   The Google Maps app was on iOS long before Apple Maps even existed.   
      
   As you noted, the iOS platform has far less map app functionality than does   
   the Android platform (free offline routing-capable topographic maps being   
   one which hits me hard since I hike a lot), in the case of *road* maps,   
   while there is still always going to be far less app functionality on the   
   iOS platform than on Android, the huge major players are the same (e.g.,   
   Google, CoPilot, Waze, Maps.me, Google Earth) but almost all the major and   
   minor free online and offline no-registration map players simply don't   
   exist on iOS - they exist only on Android.

   I would have thought the Google Maps on iOS uses the same techniquest that   
   it uses on Android, which is to utiltize whatever it can from GPS (which in   
   this case, doesn't exist), and BSSIDs (if the WiFi is turned on), and any   
   Internet-available geolocation information (which doesn't exist in this   
   case unless the tablet is connecting fleetingly to wide-open unsecured   
   access points), and, potentially, an offline BSSID:location lookup *inside*   
   of the map database itself.   
      
   I suspect that the Google Maps app *is* making use of an offline   
   BSSID:location lookup *inside* of the map database itself, but I don't know   
   how to prove that just yet, and nobody here has provided any references   
   that back up that assumption anyway.
