ARE WE ORGANIZED FOR BRINGING MAXIMUM MAPPING BENEFITS TO SOCIETY? A STATE GEOLOGICAL SURVEY PRACTITIONER PERSPECTIVE

The Kentucky Geological Survey has an extensive geologic mapping legacy: complete statewide bedrock maps, 15 years of STATEMAP-supported surficial mapping, a robust capability for data delivery, and development of applied derivative products. Key points for ensuring maximum benefit for geologic-map audiences have been learned. Studies show a high ROI for geologic mapping. Maximum value is only achieved when the data are trusted (high quality, accurate), readily accessible (free, available, digital), and standardized (well documented, explained). Complete coverage for the municipality is essential so that nongeologic users can anticipate using the data and will therefore integrate them into their business procedures and decision-making processes. Much of the value of geologic mapping is realized through technical derivative map products for nongeologists; many of these applications require separate consideration of bedrock and surficial materials.

Several valuable tools support state geological surveys working toward increased geologic map coverage. EDMAP produces a trained and skilled workforce. The AASG facilitates communication and collaboration among states. The USGS-AASG DMT workshops enable technology transfer among digital geologic mapping practitioners. STATEMAP provides a critical source of funding. The USGS National Geologic Map Database facilitates cataloging and distribution of geologic map products.

Unfortunately, the support for mapping is incomplete. As with many programs, STATEMAP and EDMAP are underfunded. There is no central source of funding for development of technical derivative products; diversion of the limited funds currently available for geologic field mapping into endeavors such as derivative mapping or other earth science research studies would further damage the already slow pace of map production. At the current average rate of map publication, completion of a nationwide map layer could take more than 50 years, which is completely unacceptable. There are wide disparities in the support for individual state surveys; additional mechanisms are needed to assist each other. Unstated academic perceptions of geologic mapping as only a research tool, and not a valuable stand-alone product, also continue to hamper efforts to achieve nationwide geologic mapping.
