Attribute Accuracy:

Attribute Accuracy Report: Accurate against Federal Information Processing Standards (FIPS), FIPS Publication 6-4 (for counties), FIPS 55-3 (for incorporated places and minor civil divisions/census county divisions), and FIPS Publication 5-2 (for states) 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.

Logical Consistency Report: The feature network of lines (as represented by Record Types 1 and 2) is complete for census purposes. Spatial objects in TIGER/Line belong to the "Geometry and Topology" (GT) class objects in the "Spatial DataTransfer 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, performed spatial data tests for logical consistency of the codes during the compilation of the original Census TIGER data 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 reflects the contents of the Census TIGER data base as of January 1, 1990. These American Indian / Alaska Native Areas boundary files contain all coordinates from the data in the TIGER data base (i.e., they are NOT generalized). The American Indian and Alaska Native entities are 1990 reservations and off-reservation trust lands recognized by the federal government, 1990 state reservations, and 1990 tribal statistical areas including tribal jurisdiction statistical areas (TJSAs), tribal designated statistical areas (TDSAs),and Alaska Native village statistical areas (ANVSAs). The boundaries for these entities are used for Census Bureau statistical data purposes and depict the data as it exists in the Census Bureau's TIGER geographic database. The boundaries are for Census Bureau statistical data collection and tabulation purposes only; their depiction and designation for statistical purposes does not constitute a determination of jurisdictional authority or rights of ownership/entitlement.
Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report: The information present in these files 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 material 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 1997 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 map 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 resources, 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 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.
