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the authorities of Title V and Sec. 302(b) of Federal Land Policy and Management Act (FLPMA) (and other ROW authorities repealed by FLPMA) ,O Act of August 28, 1937, plus the Federal Highway Act and the Mineral Leasing Act.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. |
