Dual Independent Map Encoding
Encyclopedia
Dual Independent Map Encoding (DIME) is an encoding
scheme developed by the US Bureau of the Census
for efficiently storing geographical
data. The committee behind the case study that eventually resulted in DIME was established in 1965, although the term DIME itself was first coined by George Farnsworth in August of 1967. The file format
developed for storing the DIME-encoded data was known as Geographic Base Files (GBF). The Census Bureau replaced the data format with Topologically Integrated Geographic Encoding and Referencing
(TIGER) in 1990.
