The Black Hills Digital Mapping Association originated in the early 1990's because of a need for the development of digital data in the Black Hills of South Dakota. Geographic Information System base data layers were desired, and coordination and sharing of funds between local counties, the state, the US Forest Service, and the USGS enabled the creation of these digital products. The group continues to meet on an annual basis because there is a strong desire among members to learn about new technologies, learn how GIS projects are being implemented in this region, receive training, and learn about data sharing opportunities.

The organization registered with the State of South Dakota as a non-profit corporation in 2005. The membership base includes representatives from all levels of government (Federal, State, County, and City), academia, tribal, and the private sector, and includes over 100 members.
