Can't Apple replace the maps with google maps with an iOS update? They should if google maps are much better.
In an ideal World the user would have the option to choose the source of the imagery but I'd hazard a guess it would become a conflict of interest on grounds of intellectual property. All the mapping applications I have on my iPad, other than Google Earth, Google Maps, Commander Compass, utilise Apple Maps. These include Flightradar24, WindAlert, eIAIP, and of course DJI's Datalink and Inspire Pilot applications.
I suppose it boils down to what you want from either Apple or Google maps. Many are in favour of Apple's system as it is more suited for such things as car navigation and travel on public transport, apparently. Where as Google is more up to date on its image acquisition and is used extensively for educational and scientific purposes. This is why I personally think that for autonomous flight applications, if DJI intend to make this available on the inspire at a later date, that the Android platform would be more suitable. As I say it's just a personal thing for me as currently DJI's Datalink system is just a novelty item due to the limitations of their iOS app and my current preference for autonomous flight is with APM based systems which run happily on Android and use Google Maps.
Apologies for going off track somewhat.
