Land status and Federal mineral ownership, southern Piceance basin (psowng)

공공데이터포털

This is a shapefile and coverage of ownership in the southern Piceance Basin coal assessment area, northwestern Colorado. Polygons that make up the coverage include counties, 7.5' quadrangles, townships, and surface and coal ownership. The ownership coverage was clipped by the resource boundary polygon for the coal-bearing Mesaverde Formation and Mesaverde Group which is described in the metadata file for the psmv_bnd coverage.

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.

Land status in the Colorado Plateau coal assessment study area - Colorado, Utah, New Mexico and Arizona (cplowng)

공공데이터포털

This data set portrays the land ownership polygon features in the U.S. Geological Survey (USGS) Colorado Plateau coal assessment study area (Colorado, Utah, New Mexico and Arizona). The data set was created by clipping a national land ownership coverage of federal land polygon features that had been extracted from the individual USGS 1:2,000,000-scale state boundary Digital Line Graph (DLG) files and then paneled into a single coverage. The original national coverage metadata document is included here and modified slightly to indicate that the geographic areal extent is that of portions of Colorado, Utah, New Mexico and Arizona.

Danforth Hills land and mineral ownership, Colorado Plateau (danowng)

공공데이터포털

Land status and Federal mineral ownership in the Danforth Hills coal field, northwestern Colorado. Polygons that make up the ownership coverage include counties, 7.5' quadrangles, townships, surface and coal ownership. The ownership coverage was clipped to the base of the A and B coal zones or top of the Trout Creek Sandstone Mbr.

Yampa coal field land status and Federal mineral ownership (yamowng)

공공데이터포털

This is a shapefile and unioned polygon ownership coverage used to calculate coal resources of the A through D coal zones, Yampa coal field, northwestern Colorado. Polygons that have been combined include counties, 7.5' quadrangles, townships, surface and coal ownership. This ownership coverage was clipped by the largest resource boundary polygon--that of the A coal zone.

Land status and Federal mineral ownership in and around the Powder River Basin, WY and MT (prbplusown98g)

공공데이터포털

This is a coverage of surface and Federal mineral ownership in the Powder River Basin area, Montana and Wyoming. This coverage is the combination of several ARC/INFO coverages and MOSS format files that were collected from the BLM, reformatted as needed, modified, and/or created by the USGS from hard copy BLM 1:100,000-scale surface and mineral management status maps. The Powder River Basin has the largest in-place coal resources of any field in the contiguous U.S. (Keystone, 1997), and produces over one-fourth of the Nation's total coal production (The Mining Record, 1997). In the Powder River Basin, very little of the surface is Federal land, yet almost all of the coal is Federally owned.

Area of coal-bearing Mesaverde Formation and Mesaverde Group, southern Piceance Basin assessment area, Colorado (psmvbndg)

공공데이터포털

This is a shape file and coverage of the top of the Rollins Sandstone Member. It outlines the area underlain by the coal-bearing Cameo/Fairfield coal group in the southern Piceance Basin coal assessment area. Also, it delimits the area within which resources were calculated and reported in the southern Piceance Basin coal assessment area. The polygon was adjusted to match the topography of the DEM.
