The U.S. Department of Agriculture, Soil
Conservation Service should be acknowledged as the data
source in products derived from these data.
STATSGO was designed primarily for regional, multicounty,
river basin, State, and multistate resource planning,
management, and monitoring. STATSGO data are not detailed
enough to make interpretations at a county level. This soil
survey product is not designed for use as a primary
regulatory tool in permitting or citing decisions, but may be
used as a reference source. The use of these data is not
restricted and may be interpreted by organizations, agencies,
units of government, or others; however, they are responsible
for its appropriate application. Federal, State, or local
regulatory bodies are not to reassign to the Soil
Conservation Service any authority for the decisions that
they make. The Soil Conservation Service will not perform
any evaluations of these maps for purposes related solely to
state or local regulatory programs.
When STATSGO data are overlayed with other data layers, such
as land use data, caution must be used in generating
statistics on the co-occurence of the land use data with the
soil data. The composition of the STATSGO map unit can be
characterized independently for the land use and for the soil
component, but there are no data on their joint occurrence at
a more detailed level. Analysis of the overlayed data should
be on a map polygon basis.
Additional political, watershed, or other boundaries may be
intersected with the soil data. Although the composition of
each political and watershed unit may be described in terms
of the STATSGO map units, information is not available to
assign the components to the boundary units with full
accuracy. As with the land use categories, the analysis
should be restricted to the classified components.
The approximate minimum area delineated is 625 hectares
(1,544 acres), which is represented on a 1:250,000-scale map
by an area approximately 1 cm by 1 cm (0.4 inch by 0.4 inch).
Linear delineations are not less than 0.5 cm (0.2 inch) in
width. The number of delineations per 1:250,000 quadrangle
typically is 100 to 200, but may range up to 400.
Delineations depict the dominant soils making up the
landscape. Other dissimilar soils, too small to be
delineated, are present within a delineation.
Digital enlargements 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.
Attribute data for some data elements may be incomplete or
missing. Where data are unavailable, a mask should be used
to exclude the area from analysis.
Digital data files are periodically updated. Files are
dated, and users are responsible for obtaining the latest
version of the data.
