Historically, geologic maps have perhaps been the most popular publications sold by geological surveys. Demand has been greatest among geologists, engineers, and consultants. Others, however, have been unaware of the potential uses of geologic maps. Therefore, their full value has not been captured. Geographic information systems (GIS) and digital geologic map data have recently enabled land-use planners, agricultural producers, emergency-response personnel, and others to use geologic map data. Use by this nontraditional customer base remains limited, however. It is challenging to explain to persons who are not geologists how these data can be used to address earth-science and land-use issues. The Kentucky Geological Survey (KGS) adopted a communication strategy to expand its customer base. A citizen’s guide was published with colorful illustrations and photos that complement a simple, easy-to-understand explanation of geologic maps. It gives examples of the use of geologic map data to address common problems such as landslides, floods, sinkholes, subsidence, and pollution of groundwater. New derivative map products explain local and county land-use planning and geology, the intensity of karst occurrence, and underground flow paths for groundwater in karst terrane. Presentations have been made to explain geologic maps and their use to land-use planners, agricultural producers, and others. Map data and interactive maps are also being made available on the KGS Web site.
