This ArcView shapefile contains a polygon representation
of surface and subsurface ownership in the Powder
River Basin. This theme was created specifically for the
National Coal Resources Assessment in the Northern
Rocky Mountains and Great Plains Region.
Purpose:
The Nation's coal resources are being assessed by the
USGS. This assessment identifies and characterizes
the coal beds and coal zones that will provide the
bulk of the Nation's coal-derived energy during the
next few decades. This assessment is different from
previous USGS assessments because digital files
and databases are being collected and stored in
standardized formats, and being analyzed using a
Geographic Information System (GIS).

Access_Constraints: None
Use_Constraints:
The surface and mineral management status are published
as general planning and management tools. The official
land records in the respective offices of the Bureau of
Land Management or other Federal agencies should be
checked for up-to-date status on any specific tract of land.

Margaret Ellis, U.S. Geological Survey, created the
coverage for the outline of the Powder River Basin based
on geologic studies. The basin outline represents the base
of the Tertiary Fort Union Formation, or the general
Cretaceous-Tertiary boundary. The northeastern portion of
the boundary was generalized along the Miles City Arch
area and the Yellowstone River.

Federal land and mineral ownership in the Douglas
quadrangle, Wyoming.
Process_Step:
Process_Description:
100,000 hardcopy BLM maps were used for reference.
The items
SURF (surface ownership) and FEDMINS (Federal mineral
ownership) were added to the Polygon Attribute Table
(PAT) and both defined as 8-character fields. SURF was
populated using the existing item, STATUS, or by visual
100,000-scale quadrangle BLM maps to identify bodies of
water. Through interaction with the MT State BLM office,
and by reference to the corresponding hard copy BLM
maps, the item FEDMINS was populated. The ARC/INFO
coverage's obtained from the MT State BLM office are
more recent 100,000-scale quadrangles; therefore, the
ARC/INFO coverage's were honored when small
discrepancies were found, especially in areas less than 1/2
section. After attributes were assigned, the coverage's
were proofed visually by creating hardcopy plots to
compare with the BLM original maps. Each quadrangle
coverage is housed in a USGS Central Energy Resources
Team Data Library. A copy of each of the completed
coverage's was provided in its original projection to the MT
State BLM office and ultimately to the Montana State
Library. All of the quadrangles that are appended for the
Powder River Basin coverage have been projected to
Lambert meters with the parameters used for this coverage.
24,000 scale, and include both the surface and mineral
ownership status as well as types of minerals reserved to
the government. The MOSS file is in State Plane meters -
zone 5801; it was imported into ARC/INFO using the
MOSSARC command and projected to Lambert meters
with the parameters used for this coverage. The polygon
attribute item, DATA, contains a 6-character ownership
attribute coding scheme used by the WY State BLM office,
and referred to as the "pizza" code. Letter identifiers within
this code define surface ownership, subsurface ownership,
agency with jurisdiction, and mineral reservation. The 6th
character of the "pizza" code (withdrawal type) was
incomplete, so was not used. In ARC/INFO, DISSOLVED
on item 5 of the pizza code to eliminate the incomplete 6th
character. Through interaction with the WY State BLM
office and by referencing a "pizza" code key provided by
that BLM office, the USGS populated the polygon attribute
items SURF and FEDMINS to conform to the attributing
standards that the USGS has set for our ownership
coverages.
100,000-scale quadrangles (Bill, Midwest, Douglas,
Sundance, Newcastle, Lance Creek, and Lusk). BLM
separates for the most recent BLM surface and mineral
management status maps were scanned and vectored
using AutoCad. The AutoCad polygons were attributed
and then converted to Arc/Info coverage's where they
were merged into one seamless coverage using the
Arc/Info UNION command. The completed coverage's
contain polygon attributes in items SURF and FEDMINS.
100,000-scale quadrangle coverages were processed
using ARC/INFO ERASE, APPEND, and UPDATE as
needed to create one coverage for the entire basin.
Following APPEND, this Powder River Basin coverage
was processed using CLEAN to create polygon topology
(BUILD wouldn't work because there were intersections).
The before and after CLEAN coverage's were compared
and no appreciable line offsets were found. The coverage
was edited to delete extraneous polygons created during
APPEND, and to add arcs where needed in a gap
between the Montana data and the Wyoming data at the
State line. DISSOLVE was used to eliminate quadrangle
boundaries and any other extraneous arcs and polygons.
Some minor polygons defining Federal Agency Protective
Withdrawals and Public Water Reserves were lost in the
DISSOLVE routine. In the Sheridan and Recluse
quadrangles, some minor detail on Power Withdrawals and
Classifications, and Bureau of Reclamation lands were lost.
The Powder River Basin area ownership coverage was
intersected with the Powder River Basin boundary
coverage to eliminate the data outside of the Powder River
Basin as defined for the National Coal Assessment.
We have subsequently found problems with the region
subclasses when we attempted to project this coverage. A
message alerts that an unclosed region was detected.
However, REGIONERRORS reports no unclosed region
detected for this coverage. The DROPFEATURES
command can be used to delete a region subclass from
this coverage before projecting.
