Notice that your iPad calls it "Location Services" and not "GPS".  So, 
sometimes that includes your GPS *if* you have one.  If not, then it 
just includes the wi-fi and cellular methods of determining your 
position.  This morning when I look at Google Maps many of those blank 
spots of traffic are filled in.  Why?  Because there are more people 
traveling today on those routes with their cellphones turned on 
anonymously reporting back to Google where they are and how fast they're 
going.  No cameras needed.

If you turn on location services and try to use Google Maps it will 
probably figure out generally where you are *as long as* it has enough 
data about your wi-fi connection and/or IP address. Your iPad will 
report back information about your hotspot and any other wi-fi signals 
it picks up.  Based upon information that is stored in Google's 
databases it will try to figure out where you are.  Now go drive around 
out in the country away from any wi-fi hotspots (or fly around in the 
air a mile above the ground) and see if it can determine where you 
are...won't work.

See?  No cameras needed.
