                   Data Quality Information

 

Attribute Accuracy

  Attribute_Accuracy_Report: Attributes for the 106th

      Congressional District data set were created in a consistent

      manner using similar tolerances. 

 

  Logical_Consistency_Report: All node-link and polygon

      topological relationships were created and verified using

      ARC/INFO a Geographic Information System.  The unique

      identifiers were verified using ARC/INFO. (The data was

      then converted to a shapefile format.)

 

Completeness_Report: This data set is composed of the 435

     Districts having voting representation plus seven districts

     without voting rights including the District of Columbia and

     US territories.

 

Positional Accuracy

  Horizontal Positional Accuracy

    Horizontal_Positional_Accuracy_Report: The Congressional

        District data set was created from TIGER/Line data

        having a nominal scale of 1:100,000.
