U.S. Geological Survey
This database refers to the following publication: Weems, R.E., Lewis, W.C., and Lemon, E.M., Jr., 2014, Surficial geologic map of the Charleston region, Berkeley, Charleston, Colleton, Dorchester, and Georgetown Counties, South Carolina: U.S. Geological Survey Open-File Report 2013–1030, 1 sheet, scale 1:100,000, http://dx.doi.org/10.3133/ofr20131030
https://doi.org/10.5066/P9HB0RFE
This database portrays the surface and shallow subsurface geology of the greater Charleston, S.C. region east of 80°30′ west and south of 33°15′ north. The region covers the entirety of Charleston County and portions of Berkeley, Colleton, Dorchester, and Georgetown Counties. Units locally exposed at the surface range in age from middle Eocene to Holocene, but most of the area is covered by Quaternary interglacial deposits. These are, from oldest to youngest, the Okefenokee, Waccamaw(?), Penholoway, Ladson, Ten Mile Hill, and Wando Formations and the Silver Bluff beds. Two cross sections (not included in the database), one running southeast from Harleyville to the coastline on James Island and the other running along the coastal barrier islands from the town of Edisto Beach to the northeast end of Bull Island at the southwest edge of Bull Bay, portray the complex geometry of the Paleogene and Neogene marine units that directly lie beneath the Quaternary units. These older units include the Santee Limestone, Tupelo Bay, Parkers Ferry, Ashley, Chandler Bridge, Edisto, Parachucla, and Marks Head Formations, the Goose Creek Limestone, and the Raysor Formation. The estimated locations of deeply buried active basement faults are shown which are responsible for ongoing modern seismicity in the Charleston, S.C. area.
The database for the Surficial Geologic Map of the Charleston Region, Berkeley, Charleston, Colleton, Dorchester, and Georgetown Counties, South Carolina is intended to serve as a foundation for applying geologic information to problems involving land use decisions, groundwater availability and quality, earth resources such as natural aggregate for construction, assessment of natural hazards (earthquakes), and engineering and environmental studies for waste disposal sites and construction projects.
CharlestonSCOFR2013-1030.gdb is a composite geodataset that conforms to "GeMS (Geologic Map Schema)--a standard format for the digital publication of geologic maps", available at http://ngmdb.usgs.gov/Info/standards/GeMS/. Metadata records associated with each element within the geodataset contain more detailed descriptions of their purposes, constituent entities, and attributes. An OPEN shapefile versions of the dataset is also available. It consists of shapefiles, DBF files, and delimited text files and retains all information in the native geodatabase, but some programming will likely be necessary to assemble these components into usable formats. These metadata were prepared with the aid of script GeMS_FGDC1_Arc10.py, version of 2 February 2022.

Confidence that a feature exists and confidence that a feature is correctly identified are described in per-feature attributes ExistenceConfidence and IdentityConfidence where known. Geologic information was garnered from 1:24,000-scale mapping of geologic material based on observation from fieldwork, previously published geologic maps, and unpublished geologic data in the region. The geologic information might change if additional outcrops are discovered or exposed as the natural land changes, or as the result of development, or advances in scientific research are made. The features in the database are not based on legal parcels or definitions. This database validates to level 2. Level 3 validation required the removal of data sources not attributed directly within the database. Those data sources will not be removed as they are used in the references cited on the published geologic map.
Geologic information was garnered from 1:24,000-scale mapping of bedrock material based on observations from and geologic fieldwork in the region. The geologic information might change if additional outcrops are discovered or exposed as the natural land changes or as the result of development. The features in the database are not based on legal parcels or definitions. Topology tests were performed to ensure the integrity of the data. These tests checked for polygon overlaps and gaps and line pseudos, dangles, overlaps, and intersections. Additional tests were conducted to ensure that linework from geologic contacts match polygon boundaries where necessary. There should be no duplicates in the data set where it is not intended.
Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Estimated accuracy of horizontal location is given on a per-feature basis by attribute LocationConfidenceMeters. Values are expected to be correct within a factor of 2. A LocationConfidenceMeters value of -9 or -9999 indicates that no value has been assigned. Values are expected to be correct within a factor of 2. Data were delineated on classic U.S. Geological Survey (USGS) 7.5-minute topographic maps at 1:24,000 scale. Therefore, the horizontal accuracy is assumed to be within National Map Accuracy Standards, with a horizontal accuracy of 45.6 feet at the 95% confidence level. In addition, the horizontal accuracy standard requires that the positions of 90 percent of all points tested must be accurate within 1/50th of an inch (0.05 centimeters) on the map. For more information see U.S. Geological Survey Fact Sheet 171-99.
The data were delineated on classic U.S. Geological Survey (USGS) 7.5-minute topographic maps at 1:24,000 scale. Therefore, the vertical accuracy is assumed to be within National Map Accuracy Standards, with a vertical accuracy of 11.9 feet at the 95% confidence level. In addition, the vertical accuracy standard requires that the elevation of 90 percent of all points tested much be correct within half of the contour interval. For more information see U.S. Geological Survey Fact Sheet 171-99.

This citation was used in the production of this database, either in the description of map units, or the production of geologic polygons, contacts and faults, or the additional supporting structural and cartographic information.
This database was constructed directly from the 1:100,000-scale map by exporting from Adobe Illustrator only bedrock contacts, water, and the neat line as a .tiff. The tiff was registered and rectified in NAD 83, zone 17N in ArcGIS 10.8. In ArcGIS the tiff was classified to remove water boundaries, keeping only geologic contacts. ArcScan was then used to autovectorize the bedrock lines in the ContactsandFaults feature class. The original water contacts used for the original publication were added into that feature class as well. Additional updates to linework were completed at this time, any changes in the original published geologic map were noted in the "Notes" field of the ContactsandFaults feature class. The ContactsandFaults feature class was checked topologically to remove dangles and pseudos in preparation for the creation of MapUnitPolys. Using the FeaturetoPolygon tool in ArcGIS, the ContactsandFaults feature class was converted into a shapefile and loaded into the MapUnitPolys feature class. It was attributed using an older polygon point shapefile obtained from a previous iteration of the map. Following this, an older shapefile containing smaller water bodies was imported into the OverlayPolys feature class. At this time, it was decided that the ContactsandFaults would not contain concealed contacts as the water bodies provided and shown on the original published geologic map were not derived from modern lidar, nor were those contacts shown on the published geologic map. IsoValueLines were loaded into the database from an existing shapefile that was used for the published geologic map. This feature class is available for viewing in the published geologic map as a "hidden" layer. The GenericPoints feature class was populated from an existing shapefile. This original shapefile was derived from the registration of existing published 24,000-scale maps and auger data containing locational information. The CartographicLines feature class was populated using two existing shapefiles. One for the cross section lines and another containing the neat lines (map boundaries) for the 24,000-scale maps used to construct the published geologic map. These neat lines were used to "cut" the ContactsandFaults feature class so that the lines could be properly sourced with information contained in the DataSourcePolys feature class. In this way, all linework is associated directly to those publications where necessary. Contacts within the ContactsandFaults feature class were also split at existing faults, though none of these faults cut through any geologic material shown (there should be no offset in units). The CorrelationofMapUnits feature dataset was created directly from the published geologic map by exporting the correlation from the published geologic map to CAD (.dxf) format. The CAD file was then converted to a shapefile and spatially adjusted to fit the location on the published geologic map. Once this was complete the polygons were created and attributed and the CMUText was created to match the published geologic map. The Glossary, DescriptionofMapUnits, and DataSources tables were copied directly from the published geologic map.
