   I don't know the precise or official definition, but I can give you an   
   educated guess.   
      
   GPS uses only the GPS receiver.   
      
   Coarse uses only the GSM network and WiFi/IP guessing by google. Ie,   
   Cell, GeoIP and Wifi location. The error can be kilometres, thus coarse   
   location. Sometimes it is surprisingly precise. Also called "low battery   
   mode" or something similar. It is the one I use.   
      
   Fine location uses both methods. I guess that by having a coarse   
   location first, and by knowing the timetable of the satellite passes, it   
   decides what satellites to search for, instead of trying all of them.

   LOL. So that you choose always the preferred method, "fine location".

   Designer choice. What a question!

   Well, it is just an accurate description of what it does. Wifi and Cell   
   is what together do "coarse location". Again, designer choice to list   
   them all instead of the switch name.
