  Description:
    Abstract:
      The bedrock feature class of the geologic map of the Mason and Dixon 7.5-minute quadrangle, Washington County, Maryland (1:24,000 scale; 1 inch = 2,000 feet).  Geologic field mapping in the quadrangle was conducted in 2010-2012 by David K. Brezinski. This map area is included in an investigation of karst development in the Hagerstown Valley.  The karst investigation was conducted by the Maryland Geological Survey as part of a collaborative effort with the Maryland State Highway Administration and the USGS STATEMAP component of the National Cooperative Geologic Mapping Program. 

      The geologic components were originally drafted onto stable-base material using the corresponding U.S. Geological Survey (USGS) topographic quadrangle map as a base (1:24,000 scale).  The digital geologic map was developed for geographic information systems (GIS) using ESRI's ArcGIS Desktop software.  The geologic map is produced in the Maryland State Plane Coordinate System (Lambert conformal conic projection, NAD83, meters) (1:24000 scale).

      The components of the digital geologic map are divided into separate feature classes for bedrock geology, surficial Quaternary deposits, structural line features (e.g., faults), structural point features (e.g., bedding measurements), and geologic cross-section elements.  Digital base map layers were derived from a USGS US Topo digital topographic map for this quadrangle and other sources (see supplemental_information).

      Digital feature attributes for the bedrock geology file include unit labels, unit names and abbreviated lithologic descriptions for the coverage polygons and certainty and general type of geologic contacts for the coverage arcs.
    Purpose: To display geologic units and formations in a GIS-based geologic map.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: The geologic map was hand drawn on stable-base film (e.g., Mylar or Herculene) at a scale of 1:24,000 by the principal geologist based on standard geologic mapping techniques, which involves the integration and interpretation of field observations and available subsurface data (e.g., drilling logs, geophysical logs). The hand-drawn map includes geologic contact lines and coded labels for the geologic map units.  Digital attributes were assigned during the creation of the geology feature class in ArcGIS Desktop.  Each polygon has a unit label attribute designating the mapped geologic unit provided by the principal geologist or MGS GIS project coordinator/editor.  Additional polygon attributes for the digital files were provided by the MGS GIS project coordinator.  Feature attributes were then verified visually in the ArcGIS attribute tables; attributes linked to map layout components were verified visually on the map both in print and symbolized display on-screen.  Maryland Geological Survey performs quality assurance on the digital vector file by comparison of the digital data files and map to the original films. Selected attributes that cannot be visually verified on plots or on screen are interactively queried and verified on screen by the GIS project coordinator and GIS specialist(s)
  Logical_Consistency_Report: Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure and other errors by the GIS project coordinator and GIS specialist(s) who created the digital data. Hard copy prints of the map were reviewed by the MGS geologists for consistency with basic geologic principles and general conformity to mapping standards.  The graphic data has been tested for consistency through the application of ArcGIS topologic testing.  Polylines were tested to a 0.001 tolerance for overlap or gaps between line features and adjacent geologic formation polygons.
  Completeness_Report: Omissions in geologic unit data would be due primarily to hidden or undiscovered surface units.  The stratigrapher has employed accepted standard procedures and due diligence to ensure the construction of reasonable geologic models. Updates may occur as needed or as additional data become available. Check MGS website for version number or contact MGS Publications Office (see Distribution_Information).  Data are complete based on compilation at 1:24,000 scale.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Horizontal accuracy of the digital vector file was tested by comparing proof plots with original mylar(s) of the map prepared by the principal geologist(s) at a scale of 1:24000. The comparison was done visually by MGS geologists and the GIS team.  Some corrections/adjustments to contact locations were made per instruction of the principal geologist, directly in the digital form.  The difference in the positional accuracy between the geologic unit contacts as drawn and digitized and the contacts in the field is difficult to quantify in geologic mapping of this type.  Where a contact between two bedrock units is concealed by a mappable thickness of overlying Quaternary materials (e.g., alluvium, colluvium, residuum, terrace deposits or artificial fill) the location is an estimate indicated by a dotted line on the map (attributed as "concealed" in the attribute table).  Where a bedrock contact is not concealed by mappable Quaternary deposits, the certainty of a contact's location may vary because many bedrock contacts are not exposed everywhere (they are often covered by soils and/or vegetation in places).  In these situations the location certainty/accuracy of geologic contacts has been designated by the principal geologist as accurate (symbolized by a solid line), approximate (a long dash pattern), or inferred (a short dash pattern).

    Process_Step:
      Process_Description: The geology was compiled onto stable-base film, using the USGS 0.007-inch-thick film positives of the 7.5-minute topographic maps as an underlying stable base.  Original scale of map is 1:24,000 (1 inch equals 2,000 feet).  Eight spatial reference points were added to the geology film for georeferencing purposes - the 4 quadrangle corners (geographic coordinates, and four tick marks internal to the base map quadrangle.
      Process_Date: Unknown
    Process_Step:
      Process_Description: Base-stable Mylar cross section artwork was scanned at 300 dpi by a commercial scanning bureau and saved to TIF format image.
      Process_Date: Unknown
    Process_Step:
      Process_Description:
        The scanned TIFF image was brought into ESRI ArcGIS Desktop software and georeferenced (or registered and rectified) to UTM18N, NAD 1983, meters.  The above-mentioned spatial reference points were used as linking points.  When rectifying, nearest neighbor interpolation at a polynomial of 3 was used and attempts were made to achieve the lowest root mean square (RMS) error possible, which for the geology layer was approximately 0.0007. (RMS error is not reported in digitizer inches or physical map inches or millimeters.)  All work--including georeferencing, digitizing and re-projection was in double precision.

        The image was then re-projected to Maryland State Plane Coordinate System 1983 (FIPS 1900), meters

      Process_Description: Geologic unit polygons on scanned image were digitized on-screen at a scale of 1:5000 or greater.  Attributes were added.
