Minimum Maximum Missng Unrel Below Data Data Data Data Data Detect Not Column Name Value Value Value Value Limit Cllctd -------------------------------------------------------------------------------- PROVINCE ALBERTA SASKATCHEWAN None None None None MAP_NAME N/A N/A None None None None MAP_SUBJECT N/A N/A None None None None SCALE 1:1,000,000 1:12,500 None None None None MAP_FORM N/A N/A None None None None MAP_SOURCE N/A N/A None None None None NW_LONGITUDE -112.00002 -96.00016 None None None None NE_LONGITUDE -110.00099 -90.00001 None None None None SE_LONGITUDE -110.0009 -90.00006 None None None None SW_LONGITUDE -112.00003 -96.00016 None None None None NW_LATITUDE 50.00000 60.00022 None None None None NE_LATITUDE 49.25003 60.00022 None None None None SE_LATITUDE 48.99998 59.00019 None None None None SW_LATITUDE 48.99998 59.0002 None None None None -------------------------------------------------------------------------------- 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. -------------------------------------------------------------------------------- 7.4 Sample Data Record PROVINCE,MAP_NAME,MAP_SUBJECT,SCALE,MAP_FORM,MAP_SOURCE,NW_LONGITUDE, NE_LONGITUDE,SE_LONGITUDE,SW_LONGITUDE,NW_LATITUDE,NE_LATITUDE,SE_LATITUDE, SW_LATITUDE 'MANITOBA','T 75 R04 W','FC AUX','1:15,840','PAPER','MNR-FB',-98.08332, -97.92575,-97.92809,-98.08531,55.54781,55.54653,55.46055,55.46182 'MANITOBA','T 75 R05 W','FC AUX','1:15,840','PAPER','MNR-FB',-98.23855, -98.08131,-98.08332,-98.24021,55.5478,55.54672,55.46055,55.46162
