- Abstract TIGER, TIGER/Line, and Census TIGER are registered trademarks of the Bureau of the Census. The Redistricting Census 2000 TIGER/Line
files are an extract of selected geographic and cartographic information from the Census TIGER data base. The geographic
coverage for a single TIGER/Line file is a county or statistical equivalent entity, with the coverage area based on January
1, 2000 legal boundaries. A complete set of Redistricting Census 2000 TIGER/Line files includes all counties and statistically
equivalent entities in the United States and Puerto Rico. The Redistricting Census 2000 TIGER/Line files will not include
files for the Island Areas. The Census TIGER data base represents a seamless national file with no overlaps or gaps between
parts. However, each county-based TIGER/Line file is designed to stand alone as an independent data set or the files can
be combined to cover the whole Nation. The Redistricting Census 2000 TIGER/Line files consist of line segments representing
physical features and governmental and statistical boundaries. The Redistricting Census 2000 TIGER/Line files do NOT contain
the ZIP Code Tabulation Areas (ZCTAs) and the address ranges are of approximately the same vintage as those appearing in the
1999 TIGER/Line files. That is, the Census Bureau is producing the Redistricting Census 2000 TIGER/Line files in advance
of the computer processing that will ensure that the address ranges in the TIGER/Line files agree with the final Master Address
File (MAF) used for tabulating Census 2000. The files contain information distributed over a series of record types for the
spatial objects of a county. There are 17 record types, including the basic data record, the shape coordinate points, and
geographic codes that can be used with appropriate software to prepare maps. Other geographic information contained in the
files includes attributes such as feature identifiers/census feature class codes (CFCC) used to differentiate feature types,
address ranges and ZIP Codes, codes for legal and statistical entities, latitude/longitude coordinates of linear and point
features, landmark point features, area landmarks, key geographic features, and area boundaries. The Redistricting Census
2000 TIGER/Line data dictionary contains a complete list of all the fields in the 17 record types.
- Purpose In order for others to use the information in the Census TIGER data base in a geographic information system (GIS) or for other
geographic applications, the Census Bureau releases to the public extracts of the data base in the form of
TIGER/Line files. Various versions of the TIGER/Line files have been released; previous versions include the 1990 Census
TIGER/Line files, the 1992 TIGER/Line files, the 1994 TIGER/Line files, the 1995 TIGER/Line files, the 1997 TIGER/Line files,
the 1998 TIGER/Line files, and the 1999 TIGER/Line files. The Redistricting Census 2000 TIGER/Line files were originally
produced to support the Census 2000 Redistricting Data Program.

- Maintenance and Update Frequency
TIGER/Line files are extracted from the Census TIGER data base when needed for
geographic programs required to support the census and survey programs of the
Census Bureau. No changes or updates will be made to the Redistricting Census
2000 TIGER/Line files. Future releases of TIGER/Line files will reflect updates
made to the Census TIGER data base and will be released under a version numbering
system based on the month and year the data is extracted.

Data Quality Information
- Attribute Accuracy Report

- Report
Accurate against Federal information Processing Standards
(FIPS), FIPS Publication 6-4, and FIPS-55 at the 100% level for the codes and base
names. The remaining attribute information has been examined but has not been fully
tested for accuracy.

- Report The information present in these files is provided for the purposes of statistical analysis and census operations only. Coordinates
in the TIGER/Line files have six implied decimal places, but the positional accuracy of these coordinates is not as great
as the six decimal places suggest. The positional accuracy varies with the source materials used, but generally the information
is no better than the established national map Accuracy standards for 1:100,000-scale maps from the U.S. Geological Survey
(USGS); thus it is NOT suitable for high-precision measurement applications such as engineering problems, property transfers,
or other uses that might require highly accurate measurements of the earth's surface. The USGS 1:100,000-scale maps met national
map accuracy standards and use coordinates defined by the North American Datum, 1983. For the contiguous 48 States, the cartographic
fidelity of most of the Redistricting Census 2000 TIGER/Line files, in areas outside the 1980 census Geographic Base File/Dual
Independent map Encoding (GBF/DIME) file coverage and selected other large metropolitan areas, compare favorable with the
USGS 1:100,000-scale maps. The Census Bureau cannot specify the accuracy of features inside of what was the 1980 GBF/DIME-File
coverage or selected metropolitan areas. The Census Bureau added updates to the TIGER/Line files that enumerators annotated
on maps sheets prepared from the Census TIGER data base as they attempted to traverse every street feature shown on the Census
2000 map sheets; the Census Bureau also made other corrections from updated map sheets supplied by local participants for
Census Bureau programs. The locational accuracy of these updates is of unknown quality. In addition to the Federal, State,
and local sources,
portions of the files may contain information obtained in part from maps and other materials prepared by private companies.
Despite the fact the TIGER/Line data positional accuracy is not as high as the coordinate values imply, the six-decimal place
precision is useful when producing maps. The precision allows features that are next to each other on the ground to be placed
in the correct position, on the map, relative to each other, without overlap.

- Logical Consistency Report
The feature network of lines (as represented by Record Types 1 and 2) is compete
for census purposes. Spatial objects in TIGER/Line belong to the "Geometry and
Topology" (GT) class of objects in the "Spatial Data Transfer Standard" (SDTS)
FIPS Publication 173 and are topologically valid. Node/geometry and topology
(GT)-polygon/chain relationships are collected or generated to satisfy topological
edit requirements. These requirements include:
* Complete chains must begin and end at nodes.
* Complete chains must connect to each other at nodes.
* Complete chains do not extend through nodes.
* Left and right GT-polygons are defined for each complete chain element and are
consistent throughout the extract process.
* the chains representing the limits of the files are free of gaps.
The Census Bureau performed automated tests to ensure logical consistency and limits
of files. All polygons are tested for closure. The Census Bureau uses its internally
developed Geographic Update System to enhance and modify spatial and attribute data in
the Census TIGER data base. Standard geographic codes, such as FIPS codes for states,
counties, municipalities, and places, are used when encoding spatial entities. The
Census Bureau performed spatial data tests for logical consistency of the codes during
the compilation of the original Census TIGER data base files. Most of the Codes
themselves were provided to the Census Bureau by the USGS, the agency responsible for
maintaining FIPS 55. Feature attribute information has been examined but has not been
fully tested for consistency.

-
- Process Description In order for others to use the information in the Census TIGER data base in a GIS or for other geographic applications, the
Census Bureau releases periodic extracts of selected information from the Census TIGER data base, organized as topologically
consistent networks. Software (TIGER DB routines) written by the
Geography Division allows for efficient access to Census TIGER system data. TIGER/Line files are extracted from the Census
TIGER data base by county or statistical equivalent area. Census TIGER data for a given county or statistical equivalent
area is then distributed among 17 fixed length record ASCII files, each one containing attributes for either line, polygon,
or landmark geographic data types. The Census Bureau has released various versions of the TIGER/Line files since 1988, with
each version having more updates (feature and feature names,
address ranges and ZIP Codes, coordinate updates, revised field definitions, etc.) than the previous version.
