and Development - TIGER
- 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. More ...
