TIGER and Census Bureau Data in a GIS: A Powerful Combination for Civil Engineersby Robert W. Marx, U.S. Dep of Commerce, Washington, United States,
Abstract: TIGER is the acronym the Census Bureau crated to identify its computerized geographic support system: the Topologically Integrated Geographic Encoding and Referencing System. Although the TIGER data base is not a geographic information system (GIS) in the traditional context, it has become a critical component of many GISes. The wealth of digital spatial data available through an emerging concept called the National Spatial Data Infrastructure (NSDI) will change forever the ways in which engineers process such information. Using a GIS, the TIGER data base, and the numerous geographically distributed data sets available as part of the NSDI, civil engineers will be able to quickly integrate map information, statistical data, and a wide variety of other geographically-referenced data needed for engineering analysis as part of the project planning process. By having all this information readily available, the public will receive a wonderful return on its investment.
