  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 (95)
      • Label point (1)
      • GT-polygon composed of chains (1)
      • Point (319)

    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 0.000125.
      Ordinates (y-coordinates) are specified to the nearest 0.000125.
      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.

      Vertical coordinate system definition:
      Altitude system definition:
      Altitude resolution: 0.000122
      Altitude encoding method: Explicit elevation coordinate included with horizontal coordinates
