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the authorities of Title V and Sec. 302(b) of Federal Land Policy and Management Act (FLPMA) (and other ROW authorities repealed by FLPMA) ,O Act of August 28, 1937, plus the Federal Highway Act and the Mineral Leasing Act. 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. 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. 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.
This data is primarily intended for depicting the ROWs and Easements on maps. All BLM planning and management actions must identify any encumbrances on the land. Existing ROWs and Easements are intersected with other resources to determine impact and/or feasibility of the proposed action. Other usage of the data may be to indicate the rights and restrictions that 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.
