Three hundred sixty-eight geologic map$ of 7-1/2 minute quadrangles in Tennessee were coverted to geographic information system (GIS) coverages. The procedure used was documented and a list was made of the quadrangles included in the coverages. Maps were converted to GIS coverages by making film copies of scribecoats of the maps. The film copies were scanned, vectorized, and written into a generate format. Coverage polygons were tagged with symbels to identify geologic units, and coverage lines were tagged with line types to designate stratigraphic contacts.
