Land and mineral ownership coverage for the Uinta Basin, Wasatch Plateau and surrounding areas, northeastern Utah

This Arc/Info coverage contains land status and Federal and State mineral ownership for approximately 25,900 square miles in northeastern Utah. The polygon coverage (which is also provided here as a shapefile) contains three attributes of ownership information for each polygon. One attribute indicates whether the surface is State owned, privately owned, consists of Tribal and Indian lands, or, if Federally owned, which Federal agency manages the land surface. Another attribute indicates where the Utah School and Institutional Trust Lands Administration (SITLA) maintains full or partial subsurface mineral rights. The third attribute indicates which energy minerals, if any, are owned by the Federal govenment. This coverage is based on land status and Federal and State mineral ownership data compiled by the U.S. Geological Survey (USGS), the former U.S. Bureau of Mines (USBM), and the Utah School and Institutional Trust Lands Administration at a scale of  1:100,000.  This coverage was compiled primarily to serve the USGS National Oil and Gas Resource Assessment Project in the Uinta-Piceance Basin Province and the USGS National Coal Resource Assessment Project in the Colorado Plateau.

Abstract:
This Arc/Info coverage contains land status and Federal and State mineral ownership for approximately 25,900 square miles in northeastern Utah. The polygon coverage (which is also provided here as a shapefile) contains three attributes of ownership information for each polygon. One attribute indicates whether the surface is State owned, privately owned, consists of Tribal and Indian lands, or, if Federally owned, which Federal agency manages the land surface. Another attribute indicates where the Utah School and Institutional Trust Lands Administration (SITLA) maintains full or partial subsurface mineral rights. The third attribute indicates which energy minerals, if any, are owned by the Federal govenment. This coverage is based on land management status and Federal and State mineral ownership data compiled by the U.S. Geological Survey (USGS), the former U.S. Bureau of Mines (USBM), and the Utah School and Institutional Trust Lands Administration at a scale of 1:100,000.  This coverage was compiled primarily to serve the USGS National Oil and Gas Resource Assessment Project in the Uinta-Piceance Basin Province and the USGS National Coal Resource Assessment Project in the Colorado Plateau.
Purpose:
As United States energy resources continue to be examined for potential development, there is sustained interest in Federally owned energy resources in the western United States. The U.S. Geological Survey's GIS data sets of surface and Federal mineral ownership, joined with USGS geologic investigations, provides information on where Federally owned energy resources are located and how much Federal petroleum and coal exists. These ownership and resource data are the basis for answering complex geospatial queries when the data are combined with quality, structure and other parameters generated from geologic investigations. Combining information on land status, Federal mineral ownership, and geology helps policy makers and land-use planners make informed decisions regarding use of Federal land and energy resources to meet diverse social needs.

 
Surface ownership can differ from energy and other mineral ownership for the same piece of land. For example, the oil and gas may be Federally owned, but the surface may be under the jurisdiction or management of State, Tribal, or private groups. This separation of jurisdiction may have legal ramifications in the development or non-development of energy resources.

 
The U. S. Geological Survey (USGS), in cooperation with the Bureau of Land Management (BLM) and State agencies, is collecting ownership files and compiling them in Arc/Info coverages. The coverages contain a USGS standardized attributing scheme and are stored in a data library where they are accessed and combined with models of oil, gas and coal geology to assess National energy resources (see information from the U.S. Geological Survey available on 10/5/99 on the World Wide Web at <URL:http://energy.cr.usgs.gov/fedland/FS12-98/> and at <URL:http://greenwood.cr.usgs.gov/pub/fact-sheets/fs-0145-99/>). Similar data are being created in northwestern Colorado (in press) primarily to serve the U.S. Geological Survey National Oil and Gas Resource Assessment Project in the Uinta-Piceance Basin (province 20) and in southern Wyoming (in press) for portions of provinces 36, 37 and 39.

 
Federally owned energy resources play an important role in supplying energy to our Nation. Oil production from Public Lands in Utah was over 4.6 million barrels in 1998; natural gas production was over 62 billion cu. ft. Coal production from Public Lands in Utah was over 22 million short tons in 1998 (available 10/12/99 on the World Wide Web at <URL:http://www.ut.blm.gov/ff64.html>).
Federally owned energy resources also play an important part in the economy of our Nation. The combined production value of the above commodities from Public Lands in Utah was over $675 million; Federal revenues were over $54 million (available on 10/12/99 on the World Wide Web at <URL:http://www.ut.blm.gov/ff61.html>).

