                               in the format SSS-TTT-CCCCC-GGGGG-IIIII, where
                               SSS identifies the portion of the study area:
                               NSA, SSA, REG, TRN, and TTT identifies the cover
                               type for the site, 999 if unknown, and CCCCC is
                               the identifier for site, exactly what is means
                               will vary with site types, GGGGG is the group
                               associated with the sub-site instrument, e.g.
                               HYD06 or STAFF, and IIIII is the identifier for
                               sub-site, often this will refer to an instrument.

                               latitude coordinate at the site.  This is used to
                               reflect the precision of the site coordinates 
                               derived by GPS.

Minimum Data Value -- The minimum value found in the column.
Maximum Data Value -- The maximum value found in the column.
Missng Data Value  -- The value that indicates missing data. This is used to
                      indicate that an attempt was made to determine the
                      parameter value, but the attempt was unsuccessful.
Unrel Data Value   -- The value that indicates unreliable data.  This is used
                      to indicate an attempt was made to determine the
                      parameter value, but the value was deemed to be
                      unreliable by the analysis personnel.
Below Detect Limit -- The value that indicates parameter values below the
                      instruments detection limits.  This is used to
                      indicate that an attempt was made to determine the
                      parameter value, but the analysis personnel determined
                      that the parameter value was below the detection
                      limit of the instrumentation.
Data Not Cllctd    -- This value indicates that no attempt was made to
                      determine the parameter value.  This usually
                      indicates that BORIS combined several similar but
                      not identical data sets into the same data base table
                      but this particular science team did not
                      measure that parameter.

Blank -- Indicates that blank spaces are used to denote that type of value.
N/A   -- Indicates that the value is not applicable to the respective column.
None  -- Indicates that no values of that sort were found in the column.
