Accurate against Federal information Processing Standards <br /> ( FIPS) , HIPS Publication 6-4, and FIPS-55 at the 100% level for the codes and base <br /> names . The remaining attribute information has been examined but has not been fully <br /> tested for accuracy. <br /> Logical-Consistency-Report : <br /> The feature network of lines (as represented by Record Types 1 and 2) is compete <br /> for census purposes . Spatial objects in TIGER/ Line belong to the "Geometry and <br /> Topology" ( GT) class of objects in the "Spatial Data Transfer Standard" (SDTS ) <br /> HIPS Publication 173 and are topologically valid . Node/geometry and topology <br /> ( GT) -polygon /chain relationships are collected or generated to satisfy topological <br /> edit requirements . These requirements include : <br /> * Complete chains must begin and end at nodes . <br /> ` Complete chains must connect to each other at nodes . <br /> * Complete chains do not extend through nodes . <br /> Completeness-Report: <br /> Data completeness of the TIGER / Line files reflects the contents of the Census TIGER <br /> data base at the time the TIGER/ Line files ( Redistricting Census 2000 version ) were <br /> b created . <br /> Position al_Accuracy: <br /> Horizontal-Positional-Accuracy : <br /> Horizontal-Positional-Accuracy-Report: <br /> The information present in these files is provided for the purposes of statistical <br /> analysis and census operations only . Coordinates in the TIGER/ Line files have six <br /> implied decimal places , but the positional accuracy of these coordinates is not as <br /> great as the six decimal places suggest . The positional accuracy varies with the <br /> source materials used , but generally the information is no better than the established <br /> national map Accuracy standards for 1 : 100, 000-scale maps from the U .S . Geological <br /> M Survey ( USGS ) : thus it is NOT suitable for high- precision measurement applications <br /> such as engineering problems , property transfers , or other uses that might require <br /> highly accurate measurements of the earth 's surface . The USGS 1 : 100, 000-scale maps <br /> met national map accuracy standards and use coordinates defined by the North <br /> American Datum , 1983 , <br /> Lineage : <br /> Source Information : <br /> Source Citation : <br /> Citation Information : <br /> Originator: <br /> U .
