Frequently-asked questions:


What does this data set describe?

Title:
BLM OR Visual Resource Inventory Publication Polygon

Abstract:
vri_pub_poly: Publication dataset showing Visual Resource Inventory (VRI) classes for BLM-managed lands in Oregon and Washington. The classes are based on scenic quality, sensitivity level, and distance zones.

Supplemental information:
BLM - Bureau of Land Management

  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 (9676)

    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.

    VRI_CLASS
    VRI Classes are the result of the evaluation of an area for it's visual potential based on several criteria including scenic quality, sensitivity level, and distance zones. (Source: Bureau of Land Management)
                      

    ValueDefinition
    I
    Assigned to all special areas where the current management situations require maintaining a natural environment essentially unaltered by man.
    II
    Assigned where scenic quality is highest, A, or where the scenic quality is B and the distance zone is foreground/middleground.
    III
    Assigned where scenic quality is B, distance zone is background or seldom seen and sensitivity is High or where sensitivity is Medium but the distance zone is foreground/middleground.
    IV
    Assigned to areas that don't meet the criteria for I, II, or III.

    VRI_SCENIC
    A code to denote most (A), moderately (B), or least (C) scenic quality based on factors such as landform, vegetation, water, color, influence of adjacent scenery, scarcity, and cultural modifications. (Source: Bureau of Land Management)
                      

    ValueDefinition
    A
    Most Scenic; score of 19 or more using procedures in BLM Handbook H-8410-1
    B
    Moderately Scenic; score of 12-18 using procedures in BLM Handbook H-8410-1
    C
    Least Scenic; score of 11 or less using procedures in BLM Handbook H-8410-1

    VRI_SENSITIVITY
    The visual sensitivity of the area being inventoried based on type of users, amount of use, public interest, adjacent land uses, and special areas. (Source: Bureau of Land Management)
                      

    ValueDefinition
    HIGH
