IDENTIFICATION INFORMATION
Description: Soil Survey Geographic (SSURGO) database for
Cochise County, Arizona, Douglas-Tombstone Part
Abstract: This data set is a digital soil survey and
generally is the most detailed level of soil
geographic data developed by the Natural
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 National Soil
Information System relational database, which
gives the proportionate extent of the
component soils and their properties.

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.
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.

DATA QUALITY INFORMATION
Software: N/A
Operating_System: N/A
Path_Name:
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 digitalized
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.
The features and feature labels in this soil
survey are not edge matched to features in the
Santa Cruz and Parts of Cochise and Pima Counties,
Arizona survey, Wilcox Area, Arizona survey, San
Simon Area, Arizona, Parts of Cochise, Graham and
Greenlee Counties survey due to age or
conditions noted in the correlation document,
published report, or other archived documentation.
The soil survey boundary is considered to be the
soil boundary for the Santa Cruz and Parts of
Cochise and Pima Counties, Arizona survey, Wilcox
Area, Arizona survey, San Simon Area, Arizona,
Parts of Cochise, Graham and Greenlee Counties
Soil Survey.
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 carries out in sufficient detail to
name map units and to identify accurately and
consistently areas of about 40 acres for order 3
mapping and about 6 acres for order 2 mapping.
Horizontal_Positional_Accuracy: 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.
Vertical_Positional_Accuracy: N/A
Attribute_Accuracy: 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).

Process_Step:
Process_Description: Field procedures for the second and third order soil
survey included plotting of soil boundaries
determined by field observation and interpretation
of remotely sensed data. 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 sampled the soils, analyzed samples in the
laboratory, and statistically analyzed the data. The
classification and map unit names were finalized at the
final correlation in June, 2000.

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 National Soil Information
System 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 National Soil
Information System 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 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 features tables. It
includes a feature label, feature name, and feature
description for each special and ad hoc feature in
the survey area.
