title: Finding intermediate Lattitude Longitude between two given points
body: <p>I am provided with this information - </p>
  
  <ol>
  <li>Lat-Long of source</li>
  <li>Lat-Long of destination</li>
  </ol>
  
  <p>I need to find the Lat-Long pairs on the path from source to destination. These Lat-Long pairs must differ from each other by some given granularity.</p>
  
  <p>Is there some Google API using which I can get this information ?</p>
