Metadata for the 108th CD Census TIGER/Line® Files can be found at http://www.census.gov/geo/www/tlmetadata/tl108cdmeta.txt.
Shapefiles were converted from the TIGER/Line®-Files using the TGR2SHP program available for free download from here. Please refer to the TGR2SHP User's Manual for further information.
The original TIGER/Line® data are not in a mapping projection even though most of the features were scanned directly from source maps that were in a projection. The North American Datum of 1983 (NAD83) is the coordinate datum used for the 48 contiguous states, the District of Columbia, Alaska, Puerto Rico, and the Virgin Islands of the United States. A North American Datum of 1983 (NAD83) projection has been defined for the State- and County-level shapefiles. A projection file is now included with the State- and County-level shapefiles.
