location wrong on ipad and how do i fix it

Is your iPad wifi only or wifi + cellular?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

iOS 7: Understanding Location Services

Maps, directions, and location-based apps depend on data services. These data services are subject to change and may not be available in all geographic areas, resulting in maps, directions, or location-based information that may be unavailable, inaccurate, or incomplete.

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.
