I believe that you know that well.

Although it's currently down, I guess that's the site where the information came from.

For your information http://www.gpsvisualizer.com/ properly interprets google maps encoding. As an output I've receive series of GPS coordinates. So there is a method to decode it but question is how

That's a good hint. I saw GPS coordinates in the JavaScript output of the site - probably they internally open a browser/JavaScript interpreter with the URL and use the Google Maps API to extract the data from the page?
