Retrieve KML from Routes drawn on map using Google Map API v3.

[pradeep...@gmail.com]

I am able to get the route directions between two places on the map. There are multiple routes (PFA of the result I am getting). I want the KML file to be retrieved from those resulting routes. Can anyone help me retrieving the KML format of the routes.

I used the following code for displaying the routes.

function calcRoute() 

{

  var start = document.getElementById('start').value;

  var end = document.getElementById('end').value;

  var directionsRequest = {

      origin:start,

      destination:end,

      provideRouteAlternatives: true,

      travelMode: google.maps.DirectionsTravelMode.DRIVING,

      unitSystem: google.maps.UnitSystem.METRIC

    };

  directionsService.route(directionsRequest,

      function (response, status) {

          if (status == google.maps.DirectionsStatus.OK) {

   if(directionsDisplay != null) {

   directionsDisplay.setMap(null);

   directionsDisplay = null;

   map = null;

   }

   directionsDisplay = new google.maps.DirectionsRenderer();

            map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

   directionsDisplay.setMap(map);

            for (var i = 0, len = response.routes.length; i < len; i++) {

                new google.maps.DirectionsRenderer({

                    map: map,

                    directions: response,

                    routeIndex: i,

   draggable: true

                });

            }

alert(ctaLayer.getUrl());

          } else {

             $("#error").append("Unable to retrieve your route<br />");

          }

      }

  );

}
