Soil Survey Geographic (SSURGO) data by county for portions of Wyoming (approximate scale 1:24,000)

SSURGO depicts information about soil features on or near the surface of the
Earth. These data were collected as part of the National Cooperative Soil
Survey.

This data set is a digital soil survey and is the most detailed level of soil
geographic data developed by the National Cooperative Soil Survey. The
information was collected by digitizing maps, by compiling information onto a
planimetric correct base and digitizing, or by revising digitized maps using
remotely sensed and other information.

SSURGO soil data currently exists for Wyoming for all or part of the following
counties: Albany, Laramie, Platte, Natrona, Campbell, Washakie counties (as of
October, 2000)

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. Sometimes a special soil features layer (point and
line features) is included. 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 Map Unit Interpretations Record
relational data base, which gives the proportionate extent of the component
soils and their properties.