Data_Set_Credit:
Roberts, C.A., U.S. Forest Service, provided INFO files defining Federal mineral ownership based on work done by the former U.S. Bureau of Mines (USBM) for "Availability of Federally Owned Minerals for Exploration and Development in Western States, Utah, 1988."

 
Roe, J., Utah School and Institutional Trust Lands Administration, provided the Utah statewide digital Public Land Survey System (PLSS) in 1995. This PLSS is the same one that was available 7/8/99 on the World Wide Web at <URL:ftp://168.178.199.148/pub/index.htm>.

 
Colley, R., USGS student hire, worked on an earlier version of this ownership coverage. That version was subsequently superceded following the 1998 Utah State/Federal Land Exchange.

Attribute_Accuracy_Report:
The Arc/Info coverage of land status was obtained on 7/8/99 from the Utah School and Institutional Trust Lands Administration (SITLA) as an Arc/Info EXPORT file (aolsa.e00). The file had been updated in 7/99 and was available on the World Wide Web at <URL:ftp://168.178.199.148/pub/index.htm>. The data were at a scale of 1:100,000. This coverage also contained information on State mineral ownership that was used to populate the item (field) STATEMINS, and was used to show where the Utah Trust Lands maintain full subsurface mineral rights (ALL) and where the Trust Lands retain partial subsurface mineral rights (SOME). This coverage reflects the Utah land and mineral exhanges that took place following the "Utah Schools and Lands Exchange Act of 1998" (Public Law 105-335,105th Congress).

 
The coverage of mineral ownership was created using an INFO file that contains items (fields) that categorize oil, gas, coal and other minerals ownership based on the work done by the former U.S. Bureau of Mines (USBM) for their publication entitles, Availability of Federally Owned Minerals for Exploration and Development in Western States, Utah, 1988. The method used by the USBM to generate subsurface mineral management status was to generalize to the section level. Each whole section is defined as being the management status of 50 percent or more of that section. This INFO file was joined to a portion of the statewide Public Land Survey System (PLSS) on a common item that defined section, township, range and quadrant. The land and mineral ownership coverages were combined in Arc/Info using the UNION command. Attributes were added and populated in accordance with the standard attributing scheme developed by the USGS for land status and minerals owned by the Federal Government (see information from the U.S. Geological Survey available on 10/5/99 on the World Wide Web at <URL:http://energy.cr.usgs.gov/fedland/FS12-98/part4.html>). Federal mineral ownership was updated based on State mineral ownership information found in the coverage from SITLA.
Logical_Consistency_Report: topologically clean, 7/22/99, Arc/Info
Completeness_Report:
This coverage is based on land status and State mineral ownership data compiled by the Utah School and Institutional Trust Lands Administration (SITLA) at a scale of 1:100,000 following the "Utah Schools and Lands Exchange Act of 1998". Federal mineral ownership is based on work done in the late 1980s by the former U.S. Bureau of Mines (USBM) and updated to reflect mineral exhanges that took place in 1998 as listed above. The USBM Federal mineral ownership data is generalized to the section level.

Process_Description:
On 7/8/99 the Utah land ownership Arc/Info export file, aolsa.e00, was downloaded from the File Transfer Protocol (FTP) site at 168.178.199.148/pub (this file was updated by the Utah School and Institutional Trust Lands Administration (SITLA) in July, 1999, as indicated at this web site). The file was imported into Arc/Info and projected to geographic decimal degrees (dd) and, because of numerous intersections, cleaned with a minimum fuzzy tolerance and the poly option. After running the CLEAN command, the input and output coverages were compared in Arcedit to ensure that no line shifts resulted from CLEAN; they appeared to perfectly overlap one another. There were no label errors in the output coverage. The coverage was then clipped to the study area and an item was added according to the USGS surface and mineral management status attributing scheme, as follows --

 
Arc: additem SURF 8 8 c

 
An addititonal item, STATEMINS, was added to contain State mineral ownership information provided in the coverage from SITLA.

