Perhaps someone with greater expertise.... The new maps in 10.9 is interesting. Using on an iMac with fast broadband, good GPS signal, wifi, living in a major city.... still the blue dot for my location is about 200 metres from where I am. What degree of accuracy should one expect from Maps?


iMac (27-inch, Late 2012), OS X Mavericks (10.9)

    Maps on a computer doesn't have GPS to rely on.  It uses a WiFi location database where it looks up nearby WiFi access points and tries to triangulate where you are.

     

    For me, at home, it gets pretty close.  200 meters out is quite a ways but you can't expect pinpoint accuracy because computers don't have WiFi and thus Maps is relying on info that's not dead-on accurate.

    Aha, did not know that about GPS but now you write it, it is perfectly logical. I should therefore have a much better result with my iPhone - but interestingly not with an iPad that is wifi only. Really good to know. thanks

    That's exactly correct.  Cheers.
