| Abstract: | USSOILS is an Arc 7.0 coverage containing hydrology-relevant information
for 10,498 map units covering the entire conterminous United States.
The coverage was compiled from individual State coverages contained in
the October 1994 State Soil Geographic (STATSGO) Data Base produced on
CD-ROM. The geo-dataset USSOILS.PAT relates (on the basis of a map unit
identifier) the 10,498 map units to 78,518 polygons. The scale of the
geo-dataset is 1:250,000. The INFO attribute table USSOILS.MUID_ATTS
contains selected variables from the STATSGO data set for 10,501 map
units (an extra 3 map units are contained in the attribute table that
are not in the geo-dataset - see the ‘Procedures‘ section below),
including: the map unit identifier, a 2-character state abbreviation,
available water capacity of the soil, percent clay in the soil, the
actual k-factor used in the water erosion component of the universal
soil loss equation, the organic material in soil, soil permeability,
cumulative thickness of all soil layers, hydrologic characteristics of
the soil, quality of drainage, surface slope, liquid limit of the soil,
share of a map unit having hydric soils, and the annual frequency of
flooding. To facilitate mapping the attribute data, the narrative
section below contains instructions for transferring the information
contained in the attribute table USSOILS.MUID_ATTS to the polygon
attribute table USSOILS.PAT.
