Maf/Tiger Accuracy Improvement Program

In 1980's, the Census Bureau developed the Topologically Integrated Geographic Encoding and Referencing system (TIGER) to support our mapping needs for the 1990 Census. In the 1990's, we developed the Master Address File (MAF) as a complete and current list of all addresses and locations where people live or work, covering an estimated 115 million residences, as well as 60 million businesses and other structures in the U.S. The 2000's will be the decade of the MAF/TIGER Accuracy Improvement. We plan to improve the coordinate accuracy of TIGER to at least 7.6 meters CE95 for every county in the U.S. In this session, we will discuss the methodology for MAF/TIGER Accuracy, the expansion of partnership programs, and our testing of mobile computing devices with GPS for Census 2010.
