Description Abstract The geologic data was reproduced and updated from a previously published paper map at 1:24,000 scale: Geology of the Cainhoy, Fort Moultrie, Charleston and North Charelston Quadrangles, Charleston and Berkeley Counties, South Carolina, by Robert Weems and Earl M. Lemon, 1993, USGS Miscellaneous Investigation Series, Map I-1935. The original published map was constructed using data from numerous auger holes drilled throughout the quadrangle. The data from these auger hole samples was used to identify the number and types of units and their distribution throughout the quadrangle. The sedimentary units represented here have geomorphic expressions in the Charleston area and those expressions were used to aid in construction of the geologic map data. Through the interpretation of aerial photographs and the Charleston County soils maps these geomorphic expressions were identified and the geologic units mapped accordingly. Additional field investigations were conducted by staff geologists to assure accuracy of mapped data. The geologic data was scanned from a map separate provided on film at 600 dpi using an Anatech Eagle 4080ET scanner. The raster layers were then vectorized in GTX OSR raster-to-vector conversion software. The resultant DXF files were imported into Arc/Info GIS software (versions 7.0.4 and 7.1.1), transformed and then registered to the basemap coverages of hydrography and transportation Digital geology was overlaid and corrected relative to the 1:24000 hydrography and hypsography boss layers. Purpose The 1993 paper map was published as a part of a USGS study of the seismicity of the greater Charleston, SC area. The seismicity study was funded, in large part, by the U.S. Nuclear Regulatory Commission. The digital reissue is intended for use by all government, academic, and commercial agencies in need of digital geologic map information. Supplemental_Information Procedures_Used Revisions Reviews_Applied_to_Data The geology dataset was printed and visually reviewed by the map authors and other geologic staff of the Eastern Region Geologic Mapping Team for geologic integrity, completeness and linework accuracy. The attribute codes of the polygon attribute table for the geology coverage were checked for valid codes and found to be suitable. Related_Spatial_and_Tabular_Data_Sets char_geol.lt : The relate item is TYPE and corresponds to the geologic units represented by the polygon coverage. This tablular data set accompanies the geo data set and provides a symbol code for each geologic unit polygon. The item for symbol number reference is called SYMBOL and the valid codes are numeric between 1 and 500. These numbers correspond to colors in c500.shd, the shadeset used to plot the hardcopy maps on a 44 inch Versetec plotter.
