Superfund GIS - Soil thickness, permeability, texture, and classification in Tennessee

This dataset was developed for use with the Tennessee STATSGO data base as an
additional datafile. Each record in the datafile relates to a STATSGO MUID
number which is assigned to a polygon(s) in the STATSGO geographic coverage.
Four soil attributes were derived from the COMP and LAYER datafiles of STATSGO,
all of which are represented as percentages of the particular map unit's area.
By representing these properties as percentages, a four-color (CMYK) display
can be utilized to represent the properties more effectively than a single-color
or grayscale display.
