Get latitude longitude from google maps itinerary


I would like to know if someone can help me about this point.

I have a script based on google maps who calculate itinerary. I would like to know if it is possible to get an array of this itinerary with the latitude-longitude every 1 kilometer for example. If the itinerary is 100 kilometers long, i'll get an array with 100 datas

<ul><li>(latitude,longitude, 0)</li> <li>(latitude,longitude, 1)</li> <li>(latitude,longitude, ...)</li> <li>(latitude,longitude, 99)</li> </ul>

I need it because i would like to propose points interest near an itinerary. Example: <a href="https://roadtrippers.com/" rel="nofollow">https://roadtrippers.com/</a>

<ol><li>You select the start of your trip</li> <li>You select the destination of your trip</li> <li>It suggest what you can do near your itinerary</li> </ol>


The DirectionsService class will give you a response with a <a href="https://developers.google.com/maps/documentation/javascript/reference#DirectionsResult" rel="nofollow">DirectionsResult object</a>. This object has a property called overview_path that gives, from the docs:


An array of LatLngs representing the entire course of this route. The path is simplified in order to make it suitable in contexts where a small number of vertices is required (such as Static Maps API URLs).


You can use these to perform places searches (with the <a href="https://developers.google.com/maps/documentation/javascript/places" rel="nofollow">places library</a>) to get points of interest, etc, within a radius from each LatLng that's returned in the overview_path array.


var request = { origin: start_point, destination: end_point, travelMode: google.maps.TravelMode.DRIVING }; var directionsService = new google.maps.DirectionsService(); directionsService.route(request, function(response, status) { if (status == google.maps.DirectionsStatus.OK) { var path = (response.routes[0].overview_path); } });
