Even without a GPS, a WiFi only iPad still can determine it's location.

Google started the WiFi access point mapping project with their street view
cars. In addition to taking pictures, they were logging every access point
they found.  People complained and google stopped logging the WiFi access
points. Now they do it with separate vehicles.  Cute, huh?

Bottom line is there is a database(s) with almost every access point and
its location. So when you connect to an access point, there's about a 98%
chance the AP is logged and your iPad now knows where it is.

The apps want to be able to do things like report your location so it can
show you ads relevant to your location, or show you current weather in
WeatherBug without you having to enter your location.

For Google maps traffic is pulled from everyone that has a GPS enabled cell
phone and has opted in to location services.
