The files in this directory are not the "Official" Soil Survey Geographic
(SSURGO) data developed by the USDA - Natural Resource Conservation
Service (NRCS). They are derived from the SSURGO data by converting
the existing data from one form to another. The principal software
used for conversion was Arc/Info. The original spatial data were in
Optional Digital Line Graph format with coordinates registered to either
the North American Datum of 1983 or the North American Datum of 1927.
The original attribute (relational) data were in variable-length tab
delimited ASCII table format.

While care has been taken to preserve the quality of the data;
transformation, geographic, mathematical, format and structure errors
may have been introduced to the data.  Because it is necessary to
ensure that the data are kept current, the data sets will continue
to change.
