title: Extract Data from Google Map Result
body: <p>I want to create a custom application that aggregates locations I find using Google maps into a custom map.   For a couple of reasons, google's save to map feature is insufficient for my needs. </p>
  
  <p>I'm wondering if there's a way I can create a browser extension that will let me pop up a custom form and then transmit the form data and the lon/lat data to my own server.   </p>
  
  <p>I can figure out most of the pieces of this myself, except for extracting the longitude and latitude data.  Is this stored anywhere in the dom or window object that I can query when looking at a marker or the location details?  </p>
