BLM OR Resource Area Boundary Polygon

Frequently-asked questions:


What does this data set describe?

Title:
BLM OR Resource Area Boundary Polygon

Abstract:
RAB_POLY: This theme shows line representation of jurisdictional Bureau of Land Management Resource Area perimeters for Oregon and Washington.

Supplemental information:
BLM (Bureau of Land Management) RAB (Resource Area Boundary) Boundary definitions reference features or positions depicted in other GIS layers. The data from those layers is copied to create the Resource Area Boundary layer. Vertical integration with other layers will be maintained to ensure the most accurate representation. A published revision of the Department Manual's Part 305: Departmental Science Effects, Chapter 3: Integrity of Scientific and Scholarly Activities (305 DM 3), effective December 16, 2014, is available online at http://elips.doi.gov/ELIPS/DocView.aspx?id=4056. Scholarly information considered in Departmental decision making must be robust, of the highest quality, and the result of as rigorous scientific and scholarly processes as can be achieved. Most importantly, it must be trustworthy. This policy helps us to achieve that standard (http://www.doi.gov/scientificintegrity/index.cfm)
