Description
A characterization of the data, including its intended use and limitations.
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 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.

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.

+ Data Quality and Accuracy Information
General
Information about the fidelity of relationships, data quality and accuracy tests, omissions, selection criteria, generalization, and definitions used to derive the data.
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 Soil Survey of Connecticut is bordered on the north by the State
of Massachusetts; to the east by the State of Rhode Island; to the
south by Long Island Sound and to the west by the State of New York.

The Soil Survey of the State of Connecticut (CT600) is edge matched
to all of the adjacent SSURGO certified soil surveys:
MA003  -  Berkshire County, Massachusetts
MA607  -  Hampden County, Massachusetts, Central Part
MA608  -  Hampden and Hampshire Counties, Massachusetts, Western Part
MA610  -  Hampden and Hampshire Counties, Massachusetts, Eastern Part
MA615  -  Worcester County, Massachusetts, Southern Part
NY027  -  Dutchess County, New York
NY059  -  Nassau County, New York
NY079  -  Putnam County, New York
NY103  -  Suffolk County, New York
NY119  -  Westchester County, New York
RI600  -  State of Rhode Island

The soil survey area boundaries match.

Feature edges in this soil survey are not matched to those in
Westchester County, New York, Putnam County, New York, Dutchess County,
New York, Berkshire County, Massachusetts, Hampden and Hampshire
Counties, Western Part, Massachusetts, Hampden and Hampshire Counties,
Eastern Part, Massachusetts, and the State of Rhode Island soil
surveys. Acceptable joins as outlined in Revisions to the National
Soils Handbook, dated 8/27/97 were achieved with all of the surrounding
surveys. Feature labels do not always match, but soil interpretations
are similar enough to achieve an acceptable join. Map units in this
survey that join map units in adjacent surveys share a common
component, common stoniness class, and common slopes. Differences
across state lines occurred relative to map unit design and scales
used in mapping. Typically, map units designed for a scale of 1:12000
are comprised of consociations, complexes, and undifferientiated
units. Complexes and undifferentiated units are comprised of two or
more components. In areas where these complexes or undifferentiated
units join a consociation (one named component), this is an acceptable
join if the adjoining map units share a common component, common
stoniness class, and common slopes thus resulting in similar soil
interpretations. An exception is made for adjoining organic soils,
which are considered to match. The scale is used to determine how much
detail can be shown on the map. To deal with the limitations of scale,
some map units were designed to cover two stoniness classes and two
slope classes. Where map units that are very stony join extremely
stony, they will be considered an acceptable join since each stoniness
class is commonly an inclusion in the other during the mapping process.
Non-stony map units must match non-stony map units. Overlapping slope
ranges will be considered as matching.
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 may
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
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 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 3 acres.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
Attribute accuracy report:
The 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).
Positional Accuracy
Accuracy of the positional aspects of the data.
Horizontal 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.

Process description:
Field procedures for the second order soil
survey included plotting of soil boundaries determined by field
observation and by 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. The classification and map unit names were
progressively reviewed December 1993 and August 2001.

Process description:
Hydrography was transferred from 1:15840 acetates
to the 1:15840 orthophotographs as a reference only for soil
delineations. This data was not digitized from the orthophotographs,
but digitally subset from USGS DLGs. Field maps and published atlas
sheets were ratioed to approximately 1:15840 when necessary and then
manually compiled using imagery transfer techniques to 1:15840
orthophotograph enlargements. Slight adjustments were made to soil
boundaries near hydrography for clarity. These adjustments occurred
along narrow floodplains, shorelines, and other areas of fluctuating
water levels. Water bodies for Litchfield County were adjusted from
the aerial photography during remapping. Special soil features were
compiled on film overlays and manually digitized using GRASS 4.1.3
and ArcInfo 8.2. Soil delineations were digitized using one of the
following procedures:

1) Soil delineations were inked on 7mil overlays and scanned at
300dpi. Utilizing ProVec software, data were edited and converted to
vector format. Data was then imported into ARC/INFO 3.4D and
georeferenced to Connecticut State Plane feet - NAD 27. Each
quadrangle has sixteen tics, therefore, data was transformed by
ninths maintaining Root Mean Square (RMS) less than .003. The
hydrography template was imported, vectors edited and labels created.

2) Soil delineations were manually digitized using ARC/INFO 3.2.1.
Data were registered in Connecticut State Plane coordinates
maintaining RMS less than .003. Weed and fuzzy tolerances maintained
at 3. Data were transferred to ARC/INF0 6.0 for approximate
edgematching and label editing, exported to DLGs, and imported to
GRASS 4.1.3. Data was projected to UTM coordinates NAD 27 and edited
for node to node edgematching.

Soil special features were manually digitized by using one of the
following software products, GRASS 4.1.3 or ArcInfo 8.2. Compilation,
digitizing, and quality control were performed by soil scientists and
cartographic technicians at the Connecticut Natural Resources
Conservation Service. Digital scanning and vector conversion was
performed by private contractor. Digital editing was performed at
the Connecticut Natural Resources Conservation Service and the
Connecticut Department of Environmental Protection - Natural
Resources Center. Digital soils delineations were visually verified
using background digital orthophotograph imagery at 1:12000 to ensure
accuracy at this scale.  Organic soils, bedrock controlled soils and
other easily identified features were utilized to ensure vertical
integration and accurate soil delineation placement. Digital review
for adherence to SSURGO standards was performed by the Missouri NRCS
Digitizing Unit. Edits were made in ArcEdit. The survey area boundary
was replaced with the boundary arcs from adjacent surveys, where
possible. A new ARC/INFO coverage reflecting these edits was produced
and reviewed for adherence to SSURGO standards by Missouri NRCS
Regional Digitizing Unit staff. The certified data were uploaded to
the Soil Data Warehouse for archiving and distribution.

Edits were made during the spring and summer of
2014 as part of the MLRA 144A - Spatial Edits to CT600 - Phase I?
MLRA update project.  The purpose of this project was to investigate
map units with stoniness phases mapped in MLRAs 144A, 144B, and 145
on a per request basis for site visits related to the Prime and
Important farmland designations for the FRPP (Farm and Ranch Land
Protection Program), CT Purchase of Development Rights (PDR) Program,
and Farmland Policy Protection Act (FPPA). Component properties were
documented via on-site visits to Farm Bill cooperator land.  Map
units were then re-correlated to map units with stoniness and/or
slope phases that agree with the on-site field notes.  A small number
of spatial edits to polygon boundaries were made to identify the new
boundaries between stony and stone-cleared areas.  The data were checked with
the SSURGO Evaluation scripts provided by U.S. Department of Agriculture,
Natural Resources Conservation Service. The shapefiles were then uploaded
to the soil data warehouse for archival and distribution.

Coastal delineations of SSURGO map unit 301 (Beaches-Udipsamments complex,
coastal) from CT600 were evaluated using the following basemap materials: Bing
orthophotography and Surficial Materials Map of Connecticut, Stone and others,
1992.  Coverage percentages of beaches, unvegetated dune land, vegetated dune
soils, fill soils (unnaturally surface morphometry/topography and deep green
vegetation are primary indicators of additions of fill), and urban land were
visually estimated to determine new map unit assignments.  The Surficial
Materials Map of Connecticut was also used to interpret whether areas of map unit
301 were associated with natural coastal landforms or artificial fill.  Slope
phases were determined using the SSURGO map units as zone features and generating
zonal statistics using a percent slope raster created from 10m NED elevation
data.  Min, max, median, mean, majority (i.e., mode) and standard deviation
values were used to assign slope phases.  Map unit delineation nodes were not
edited during this phase of updates to dune land areas.
