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):

      • String (535)
      
      
   2. What coordinate system is used to represent geographic features?
      
      
      The grid coordinate system used is Universal Transverse Mercator

      
      Universal Transverse Mercator

      UTM zone number: 11

      Transverse Mercator projection parameters:

      Scale factor at central meridian: 0.999600

      Longitude of central meridian: -117.000000

      Latitude of projection origin: 0.000000

      False easting: 500000.000000

      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.

      
      Vertical coordinate system definition:

      Altitude system definition:

      Altitude resolution: 1.000000

      Altitude encoding method: Explicit elevation coordinate included with horizontal coordinates
