Data_Quality_Information:

  Attribute_Accuracy_Report:
        School district numbers were copied directly from the 1992
        TIGER files.  Names were edited from the Census Bureau
        look-up tables to eliminate all caps, notation that each
        district is an elementary district, and to expand
        abbreviations.  The names have not been thouroughly
        double-checked. 
  Completeness_Report:
        Data set is complete 
  Horizontal_Positional_Accuracy_Report:
        Approximate horizontal accuracy is 51 meters, assuming
        source data meets National Map Accuracy Standards. 
  Vertical_Positional_Accuracy_Report:
        NONE

          were school district boundaries.
  Process_Step
    Process_Description:
      Convert TIGER files to Arc/Info format and project them
      from geographic coordinates to Albers.  See tiger92.aml
