| description:

This data set consists of general soil association units. It was
developed by the National Cooperative Soil Survey and supersedes
the State Soil Geographic (STATSGO) data set published in 2006.
It consists of a broad based inventory of soils and nonsoil areas
that occur in a repeatable pattern on the landscape and that can
be cartographically shown at the scale mapped. The data set was
created by generalizing more detailed soil survey maps. Where more
detailed soil survey maps were not available, data on geology,
topography, vegetation, and climate were assembled, together with
Land Remote Sensing Satellite (LANDSAT) images. Soils of like areas
were studied, and the probable classification and extent of the soils
were determined.
Map unit composition was determined by transecting or sampling areas
on the more detailed maps and expanding the data statistically to
characterize the whole map unit.
This data set consists of georeferenced vector digital data and
tabular digital data. The map data were collected in 1-by 2-degree
topographic quadrangle units and merged into a seamless national
data set. It is distributed in state/territory and national extents.
The soil map units are linked to attributes in the National Soil
Information System data base which gives the proportionate extent of
the component soils and their properties. |

The U.S. Department of Agriculture, Natural Resources Conservation
Service should be acknowledged as the data source in products
derived from these data. Hardcopies utilizing these data shall
clearly indicate their source. User agrees not to misrepresent these
data, nor to imply that changes made were approved by the Natural
Resources Conservation Service.
The Digital General Soil Map of U.S. was designed primarily for
regional, multicounty, river basin, State, and multistate resource
planning, management, and monitoring. 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 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.
When data from the Digital General Soil Map of U.S. 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 soil 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
soil 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).
The approximate minimum area delineated for Alaska is 2,500 hectares
(6,176 acres), which is represented on a 1:5000,000-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 data 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.
Data values for some data elements may be incomplete or missing.
Where data are unavailable, a mask should be used to exclude the
area from analysis.
The spatial and tabular data used to create this product are
periodically updated. Data are versioned, and users are responsible
for obtaining the latest version of the product. |