 
Arc: additem STATEMINS 8 8 c

 
The item SURF was populated based on the item NAMES; STATEMINS was populated based on the item MNRL. Extraneous items from the original coverage were deleted and the coverage was dissolved using the #all and poly options. This reduced the number of polygons from 9378 to 6230.

Process_Description:
A mineral ownership coverage was created for Utah by joining an INFO file that contains mineral ownership by section, to a 1:24,000-scale PLSS from the Utah School and Institutional Trust Lands Administration (SITLA). Information on the PLSS data and the Federally-owned minerals data for Utah are available from the Utah State Geographic Information Database (SGID) Users Guide prepared by the Automated Geographic Reference Center (AGRC). See the Utah AGRC web site at <URL:http://www.its.state.ut.us/agrc/>.

 
Information on Federally owned minerals was obtained from the former U.S. Bureau of Mines (USBM --- C.A. Roberts). The data is based on work done in 1988. At that time the USBM acquired land status and mineral ownership information by reading Master Title Plats and management documents. This data is more accurate than the 1:100,000-scale BLM maps published prior to 1988. The leasable minerals owned by the Federal government are generalized to the section level. As defined in this coverage, any section that contains a leasable mineral commodity that is owned by the Federal government in 50% or more of the areal extent of the section, is flagged as Federal ownership for that particular commodity for the entire section. Likewise, sections that contain a leasable mineral commodity that is owned by the Federal government in less than 50% of the areal extent of the section are flagged as nonfederal ownership for the entire section. This information is stored according to the USGS surface and mineral management status attributing scheme, in an item that was added as follows --

 
Arc: additem FEDMINS 8 8 c

 
The item FEDMINS was initially populated based on values in PLATE_II and PLATE_III of the original Federally-owned minerals coverage. The statewide coverage was then clipped to the study area and FEDMINS was updated in those areas where the SITLA land ownership and State mineral ownership coverage provided more current mineral ownership data following the "Utah Schools and Lands Exchange Act of 1998".

Process_Description:
The coverages were subsequently combined using the Arc/Info UNION command to produce an output coverage that contains both surface ownership and Federal and State mineral ownership. The coverage was then dissolved to remove extraneous section lines. The information on State mineral ownership shows where full or partial subsurface mineral rights are retained by the State of Utah. For additional information on which minerals are owned where the State retains partial subsurface mineral rights, refer to the plat book hard copy that is stored at the Utah School and Institutional Trust Lands Administration in Salt Lake City, UT.

 
Using the information stored in STATEMINS, we were able to update information in the item FEDMINS. Where the State of Utah owns ALL of the mineral rights, we populated FEDMINS to show that Federal mineral ownership is now NONE. Where STATEMINS is equal to SOME, we know that some of the mineral rights are maintained by the State of Utah and that the other mineral rights may be Federal, Tribal or private.

 
Extraneous items from the Federal mineral ownership coverage were deleted after combining it with the coverage containing land and State mineral ownership. The coverage was dissolved with the #all and poly options; this reduced the number of polygons from 19,021 to 15,409.

Process_Description:
The union of coverages of dissimilar scale produced an inordinate amount of sliver polygons. This problem was resolved by several different methods. Further processing of the integrated land ownership and State and Federal mineral ownership coverage was done with the Arc/Info ELIMINATE command. This command deletes polygons and their labels based on the options provided. For this application it was initially determined that most polygons smaller than .00001 decimal degrees were sliver polygons. This value was specified in the Arc/Info ELIMINATE command as the minimum area for polygons. This brought the number of polygons from 15,409 to 8,563.

 
Several test coverages were temporarily created to try to use the Arc/Info CLEAN command to collapse sliver polygons. These tests proved to be unsuccessful. In the process of collapsing slivers, the CLEAN command creates numerous (in this case over 400) new polygons that contain no label points and therefore have lost the attribute information (i.e., corners of polygons become collapsed). Because of the magnitude of work that would be involved in adding the attribute information back into the coverage, it was determined that the tedious process of manually editing the remaining slivers would be of equal magnitude and might possibly introduce less error. The remaining sliver polygons were therefore edited manually.

