Description:
Abstract:
The 1998 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, 1998 legal boundaries. The 1998 TIGER/Line files consist of line segments representing physical features and governmental and statistical boundaries.
Purpose:
The 1998 TIGER/Line files were originally produced for use by the states participating in the Census 2000 Redistricting Data Program, Phase 2, the Voting District project (VTDP) to submit their voting districts to the Census Bureau.

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.
Completeness Report: Data completeness of the TIGER/Line files reflects the contents of the Census TIGER data base at the time the TIGER/Line files (1998 version) were created.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional 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 1998 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 1990 census map sheets; the 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.

Other Citation Details:
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 Bureau of the Census
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.
