esmtrow_poly: This data set represents areal ROWs and Easements. Rights-of-Way and Easements that are linear in nature, such as roads or power lines, have associated widths that can be used to buffer the linear features and create polygon areas. Area entities include these linear buffer features as well as ROWs and Easements described by parcels. These are a portion of the total ENCUMBRANCE data category which includes entities about rights and restrictions. The rights and restrictions relate to the use of federal public land or to the use of non-federal land by the federal and public entities. Example uses might be construction or simply crossing the land. Rights-of-way in this data set include ROW and other land use authorizations issued by the United States under the authorities of Title V and Sec. 302(b) of Federal Land Policy and Management Act (FLPMA) (and other ROW authorities repealed by FLPMA) ,O Act of August 28, 1937, plus the Federal Highway Act and the Mineral Leasing Act. Easements in this data set are the spatial representation of partial interests in non-federal land acquired or reserved by the United States. In general, ROWs are rights granted by BLM and Easements are rights granted to BLM, but there are exceptions. The data set includes both linear and area entities. This data set is not intended to include all ROWs and Easements, but only those most important for common GIS spatial analysis. In addition, only basic information about the ROWs and Easements is provided. Details and the complete rights and restrictions history are found in the authoritative sources: Master Title Plats, case file records, and the LR2000 database.

esmtrow_arc: This data is a linear representation of Right of Ways (ROWs) and Easements for the State of Oregon. These are a portion of the total ENCUMBRANCE data category which includes entities about rights and restrictions. Rights-of-way in this data set include ROW and other land use authorizations issued by the United States under the authorities of Title V and Sec. 302(b) of Federal Land Policy and Management Act (FLPMA) (and other ROW authorities repealed by FLPMA) ,O Act of August 28, 1937, plus the Federal Highway Act and the Mineral Leasing Act.

Details and the complete rights and restrictions history are found in the authoritative sources: Master Title Plats, case file records, and the LR2000 database. Easement and ROWs are legal entities. They are often related to physical entities such as roads and power lines. The Easement or ROW is described in relation to the constructed entity, but is not necessarily identical.

SUBSURFACE_RIGHTS_POLY: This theme portrays information related to the Public Land Survey System, and subsurface minerals of lands in the states of Oregon and Washington.

LTZ_POLY: This feature class represents BLM Land Tenure Zones (LTZ) for Oregon and Washington, areas (zones) on BLM lands as Retention/Acquisition, Exchange, or Disposal of lands under BLM jurisdiction. The LTZ polygons do not identify actual acquisition or disposal actions, but rather the zones of potential land tenure adjustment as determined through the land use planning process. All BLM lands are covered by these zones. For detailed information on individual parcels contact the relevant BLM Oregon district staff. This data conforms to the 'Land Tenure Zones Spatial Data Standard 20131130. 'http://www.blm.gov/or/datamanagement/index.php'

OWNERSHIP_POLY: This theme portrays information related to surface jurisdiction, and land category of lands located in the states of Oregon and Washington.

MINSTIP_POLY: This dataset applies to BLM-administered lands containing valuable minerals and categorized in the U.S Code of Federal Regulations or by official U.S. Department of Interior policy as Open, Closed, or Restricted to mining or leasing. And it further labels restrictions, if any, by type (e.g., seasonal, no surface occupancy, etc.). Restrictions are formalized by use of “Mineral Stipulations” as determined through the Land Use Planning Process and defined in the resultant Resource Management Plan (RMP). In addition, informal BLM email communication between Tim Barnes (OR 936.2) and Jim Perry (WO 310), dated August 9, 2013, concluded, by reference to WO IM No. 2012-044, “BLM National Greater Sage-Grouse Land Use Planning Strategy”, that RMPs developed after 2013 should also apply mineral stipulations to split estate lands (BLM subsurface jurisdiction but non-BLM surface). The three categories of minerals covered under Minerals Stipulations are: Locatable, generally the metallic and industrial minerals (subject to the General Mining Law of 1872, as amended); Leasable, generally fluid minerals (oil and gas and geothermal resources) and certain other minerals (subject to the various Mineral Leasing Acts); and Salable, generally sand and gravel (subject to mineral materials disposed of under the Materials Act of 1947, as amended). For locatable minerals, the stipulation choices for an area might be “Withdrawn” if it is withdrawn from mineral entry or “OpenWSA” if the area is open to mining claim location subject to Wilderness Study Area (WSA) Non-impairment criteria or “Open”. The stipulations choices for salable minerals are “Open” (available for mineral materials), “OpenCSU” if the area is open but with (Conditional Surface Use) special seasonal or other stipulations such as buffer zones around sage-grouse leks or archeological sites, or “Closed” (not available for mineral materials). The stipulation choices for leasable minerals are “NoLease” if the area is withdrawn or otherwise not available for leasing, “OpenCSU” if the area is open but with (Conditional Surface Use) special seasonal or other stipulations such as buffer zones around sage-grouse leks or archaeological sites, “OpenNSO” if the area is open but with No Surface Occupancy allowed or simply “Open” with standard stipulations.
