In 1981 the U.S. Bureau of the Census set a goal to automate the full range of cartographic and geographic processes in time to serve the data collection, tabulation, and dissemination needs of the 1990 decennial census of the United States. The Geography Division designed and built with the assistance of the U.S. Geological Survey the Topologically Integrated Geographic Encoding and Referencing (TIGER) data base to meet this goal. The Census Bureau will make available several nationwide graphic products from this data base. These products include digital cartographic data base extract files as well as the more traditional map products. These extract files will make available to the transportation planners a consistent set of digital nationwide networks and linkages to census data.
