title: Creating Location Awareness in Website
body: <p>Hi I have created the core parts of a web app with Google Maps V3 API and Codeigniter and now I want to make the website aware of the location of the user. From my current knowledge, I will be able to get it from the GPS sensor of the user if he is on a phone/tablet with a GPS sensor, or get it from the IP address of the browser on a desktop/laptop.</p>
  
  <ol>
  <li>How do I get his location (in Lat/Lng?) from his GPS sensor on his phone?</li>
  <li>How do I get the location from his IP address of his browser</li>
  <li>I remember Firefox being a location aware browser. How do I access the location data if its firefox? Is this a viable option?</li>
  <li>Are there other methods? (Wifi, celltower triangulation?)</li>
  </ol>
