Unioned layer of coal resource calculation in the southern Piceance Basin, Colorado (ps*fing)

공공데이터포털

These are shapefiles and coverages of final unioned polygon coverages used to calculate coal resources of the Cameo/Fairfield coal group east of 107 deg 15' longitude, and the Cameo/Wheeler, South Canyon, and Coal Ridge coal zones west of 107 deg 15' longitude in the southern Piceance Basin, northwestern Colorado. Pscbfing was used for the area east of 107 deg 15' longitude; pscwfing was used for the Cameo/Wheeler coal zone; psscfing was used for the South Canyon coal zone; pscrfing was used for the Coal Ridge coal zone. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, reliability, and, overburden. The final unioned coverage for each coal zone, was clipped by the resource boundary polygon of each coal zone.

Unioned layer of coal resource calculation in the Danforth Hills coal field, Colorado (dan*fing)

공공데이터포털

Final unioned polygon coverages and shapefiles used to calculate coal resources of the A through G coal zones, Danforth Hills coal field, northwestern Colorado. Danafing was used for the A coal zone; Danbfing was used for the B coal zone; etc. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, lease boundaries, overburden, and coal thickness categories. The final coverages were clipped to the resource areas for each coal zone, which are described in the metadata files for the *_bnd coverages.

Unioned layers of coal resource calculation in the Kaiparowits Plateau study area, southern Utah (kai*fing)

공공데이터포털

These are shapefiles and polygon coverages that contain numerous attributes of information on coal in the Calico and A-sequences of the Upper Cretaceous Straight Cliffs Formation in the Kaiparowits Plateau study area in southern Utah. These layers were derived from a "union" process of combining numerous polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick. The outside polygon defines the base of the coal-bearing Calico and A-sequences east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and basal outcrops of volcanic rocks of Tertiary age.

Coal fields and outlines of coal-bearing strata in the Colorado Plateau coal assessment study area (cpcf*g)

공공데이터포털

These are shapefiles and ARC/INFO coverages of coal fields and coal-bearing formations in the Colorado Plateau. These GIS layers were created by combining numerous ARC/INFO coverages created for the Colorado Plateau coal assessment. The coal field outlines are approximate boundaries based on criteria provided below under Data Quality Information, Process Steps. These coal field outlines may not overlap exactly with other published coal field boundaries or with criteria used in the geochemistry data. We used existing polygons taken from numerous digital geologic maps, as described in Process Steps, but did not use overburden cutoffs.
