jamesrt:tdgeek: How does Apple or Google Maps on my laptop at home know exactly where I am on the map?
I believe it's through aggregated data-mining and/or data collection.
For example, if you've ever connected to a WiFi point in your house from a mobile phone; the phone manufacturer has the ability to tie together the router MAC/External IP of the ISP/internet connection to the GPS and/or Triangulated Cellphone tower location of the phone. Once they've done that, then anything hitting the internet from that External IP can be assumed to be in that location - hence, your laptop is located.
I don't believe Apple or Google will necessarily be able to triangulate based on cell-tower data.
There's parameters in there that only your mobile carrier will have ready access to.
But your device GPS? You betcha.
