouge, LA

John Doran, ARS, Lincoln, NE

William McMahon, DMA-DOD, Fairfax, VA

Craig Palmer, EPA, Las Vegas, NV

Other agencies/entities such as the U.S. Fish and Wildlife Service, Bureau of Indian Affairs, Bureau of

Reclamation, Bureau of Mines, Biological Survey, and U.S. Park Service will be contacted for input

related to data relative to their specialty, on an as-needed basis. The existing NCSS work planning

processes and state contacts will be utilized to allow for input from other concerned parties.

This team will use the following procedures to process proposals to modify or add to the standard:
Federal Geographic Data Committee FGDC-STD-006

Soil Geographic Data Standard, September 1997

• Each team member will receive, review and organize proposals originating within their

respective agency/entity. They will then forward a recommendation for action to the team

leader.

• The existing NCSS Work Planning Conference structure, and state contacts, will be used to

allow for input from industry, non-industrial landowners, and non-traditional users to the team.

• The team leader will route the proposal along with the originating agency's recommendation to

team members for review and recommendation.

• The team will make the final decision. Each represented agency will have equal voting rights --

one vote per agency/entity.

• An appeal procedure will be established to allow for direct presentation of proposals to the team

leader.

• A feedback and tracking mechanism will be established to ensure that originators of proposals

are informed of actions taken on their proposals.

• A minimum standard for documentation to accompany all proposals will be established.

• A mechanism to get input and/or review of proposals from agencies not represented on the team

will be established.

• A scheme to ensure timely review and processing of proposals will be established.

• The data set will be maintained by the Natural Resources Conservation Service staff.

2. Content of the Standard

The standard contains a listing of data elements used to store the various physical, chemical, and

interpretive data associated with soils described in a soil survey. Soil surveys are structured to cover a

specific geographic portion of the United States. This geographic area is portrayed by the area object in

the database.

A printout of the data dictionary of the data elements is included which contains the name, definition, field

length, data type, precision, allowable ranges or entries as is appropriate, and whether or not it is reported

with a High, Low, and Representative Value (RV) for each data element.

Included in the list of data elements are various pairs that end with “iid” and “iid_ref” which have the same

definition. The definitions are generic in nature explaining what the “iid” and “iid_ref” numbers represent.

The definitions are not specific to the particular data elements listed. These elements serve as links

between the various tables to maintain referential integrity among the data.

The following documents are provided to detail the content of the standard and to show the relationships

among the data:

• An Entity Relationship Model which lists the various tables in the database, and their

relationship to one another. The purpose of the model is only to demonstrate the relationships

between the data, not to specify any particular structure of the database. The relationships

within the data is very important in order to properly utilize the data as it is intended.

• A listing of the table names in the data base with data elements contained in each.
Federal Geographic Data Committee FGDC-STD-006

Soil Geographic Data Standard, September 1997

• A listing of the soil property and interpretative data elements included in the data base. This list

matches those contained in the data dictionary printout (Item 5 below).

• A listing of descriptions/definitions for some of the choices listed for various data elements.

This is not a complete list at this time as all definitions have not been entered into the data

dictionary data base. Other definitions may also be found in the Soil Survey Manual or the

National Soil Survey Handbook references.

• A computer printout of the data dictionary.

 aashto_group_classification aashtocl choice

 DEFINITION

 A system that classifies soils according to those properties that affect roadway construction and maintenance. Soils are

 classified into seven basic groups plus eight subgroups, for a total of fifteen for mineral soils. Another class for organic

 soils is used. The groups are based on determinations of particle-size distribution, liquid limit, and plasticity index. The

 group classification, including group index, is useful in determining the relative quality of the soil material for use in

 earthwork structures, particularly embankments, subgrades, subbases, and bases.

 AGGREGATION METHOD IS a repeating group with RV.

Description

Abstract: This data set is a digital soil survey and is the most detailed level of soil geographic

data developed by the National Cooperative Soil Survey. The information was collected 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 __(3)__ minute quadrangle format and include a detailed, field verified

inventory of soils and nonsoil areas that normally occur in a repeatable pattern on the landscape

and that can be cartographically shown at the scale mapped. Sometimes a special soil features

layer (point and line features) is included. 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

Map Unit Interpretations Record relational data base, which gives the proportionate extent of the

component soils and their properties.

Purpose: SSURGO depicts information about soil features on or near the surface of the Earth.

These data were collected 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.

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.

Geospatial Data Presentation Form: text, table, map

Description

Abstract: This soil survey contains information that can be applied in managing farms and

wetlands; in selecting sites for roads, ponds, buildings, and other structures; and in judging the

suitability of tracts of land for farming, industry, and recreation.

Purpose: This soil survey depicts information about soil features on or near the surface of the

Earth. These data were collected as part of the National Cooperative Soil Survey.

Data Quality Information

Attribute Accuracy

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.

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

Soil Geographic Data Standard, September 1997

272

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.

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 Agricultural Handbook 18, Soil Survey Manual, 1993, USDA, SCS; Agricultural

Handbook 436, Soil Taxonomy, Soil Survey Staff, 1975, USDA, SCS; and all Amendments;

Keys to Soil Taxonomy, Soil Survey Staff, (current issue); National Soil Survey Handbook, title

430-VI, 1996.

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.

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 component 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 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 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 a

scale of about 1:24,000. The major components of an association can be separated at a scale
Federal Geographic Data Committee FGDC-STD-006

Soil Geographic Data Standard, September 1997

273

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 proportion 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 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 ___(21)___ 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. 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.

Entity and Attribute Information

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 nonsoil areas.

The map unit symbol uniquely identifies each closed delineation map unit. Each symbol is

linked to a map unit name. The map unit symbol is also the key for linking information in the

Map Unit Interpretations Record tables. The map unit symbols are not carried within the

modified Digital Line Graph file; however, they are made available in a companion attribute file.

The attribute file links the minor codes in the Digital Line Graph files to the map unit symbols.

Map Unit Delineations are described by the Map Unit Record data base. This attribute data

base gives the proportionate extent of the component soils and the properties for each soil. The

data base 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.

Special features are described in the feature table. It includes a feature label, feature name, and

feature definition for each special and ad hoc feature in the survey area.
