Checking my location using the Maps app, I see that it identifies my location incorrectly by hundreds of miles.

What determines the accuracy of the location as identified by the Maps app?

It maybe guessing your location based on the where the server of your ISP is located. I am based in Mumbai and my location shows somewhere in the eastern part of the company. The main server of the ISP is based there. – Fasih Khatib Nov 6 '12 at 12:30

The accuracy largely depends upon the hardware you are running on, and your network connections:

  1. GPS and A-GPS have a resolution of 5-7m at best
  2. Wireless Network-based resolution is usually a few hundred metres.

If you are on a device without the above hardware, you will see IP-based positioning, which could be very inaccurate, as your ISP's internet-facing server could be some-place else entirely.

Correct, I was using IP based positioning. I see marginal difference with Wifi. thanks! – A.Antri Oct 31 '12 at 12:59
