The GBF/DIME Case Study

The GIS History Project

The GBF/DIME Case Study

GBF/DIME stands for "Geographic Base File" using "Dual Independent Map Encoding". The DIME system was developed at the US Bureau of the Census in 1967, in preparation for the automation of geocoding of the 1970 census. DIME was a key tecnical development in the history of GIS, but the project also is very closely connected to the birth of many key organizations in the geodemographics industry. Thus it makes an excellent high-priority case study for the history of GIS.

The GIS History Project has conducted some work on this case study, a a brief progress report on the DIME Case study has been written.
