The Census Bureau, however, was faced with the challenge of matching the addresses on the re- sponses to a map, so that the spatial distributions of the responses could be analyzed. To meet this challenge, the Census Bureau developed a system known as Dual Independent Map Encoding (DIME) which allowed.

    beginning, the database was hosted on the mainframe computer and was patterned after the US Census Bureaus GBF/DIME (Geographic Base File using Dual Independent Map Encoding) technology. Earlier applications of the file included address-matching voters addresses for the purpose of assigning election district and precinct codes to voter records.   The Census Use Study, a small-area data research group sponsored by the Census Bureau from to , was instrumental in creating and diffusing knowledge about a system that represented map features numerically for processing by a computer to create a geographic base file (U.S. Bureau of the Census ).

Bureau mathematician James Corbett developed a method to use Geographic Base Files (GBF, a map in machine-reading form) to encode map features into data files.

Publications relating to census mapping activities and the origin and use of the census tract,and listing U.S. minor civil division areas and giving their derivations, Training manuals for reading census maps and aerial photographs, and describing enumeration districts, The approach was called Dual Independent Map Encoding (DIME) and provided a major breakthrough by using topology in its database design.

This work was part of New Haven Census Use Project, looking for innovative ways to use digital Census data to deliver useful product. Somewhat earlier, the Census Bureau of the USA had used concepts from the field of topology to organize the data for the street segments of urban areas, via the line segment or DIME structure as used for the creation of digital files, officially called the GBF/DIME (Geographic Base File/Dual Independent Map Encoding) System (Figure ).Designed to help produce maps for field enumerators and.

Also around this time, the U.S. Census Bureau began the ambitious GBF-DIME (Geographic Base Files and Dual Independent Map Encoding) project, which was used to create digitized street maps for all cities in the United States during the census (Mark, Chrisman, Frank, McHaffie, & Pickles, ).

TIGER Files (Topologically Integrated Geographic Encoding and Referencing) – census-type data. A geographic information system (GIS) is a conceptualized framework that provides the ability to capture and analyze spatial and geographic data.

GIS applications (or GIS apps) are computer-based tools that allow the user to create interactive queries (user-created searches), store and edit spatial and non-spatial data, analyze spatial information output, and visually share the results of.

The Census Bureau's involvement in geographical data processing began with the New Haven Census Use Study in and led to the Dual Independent Map Encoding (DIME) scheme that featured data encoding for census areas and experimental computer-generated maps of census data [Schw73].
