Description
This dataset includes geologic stuctural contours of varying datums across Kentucky in shapefile format. These structural contours are compiled from structural contour layers published as a part of the individual Digitally Vectorized Geologic Quadrangles (DVGQ) datasets (by the Kentucky Geologic Survey: https://kgs.uky.edu/kygeode/services/pubs/?pubtype=DVGQ&searchtype=pubcategory). The original structural contours were mapped on the 7.5-minute (1:24,000 scale) series geologic maps published during the Kentucky geologic mapping program (Kentucky Geological Survey - U.S. Geological Survey from 1960 to 1989: https://kgs.uky.edu/kygeode/services/pubs/?pubtype=GQ&searchtype=pubcategory). The digital contours were subsequently digitized as a part of the DVGQ datasets during the geologic digital mapping program at KGS (1996 – 2007). Contoured formations were determined by the original quadrangle map author, therefore contour datum may vary across quadrangle boundaries. These structural contours are not based on subsequently obtained subsurface data and should only be used as a general guideline for the underlying geologic structure. Contours are in feet above sea level, and may vary in contour interval across quadrangle boundaries. Please note that some contours are projected above the land surface. Refer to the metadata and supporting information for detail about the data fields and data attributes.
