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 5 acres.

Process_Description:
Columbia County had a previously published
soil survey, 1989, at 1:15840 scale. An evaluation was made
of the soil survey in 1995. It was determined that the soil map
unit delineations and map unit components were accurate.
Source_Used_Citation_Abbreviation: SCS1
Process_Date: 1995
Process_Step:
Process_Description:
Soil map unit delineations were manually
scribed from the publication annotation overlay to a 7.5 multiple
orthophoto quadrangles. Errors from the published soil
survey were corrected and map unit boundaries were refined
as needed to the orthophoto film positive.

Process_Step:
Process_Description:
The one-half quadrangle soil delineation
scribe coats were raster scanned by Midwest Graphics, Milwaukee,
Wisconsin at 250 dpi on an Intergraph Anatech scanner in rlc
format. Four control points corresponding to the four
corners on the 7.5 minute quadrangles were used for registration
during data collection. The processing, raster editing, map
neatline development, labeling, edge matching, vector conversion
and editing were done in LT4X Version 4.13 at U.S. Department of
Agriculture, Natural Resources Conservation Service, Wisconsin
Digitizing Unit, Madison, Wisconsin. The county borders were
manually digitized from the USGS 7.5 minute topographic quadrangles
in LT4X Version 4.02 on a Sun UNIX Workstation and exported and
snapped together using GRASS Version 4.13 and then imported back
into LT4X. The special soil features were manually digitized from
the 7.5 minute orthophoto quadrangles in LT4X at a resolution of at
least 0.01 inch. Check plots of the soils and special features data
were reviewed by a soil scientist and cartographic staff at the
Wisconsin Digitizing Unit, Madison, Wisconsin. The soils and
special features data were run through a series of LT4X macros for
correctness and completeness. These macros smoothed out and
thinned out linework, added nodes for every 3000 vertices, added
corner nodes and snapped nodes across the neatlines. The special
features data were run through an additional LT4X macro. The
digital soils and special features data were then exported as
Digital Line Graph-3 Optional format files in LT4X. The DLG-3
Optional format files were evaluated with the October 1998 ARC/INFO
SSURGO Evaluation AMLs provided by U.S. Department of Agriculture,
Natural Resources Conservation Service, National Cartography and
Geospatial Center, Fort Worth, Texas. Upon successful completion
of the SSURGO Evaluation, the DLGs were rewritten from ARC/INFO
Version 7.11. The ARC/INFO version DLGs were rechecked with the
October 1998 ARC/INFO SSURGO Evaluation AMLs provided by National
Cartography and Geospatial Center, Fort Worth, Texas. The DLGs
were processed with the October 1998 archiving AMLs provided by
National Cartography and Geospatial Center, Fort Worth, Texas.

The Michigan Digitizing Unit (MIDU) staff downloaded the SSURGO data
for Columbia County, New York and the adjacent surveys from the Soil
Data Warehouse (SDW). The MIDU staff checked the spatial data with
the ARCGIS Version 9.2 software. To remove excess vertices, the soil
boundaries were generalized at a 0.5 meter tolerance. The boundaries
of this soil survey were adjusted to match the adjacent soil surveys
at the 0.1 meter tolerance. After the soil survey was edited, the
area, line and point feature classes were converted to ARC/INFO
coverages and exported as e00 files. The seamless coverages were
checked using the July 2009 SSURGO Evaluation AML programs. The
labels in the spatial data matched the symbols in the mapunit table
from NASIS. Upon successful completion of the SSURGO Evaluation,
the county coverages, feature file and the metadata were
