Frequently-anticipated questions:

What does this data set describe?

Title: waterbody
Abstract:
A waterbody is a naturally occurring or constructed hydrographic feature such as lake/pond, swamp/marsh, double line streams, and other 2 dimensional hydrographic features. The WB features are further classified by periodicity and or classification (i.e. perennial or intermittent). When available, official geographic names are included.
Supplemental_Information:
This dataset was generated by combining multiple datasets from the Ochoco and Deschutes National Forest.
From the Ochoco: LAKE (lakes, reservoirs, and ponds -- originally generated from CFF's), RIVER (River - double line streams -- originally generated from CFF's), and MARSH (wetlands and marshes -- originally generated from CFF's).
From the Deschutes: LAKE (lakes, ponds and reservoirs -- originally generated from CFF's, and updated with field data and aerial photo interpretation on Crescent District only), STREAM-P - Double line stream data generated from CFF's, and WETLAND (wetlands and marshes -- generated from CFF's, updated with district aerial photo interpretation and field data on Crescent District only, and wet plant associations -- see Hall 1998 Pacific Northwest Ecoclass Codes for Plant Associations).
Supplemental Information: For the Ochoco wet plant associations were added to supplement the marsh layer -- (see Hall 1998 Pacific Northwest Ecoclass Codes for Plant Associations).

  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 (5899)
      • GT-polygon composed of chains (5899)
      • Point (4)

    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.
