vector digital data
This digital map database represents the general distribution of surficial and bedrock geologic units mapped in the Commonwealth of Virginia and compiled at a nominal scale of 1:250,000. New and modified geologic contacts were digitized on screen by geologists at approximately 1:24,000 from maps that ranged from 1:24,000 to 1:250,000-scale. The database delineates map units that are identified by general age and lithology, generally following the stratigraphic nomenclature of the U.S. Geological Survey (USGS). This metadata report provides an overview of the data content of this GeMS geodatabase and associated files.
This digital map database represents an update to the contact lines, geologic map units, and map unit descriptions found on the 1993 Geologic Map of Virginia and is intended to show the generalized geology of the state. The database also provides surficial geologic units derived from 10-meter LIDAR and new geologic mapping (where available) as a separate feature class. It is recommended that users not use the data beyond the recommended scale range of 1:100,000. Users requiring more detailed geologic mapping should refer to the original geologic map citation found the "DataSources" field of the various feature classes and non-spatial tables.

The accuracy of the geologic data varies depending on the compiled map. In general, contact lines were digitized on screen at 1:24,000-scale. The accuracy of the line work (and generated map unit polygons) is reflected in the LocationConfidenceMeters field in the ContactsAndFaults feature class. Surficial units were interpreted primarily using 10-meter LIDAR or from geologic maps, if available. All line work (bedrock and surficial) was given a corresponding data source citation, identifying the original map source for the line work or the geologist who made the contact line interpretation.
Database topology, geometric, and logical errors were identified and fixed iteratively using the "Check Topology" tool and the "Validate Database" tool in the ArcGIS GeMS Database Toolbox (available at https://github.com/usgs/gems-tools-arcmap).
The geologic bedrock data and geologic descriptions include information from published geologic maps up to 2021 and is considered to be an update to the geologic map line work originally compiled in 1993. Surficial data was digitized from 10-meter LIDAR flown between 2010 and 2019. Only surficial features that were large enough to identify at 1:24,000-scale were added to MapUnitOverlayPolys.
A personal geodatabase of the 1993 map (including contacts and map unit polygons) was imported to a GeMS format geodatabase. Original geologic map descriptions from the 1993 Expanded Explanation were copied from a Word document into the DescriptionOfMapUnits table. Citations were added from the Expanded Explanation into the DataSources table. This data was then loaded onto an ArcSDE server so that multiple editors could update and edit geologic contacts.
2019-01-01
Geologic contact lines were used to build geologic map unit polygons using the ArcGIS Feature to Polygon tool. A temporary annotation feature class was used to label the map unit polygons and symbolize (color) them.
2021-01-01
Geologic contacts where compiled and updated by geologists from various map sources. Geologists digitized contacts at a nominal scale of 1:24,000. Edge match issues were resolved by the individual geologist. Citations for the source for individual contact lines were added to the DataSources table. Surficial units were also digitized and added to the MapUnitOverlayPolys feature class.
2021-01-01
The GeMS ArcToolbox was used to validate the database, update metadata, and automate field completion.
2021-01-01
Map unit descriptions were updated for each geologic unit using the best available geologic data in an Excel spreadsheet. Citations are provided in the DataSources table and fields. Colors were chosen for each map unit. These colors were then used to symbolize the map units built in Step 3.
