  5. What is the general form of this data set?

    Geospatial_Data_Presentation_Form: vector digital data

  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):

      • G-polygon (0)
      • Label point (89)
      • GT-polygon composed of chains (89)
      • Point (761)

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

      The map projection used is Albers Conical Equal Area.

      Projection parameters:
      Standard_Parallel: 43.000000
      Standard_Parallel: 48.000000
      Longitude_of_Central_Meridian: -120.000000
      Latitude_of_Projection_Origin: 34.000000
      False_Easting: 600000.000000
      False_Northing: 0.000000

      Planar coordinates are encoded using coordinate pair
      Abscissae (x-coordinates) are specified to the nearest 0.000000
      Ordinates (y-coordinates) are specified to the nearest 0.000000
      Planar coordinates are specified in meters

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

  7. How does the data set describe geographic features?


    Internal feature number. (Source: ESRI)

    Sequential unique whole numbers that are automatically generated.

    Feature geometry. (Source: ESRI)

    Coordinates defining the features.

    Area of feature in internal units squared. (Source: ESRI)

    Positive real numbers that are automatically generated.

    Perimeter of feature in internal units. (Source: ESRI)

    Positive real numbers that are automatically generated.

Why was the data set created?

Inventoried Roadless Area Boundary (RAI)
Message from Paul Cuddy, Ochoco National Forest Planner regarding RAI (Inventoried Roadless Area) It is the official layer and has replaced the other two layers (RAB and RAC). The only reason to use these other coverages is if we are doing some analysis to determine if we have some"unroaded" areas(areas of sufficient size and integrity that they have similar attributes as the Roadless Area) adjacent to the Roadless area. These other layers may be of some value in answering that question, but I would hope that we would have site-specific data (roads or not, amount of harvest activities, etc.) that would be far more useful in addressing the "unroaded" question than maps(the other two coverages) generated 20 to 30 years ago.
