The Karst Occurrence GIS polygon coverages for Kentucky were compiled from a digital version of the 1:500:000-scale geologic map of Kentucky (Noger, M.C., 1988). Because of the 1:500,000 scale of the source map,

these coverages should NOT be used for evaluating karst geologic hazards or hydrogeology at scales larger than 1:500,000. The classification of the potential for karst development was based on the field experience of the authors and other data. A number of isolated carbonate units were newly digitized for these coverages.
