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.

In order for others to use the information in the Census TIGER
database in a GIS or for other geographic applications, the
Census Bureau releases periodic extracts of selected information
from the Census TIGER database, 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 database by county or statistical equivalent
area.  Census TIGER data for a given county or statistical
equivalent area is then distributed among 19 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.

Technical_Prequisites: The 2002 TIGER/Line files contain
geographic data only and do not include display or mapping software
or statistical data.  For information on how to use the TIGER/Line
data with a specific software package users should contact the
company that produced the software.  A list of vendors who have
developed software capable of processing TIGER/Line files can be
found by visiting http://www.census.gov/geo/www/tiger.  The
TIGER/Line files are provided in ASCII text format only.  Users
are responsible for converting or translating the files into a
format used by their specific software package.
