title: Google Maps API V3: How to get region border coordinates (polyline) data?
body: <p>I'm trying to get (specified) region borders as GMaps coordinates (to form a polyline) from Google Maps. Is this possible in some way? (either from maps.google.com or my own GMaps in my own domain).</p>
  
  <p><strong>Note:</strong>
  I know you can draw/outline regions manually with tools intended for it (like <a href="http://www.birdtheme.org/useful/v3tool.html" rel="noreferrer">http://www.birdtheme.org/useful/v3tool.html</a>), but covering a large region ACCURATELY is a ton of work.
  The draw-it-yourself answer is not an option in this case.</p>
  
  <h2>Example:</h2>
  
  <ol>
  <li><a href="https://maps.google.com/" rel="noreferrer">https://maps.google.com/</a> -> type in "Uusimaa, Finland"</li>
  <li>You can see the pink-ish border that outlines the wanted region</li>
  <li>That border is the polyline that I need the coordinates of</li>
  </ol>
  
  <h2>Requirements:</h2>
  
  <ul>
  <li>Extract the region data coordinates (if available) from a given search (as in the example)</li>
  <li>If the previous is not possible, a source to an ACCURATE map of the region "Uusimaa, Finland" is required (plain googling did not yield needed results).</li>
  </ul>
