Digital Mapping Association
Advancing the Geospatial Profession
Jerry Penry, Professional Surveyor, Author/Lector
When maps of the United States became more spatially correct in the mid 1800’s, an endeavor was begun to identify the geographical center of the nation. What started as curiosity, later evolved to a perceived importance for tourism or potential industry. Several areas in Kansas sought the title when different government agencies identified separate locations. South Dakota entered the picture in the 1950’s when the states of Alaska and Hawaii were added which created a significant shift for the center. The geographical center of the North American continent was a similar, but separate issue, when Pierre, SD, initially claimed the location, but was later claimed by Rugby, ND. This presentation will show how South Dakota has been directly involved in determining both geographical centers.
Thank you to the 2018 conference sponsors and trainers!
Without you, our conference would not be as successful.
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.
