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.
