Abstract:
This dataset is an polygon coverage of the Pittsburgh Coal bed and
Horizon. The polygons are subdivided into areas where Pittsbugh Coal
originally existed and areas where Pittsburgh Coal did not originally
exist. This data set is intented to be used in conjunction with C9024MO
(Mined Areas, Pittsburgh Coal), C9024ST (Pittsburgh Coal Structure
Contours), C9024IS(Pittsburgh Coal Isopach Contours), C9024OB (Pittsburgh
Coal Overburden Contours), C9024RC (Pittsburgh Coal Reliability Circles),
and C9024FIN (Union of the above coverages and county boundaries).
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.
This metadata file deals exclusively with the 'Outcrop' coverage of the
Pittsburgh coal bed. The dataset is officially known as C9024OC.
Methods:
The areal extent of the Pittsburgh Coal bed and horizon was digitized from
multiple sources using Arc-info and Arcedit. 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.
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.

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 bed mined areas. Source of
data was selected by project manager (Jingle Ruppert). These maps
contain the most up to date mining information available concerning the
Pittsburgh coal bed.

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 inconsistencies between maps and to form a polygon coverage.
The final data set was then attributed using the codes described
