How are the TIGER/Line Shapefiles different from the TIGER/Line files?
With the modernization of the Master Address File (MAF) and Topologically Integrated Geographic Encoding and Referencing (TIGER) databases from our home-grown database to an Oracle relational database, the Census Bureau has decided to replace the TIGER/Line files, which were ASCII text format, with the new TIGER/Line Shapefiles. The shapefiles contain information similar to what was found in the TIGER/Line files. For detailed information about the contents of the latest version of the shapefiles, refer to the 2009 TIGER/Line Shapefiles Technical Documentation.
