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.
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.

Information Content: The BTS standard format for
spatial data is an interim format for distributing
National Transportation Atlas Databases pending
final approval of an SDTS Transportation Network
Profile (TNP). The BTS standard format consists
of a linked set of ASCII fixed record length
files. File formats and data dictionary for the
BTS standard format are described in the document,
'National Transportation Atlas Data Dictionary and
Database Formats', September 1995. Copies of this
documentation are distributed with each National
Transportation Atlas Database.
