 * Spatial Join is a geoprocess that tries to relate two layers


  		




  
  75
  
    
 * from its geometry field. To do that it could establish two strategies:


  		




  
  76
  
    
 * <ul>	


  		




  
  77
  
    
 *<li>


  		




  
  78
  
    
 *	Relate a geometry with the nearest geometry of the second layer


  		




  
  79
  
    
 *  (1-1 cardinality).


  		




  
  80
  
    
 * </li>


  		




  
  81
  
    
 * <li>


  		




  
  82
  
    
 *  Relate a geometry with all the geometries of second layer that verifies


  		




  
  83
  
    
 *  a spatial relationship: contained, intersects, etc (1-M cardinality).


  		




  
  84
  
    
 * </li>


  		




  
  85
  
    
 * </ul>


  		




  
  86
  
    
 * SpatialJoinVisitor is a base interface for Visitor that does the


  		




  
  87
  
    
 * process of relationship
