What does this data set describe?

BLM OR Visual Resource Management Publication Polygon

vrm_pub_poly: Publication dataset showing Visual Resource Management (VRM) classes for BLM-managed lands in Oregon and Washington. VRM classes are determined through the landuse planning process.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • GT-polygon composed of chains (9133)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 2e-008. Longitudes are given to the nearest 2e-008. Latitude and longitude values are specified in Decimal Degrees.

      The horizontal datum used is D North American 1983.
      The ellipsoid used is GRS 1980.
      The semi-major axis of the ellipsoid used is 6378137.0.
      The flattening of the ellipsoid used is 1/298.257222101.

  7. How does the data set describe geographic features?

    The dominant (strongest, least likely to change) reason for the particular designation.  The attribute identifies the spatial entity that was used to create the polygon and therefore acts like polygon feature-level metadata. (Source: Bureau of Land Management)

    The assignment of the four VRM classes is ultimately based on the management decisions made in Resource Management Plans. (Source: Bureau of Land Management)

    VRM 1
    The objective of this class is to preserve the existing character of the landscape.  This class provides for natural ecological changes; however, it does not preclude very limited management activity.  The level of change to the characteristic landscape should be very low and must not attract attention.  Class I areas include wilderness areas, wild portions of wild and scenic rivers, and other congressionally and administratively designated areas where decisions have been made to preserve a natural landscape.
    The objective of this class is to retain the existing character of the landscape.  The level of change to the characteristic landscape should be low.  Management activities may be seen, but should not attract the attention of the casual observer.
    VRM 3
    The objective of this class is to partially retain the existing character of the landscape.  The level of change to the characteristic landscape should be moderate.  Management activities may attract attention but should not dominate the view of the casual observer.
    VRM 4
    The objective of this class is to provide for management activities which require major modification of the existing character of the landscape.  The level of change to the characteristic landscape can be high.  These management activities may dominate the view and be the major focus of viewer attention.
    No VRM
    BLM administered land where no VRM Classification has been made.

    Polygons show the boundaries of different VRM Class areas and attributes give the Class number plus the dominant reason for the Class designation.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

    Horizontal accuracy determined by coincidence with VRM lines.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Data is currently available for the Burns, Coos Bay, Eugene, Lakeview, Medford, Prineville, Roseburg, Salem, and Vale Districts.

  5. How consistent are the relationships among the observations, including topology?

    Visual Resource Management (VRM) consist of unique, non-overlapping polygons.
