Description:

Abstract:

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 7.5 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. 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 Map

Unit Interpretations Record 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.

Access_Constraints: None

Use_Constraints:

The U.S. Department of Agriculture, Natural Resources Conservation

Service, 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.

Title: Soil Survey of Mendocino County, Western Part, California

Geospatial_Data_Presentation_Form: text, table, map

Other_Citation_Details:

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.

 

This soil survey 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.

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).

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. Feature edges and descriptive

attributes of quadrangles in this survey are matched to those in

the "Mendocino County, Eastern Part and the Southwest Part of

Trinity County, California Soil Survey". Feature labels do not match.

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 miscellaneous

(nonsoil) 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 may not be indicated on the map.

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, 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, (current issue).

 

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 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 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 6 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.

Process_Step:

Process_Description: The annotation negatives (scribecoats) were

scanned at 500 dpi by the National Cartography and Geospatial Center

in Fort Worth, Texas. The scan files were delivered in record

length code (.rlc) format. The scanned files were converted

into Arcinfo, version 6.1.1 using the imagegrid and gridline com-

mands. Four control points corresponding to the four corners of the

7.5 minute quadrangle were used for registration during data con-

version. Map neatline development, labeling, edgematching and

vector conversion, and editing were done in Arcedit, version

6.l.l. The insets were merged into full 7.5 minute quadrangle

format. The data were transformed from scanner inches into

Universal Transverse Mercator (UTM), Zone 10. The data were

written to Digital Line Graph (DLG3), optional format, Arcinfo

version 7.0.4. Digitizing and quality control was performed by

the cartographic technician in the Map Compilation Unit, at the

Davis Natural Resources Conservation Service, under the super-

vision of the state soil scientist.

Process_Step:

Process_Description: The DLG-3 files were imported for verification in

ARC/INFO, Version 7.0.4 by cartographic technicians on staff at the

Montana Digitizing Unit in Bozeman, MT. ARCEDIT was used to correct

extra vertices, pseudo nodes, and label mismatches to establish an

exact join to quadrangles within the survey area. New DLG-3 files

were written. The DLG-3 files were forwarded to the National

Cartography and Geospatial Center in Ft. Worth, TX for archiving

and distribution.

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 Interpretations

Record database. This attribute database gives the proportionate

extent of the component soils and the properties for each soil. 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 soil Map Unit

Interpretations Record database consists of the following

relational tables:

codes (database codes) - stores information on all codes used

in the database

comp (map unit component) - stores information for soil map unit

components

compyld (component crop yield) - stores crop yield information

for soil map unit components

the soil map units. Table not populated.

hydcomp (hydric component information) - stores data related to

the hydric classification, criteria, landform, etc.

inclusn (map unit inclusion) - stores the names of soils

included in the soil map units

interp (interpretation) - stores soil interpretation ratings

(both limitation ratings and suitability ratings) for soil

map unit components

layer (soil layer) - stores characteristics of soil layers for

soil map unit components

mapunit (map unit) - stores information that applies to all

components of a soil map unit

mucoacre (map unit county acres) - stores the number of acres

for the map unit within a county

muyld (map unit yield) - stores crop yield information for the

soil map unit

for the county within the boundary of the soil survey area

ssarea (soil survey area) - stores information that will apply

to an entire soil survey area

taxclass (taxonomic classification) - stores the taxonomic

classification for soils in the database

windbrk (windbreak) - stores information on recommended

windbreak plants for soil map unit components. Table not populated.

wlhabit (wildlife habitat) - stores wildlife habitat information