Process_Description:
The manual editing process was performed systematically by 30- by 60-minute quadrangle until all node errors and obvious polygon errors were corrected. The time involved in this manual editing process ranged from 30 minutes to 4 hours per 30- by 60-minute quadrangle. The coverage topology (the spatial relationships between connecting or adjacent coverage features) was rebuilt several times as necessary. The coverage was checked against the 1999 Utah School and Institutional Trust Lands Aministration coverage for surface and State mineral ownership accuracy and the 1988 Bureau of Mines mineral status maps for Federally-owned minerals accuracy.

 
The procedure used is as follows --

 
In Arcedit, drawsel all polygons with areas less than .00002 decimal degrees. Create a window the size of one 30- by 60-minute quadrangle. It works well on a 21-inch screen to divide the 30- by 60-minute quadrangle into twelfths to zoom in and check the data. Create further zoomed-in windows as needed for more detail of suspect slivers. In this process, other slivers that may not be highlighted (selected polygons), are also found. Proceed through the entire 30- by 60-minute quadrangle by panning across and down, minimizing windows of slivered areas. When finished analyzing the selected polygons in the entire 30- by 60-minute quadrangle, change edit feature to arc (now selected polygons disappear). Maximize the windows one by one that contain slivers; edit arcs and labels. Also select arcs that are sliver extensions of polygons. Sometimes these arcs, when selected, are found to overlap other arcs. The draw environment needs to be arc, label, node errors and sometimes arc intersects.  Set arcsnap on.  Labels help identify minute slivers that would not otherwise be detected. The arcs that make up these slivers can be selected with edit feature arc, by selecting directly on the label, deleting the arcs and subsequently deleting the labels. Always use the command intersectarcs all. Continue this process of selecting arcs, splitting where needed, reselecting, deleting, and moving nodes to close polygons where dangles are created in the process. Always display arcs and labels; they go hand in hand in defining polygons (even sliver polygons). Both need to be deleted to avoid numerous label errors that can result in incorrect attributes associated with polygons. After zooming into detected slivered areas and fixing them, gradually zoom out to facilitate identification and deletion of additional sliver problems.

Process_Description:
This data set has gone through extensive processing to eliminate slivers. Polygon topology exists and there are no label errors. It is possible that nondetection of some slivers may have occurred. Detection of additional slivers would only be possible by working with portions of this data at a larger scale, i.e., 24,000-scale. Another dissolve following manual elimination of slivers resulted in the final coverage containing 8,187 polygons (18,515 arcs). The coverage was carefully checked against the original coverages in ArcView and edited as necessary in ArcView and Arcedit. All extraneous pseudonodes have been deleted.

Attribute_Definition:

State mineral ownership, subsurface ownership

ALL ---- Utah Trust Lands maintains full subsurface mineral Rights.
SOME ---- Utah Trust Lands maintains partial subsurface mineral rights.

Many of the polygons have no value in STATEMINS. In those areas the State of Utah maintains none of the subsurface mineral rights.

Attribute:
Attribute_Label: Fedmins
Attribute_Definition:

Federal mineral ownership, subsurface ownership

COAL+ ---- Federal government maintains mineral rights for coal and other minerals.  Where Statemins = SOME, the Federal government maintains some mineral rights for coal and other minerals.  Mineral resources are frequently divided between state and Federal based on a royalty stream or a specific tonnage, thereby allowing both entities to claim some ownership of the resource.

NONE ---- Federal government maintains mineral rights for none of the minerals.

OG+ ---- Federal government maintains mineral rights for oil and gas and other minerals.  Where Statemins = SOME, the Federal government maintains some mineral rights for oil and gas and other minerals.  Mineral resources are frequently divided between state and Federal based on a royalty stream or a specific tonnage, thereby allowing both entities to claim some ownership of the resource.

OGC+ ---- Federal government maintains mineral rights for oil, gas, coal and other minerals.  Where Statemins = SOME, the Federal government maintains some mineral rights for oil, gas, coal and other minerals.  Mineral resources are frequently divided between state and Federal based on a royalty stream or a specific tonnage, thereby allowing both entities to claim some ownership of the resource.

Many of the polygons have no value in FEDMINS. In those areas the Federal government subsurface mineral rights are unknown or the Federal government holds the rights for minerals other than those considered for this study.
