Description: This theme shows line representation of jurisdictional Bureau of Land Management Resource Area perimeters for Oregon and Washington. Layers are duplicated with symbology changes at the different scale levels. BLM Management areas are contiguous across the United States. The line layer defines the features that form the boundaries.
Purpose: This data set is used for depicting the Resource Area Boundary on maps. Resource Area boundaries are dissolved to form District boundaries. Polygons created from the data are used for various analytical purposes, including clipping data and calculating acreage. Polygons are in the label layers.
Description: admu_ofc_arc: Line data for Oregon BLM Administrative Units. The Administrative Units (ADMU) data standard contains requirements for administrative boundaries within the Oregon/Washington (OR/WA) Bureau of Land Management (BLM). The OR/WA BLM State Office jurisdiction consists of Districts sub-divided into Field Offices. This dataset was formerly known as Resource Area Boundaries (RAB). The OR/WA BLM administrative jurisdiction encompasses the entire political States of Oregon and Washington. A BLM District or Field Office may cross the political boundary between those States. The dataset includes boundary lines depicting official BLM District boundaries, as approved by the Washington Office, and those depicting administrative BLM Field Office boundaries, as approved by the OR/WA BLM State Director, where the boundary lines are not coincident with the official District line.
