      Title: Approximate Elevation of pre-Cretaceous Basement Rock Beneath Coastal Plain Deposits in Maryland
      Geospatial_Data_Presentation_Form: vector digital data
  Description:
    Abstract: Point locations with borehole data from the Coastal Plain of Maryland
    Purpose: This map represents a reorganization of select Maryland Coastal Plain borehole data into a format compatible with GeMS (Geologic Map Schema), as established by the U.S. Geological Survey National Cooperative Geologic Mapping Program. Borehole data are chiefly derived from the Maryland Geological Survey Maryland Coastal Plain Aquifer Information System (Andreasen et al., 2013), with additional lithologic data from Maryland Geological Survey Report of Investigations No. 44 (Hansen and Edwards, 1986). The complete digital geologic map and associated geodatabase are available for download at the Maryland Geological Survey home page.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Data accuracy was not evaluated as part of the compilation of this map dataset
  Logical_Consistency_Report: Topology tests were conducted to ensure the integrity of geospatial data. Original data sources were rechecked multiple times to ensure no data were omitted from this map.
  Completeness_Report: Only data from boreholes drilled in the Coastal Plain of Maryland were included in this compilation map. Boreholes drilled elsewhere in Maryland are not the subject of this map.
