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 (36863)
      
      
   2. What coordinate system is used to represent geographic features?
      
      
      The map projection used is Transverse Mercator.

      
      

      Projection parameters:

      Transverse Mercator

      Scale factor at central meridian: 0.999600
