DIME is the abbreviation for dual independent map encoding. This is a digital map format developed by the U.S. Bureau of the Census for population census. DIME format was superseded byTIGER format in the 1990 census.
DIME - Dual Independent Map Encoding Provides vector data such as streets to census data addresses. Superseded by Topologically Integrated Geographic Encoding and Referencing (see TIGER).

In the late 1960s, the United States Census Bureau developed Dual Independent Map Encoding (DIME), a geographic information system to handle spatial data.
even data structures such as GBF/DIME and chaincodes have been called data models (Peuquet 1990)
While all of these definitions are clearly related and similar, they are by no means synonymous.

From the US Census Bureau anyone can obtain TIGER FILES(Topologically Integrated Geographic Encoding and Referencing). TIGER FILES combined DIME and DLG databases into a seamless map of the US, both urban and rural areas.
Census maps in TIGER format succeed the previous DIME format. TIGER files are available for every county in the United States and for the millions of census blocks in urban areas.
