You really missed the point.  Think about it like this.  If you were to 
pick up a map and point out roughly where you took some photo of your 
kids in a park (or whatever) and you wanted to pick up a pen and mark 
the location, you're not going to sit there and carefully outline the 
polygon shape of the park, you're going to draw something like an X or a 
circle to show the rough location.  That's the concept that this thread 
is discussing.
