      Abstract:
        This dataset is an polygon coverage of the Pittsburgh Coal bed and Horizon.  
        The polygons are subdivided into areas where resources are unknown, areas 
        where resources are known but not yet mined, and areas where resources are 
        known and are mined.
          Map Introduction:
        This map is one of many Geographic Information System (GIS) products of the 
        National Coal Assessment that is being conducted by the U.S. Geological Survey 
        in cooperation with State gological surveys and other Federal and State 
        agencies.  The base of the Pittsburgh Coal bed and its equivalent horizon is 
        used to subdivide Upper Pennsylvanian Series strata into the overlying 
        Monongahela Group and the underlying Conemaugh Group in the Appalachian Basin.
        This map depicts the Pittsburgh Coal bed and stratigraphically-equivalent
        non-coal strata, herein referred to as the Pittsburgh Coal bed and horizon.  
        The Pittsburgh Coal bed and horizon occurs in eastern Ohio, central and northern
        West Virginia, western Pennsylvania, and western Maryland.  This map, consisting
        of the original-extent GIS layer and the mined-area layer, will be combined with
        coal isopach and coal bed structure layers for calculating remaining coal 
        resources. On this map, four types of information are shown:  (1) original 
        extent of the Pittsburgh Coal bed and its laterally equivalent horizon; (2) 
        known mined areas of the Pittsburgh Coal bed; (3) areas of inadequate subsurface
        control, areas of impure coal, and areas where the Pittsburgh Coal bed is 
        absent; and (4) areas where mining has occurred and/or known resources exist.  
          Methods:
        The areal extent of the Pittsburgh Coal bed and horizon was digitized from 
        multiple sources using Arc-info.  The digital maps were edited manually in 
        Arcedit and appended to create a single GIS data set (coverage) for each state: 
        all were combined to create a single GIS coverage for the areal extent of the 
        Pittsburgh Coal bed and horizon.  In West Virginia, the areal extent of the bed 
        and horizon was digitized from maps in county and other reports that show coal 
        extents or outcrops for multiple beds at scales of 1:62,500 and 1:24,000 (see 
        references).  Because the county geologic maps of Gilmer and Kanawha Counties, 
        WV show miscorrelations of the Pittsburgh Coal bed (B.M. Blake, West Virginia 
        Geological and Economic Survey, oral commun., 1996) the contact between the 
        Monongahela and Conemaugh Groups (Cardwell and others, 1968) was used for the 
        areal extent of the Pittsburgh Coal bed and horizon.  The coverage for areas of 
        inadequate subsurface control, impure and absent Pittsburgh Coal and areas where
        mining has occurred and/or resources are known were obtained from three types of
        sources.  In Wetzel, Doddridge, Gilmer, and the northwestern part of Kanawha 
        Counties, lines labeled "Approximate edge where the Pittsburgh Coal bed of 
        commercial thickness and purity disappears" (Hennen, 1912) were digitized from 
        the West Virginia county report maps.  In Putnam and western Braxton Counties 
        the lines were digitized from Lotz (1970). Modifications of the published lines
        in the county reports and Lotz (1970) were made on the basis of geologic field 
        work (C.B.Cecil, U.S. Geological Survey, oral commum., 1997; Nick Fedorko, West
        Virginia Geological and Economic Survey, oral commun., 1997) in Roane, Calhoun,
        Clay, eastern Kanawha, western Braxton, southern Lewis, and western Upshur 
        Counties. In Ohio, available 1:62,500 scale maps were mosaiced into resource 
        areas by the Ohio Division of Geological Survey (ODGS) and digitized.  In 
        southern Ohio (Resource Area 13), where coal resource maps were not available, 
        the Monongahela/Conemaugh Group contact, as shown on the Geologic Map of Ohio 
        (Bownocker, 1920), was used for the areal extent of the Pittsburgh Coal bed and 
        horizon.  Areas of inadequate subsurface control, impure, or absent coal and 
        areas where mining has occurred and/or resources are known were digitized from 
        the <14 in. isopach line delineated on isopach maps of the Pittsburgh Coal bed 
        (Bronsdon, 1975). Because different criteria were used to delineate the lines 
        of known resources from areas of inadequate subsurface control, impure or 
        absent coal in Ohio and West Virginia, an offset is observed at the state 
        boundaries. In Pennsylvania, county reports, which included reduced 1:24,000
        scale maps, were digitized (see data sources).  In Maryland, the cropline of
        the Pittsburgh Coal bed was taken from the Monongahela/Conemaugh contact on the
        Geologic Map of Maryland (Cleaves and others, 1968) and revised with Berryhill
        and others (1956) in Alleghany County and an unpublished 1:100,000 compilation
        map that includes Garrett County (D. Brezinski, Maryland Department of Natural 
        Resources, Maryland Geological Survey,1997). The cropline of the Pittsburgh Coal
        bed was then built for polygon topology. Each polygon was labeled as either coal
        bearing or devoid of coal.
        The mined data were acquired from various sources.  The primary source in the 
        northern part of the Pittsburgh Coal bed and horizon was a proprietary Computer 
        Aided Design (CAD) file from the John T. Boyd Company, Pittsburgh, Pennsylvania,
        which provided data for Ohio,  much of Pennsylvania, and northern West Virginia.
        Mined areas that were not included in the John T. Boyd Company map in Greene, 
        Westmoreland, Fayette, and Allegheny Counties, Pennsylvania, were obtained from
        the Pennsylvania Topographic and Geologic Survey county reports (various dates).
        West Virginia Geological and Economic Survey Open-file mine maps (various dates)
        were used for the mined area coverage south of Monongalia and Marion Counties. 
        In Maryland, the Pittsburgh Coal bed is assumed to be mined-out at the scale 
        represented by this map (D.Brezinski, Maryland Department of Natural Resources,
        Maryland  Geological Survey, oral commun., 1996).  The John T. Boyd map (1995) 
        was geo-referenced using state boundaries and reference points with Arcedit, 
        appended with digitized West Virginia data, and both data sets were cleaned 
        manually.  The three sets of data were combined to create a single coverage and
        built for polygon topology.  The resulting coverage, a combination of the mined
        and areal extent coverages, was built for polygon topology. This final coverage
        was used to produce this map.
      Purpose:
        This dataset was produced to be used in the National Coal Assessment Program. 
        It will be utilized for resource calculations, hardcopy map products, as well
        as in an 'On-Line Energy Decision Support System' currently under construction.

  Data_Quality_Information:
    Logical_Consistency_Report:
      Topology for this data set was built using the CLEAN command within
      ARC/INFO.  This command eliminates dangling nodes, calculates inter-
      sections of arcs, eliminates redundant arcs, and creates an polygon
      attribute table.
    Completeness_Report:
      This data set is a representation of the Pittsburgh coal seam.  Although
      the source maps differentiated underground mines from surface mines, no 
      effort was made to keep them seperate in the data collection phase.  Source
      data was selected by project manager (Jingle Ruppert).  These maps are
      believed to contain the most up to date information available concerning
      the Pittsburgh coal bed.

      Process_Step:
        Process_Description:
          All paper maps were manually digitized on a tablet using ARC/INFO.  
          All digital data was converted to ARC/INFO coverages.  All data was
          then appended into one data set.  This data set was edited to 
          resolve inconsistenceies between maps and to form a polygon coverage.  
          The final data set was then attributed using the codes described 
          within this document
