"If you have the WiFi-only iPad (which does not have GPS) your location is determined by the mapped location of nearby WiFi routers.
Without GPS location-finding is done by using a Apple location database which contains the MAC addresses of routers and their physical location. A MAC address is a unique number which is built-in to all network devices when manufactured.
The Apple database is built and updated by Apple GPS-enabled devices (primarily iPhones) actually seeing routers and then adding/updating the router's locations into the database.
Note to be used for location determination, a device does not need to be actually connected to a router, it just has to see the router. More precise location determination can be done if several nearby routers can be seen. When a router is moved from one location to another erroneous locations can sometimes be reported until the router's location is corrected in Apple's database."
TLDR version: "Your location is determined by wifi routers."

This is about the iPad Maps program:
'My Location' lists the wrong address when I'm at home. I don't know how accurate it should be but the address is 6901 instead of 6975. I just realized why I can't specify the address because it wouldn't be correct if I were somewhere else. Only I haven't taken my iPad anywhere else except once. :-) Is tere any way to get 'My Location' to be more accurate when I'm at home?Presuming you have a cellular-capable device, take it outdoors where it can see the GPS satellites, and try again.My location when in my house is typically off by over a mile. I think because my Wifi is only registered to a zip code.
