从谷歌地图行程获取纬度经度 [英] Get latitude longitude from google maps itinerary

问题描述

我想知道是否有人可以帮助我解决这一点.

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

我有一个基于谷歌地图的脚本来计算行程.我想知道是否有可能获得此行程的数组，例如每 1 公里的经纬度.如果行程是100公里，我会得到一个有100条数据的数组

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

• (纬度，经度，0)
• (纬度，经度，1)
• (纬度，经度，...)
• (纬度，经度，99)

我需要它，因为我想在行程附近提出兴趣点.示例:https://roadtrippers.com/

I need it because i would like to propose points interest near an itinerary. Example: https://roadtrippers.com/

1. 您选择旅行的起点
2. 您选择旅行的目的地
3. 它建议您在行程附近可以做什么

推荐答案

DirectionsService 类会给你一个 DirectionsResult 对象.这个对象有一个名为 overview_path 的属性，它从文档中给出:

The DirectionsService class will give you a response with a DirectionsResult object. This object has a property called overview_path that gives, from the docs:

代表这条路线整个路线的 LatLng 数组.这路径被简化，以使其适用于以下情况需要少量顶点(例如静态地图 API 网址).

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).

您可以使用这些来执行地点搜索(使用地点库)从 overview_path 数组中返回的每个 LatLng 获得半径范围内的兴趣点等.

You can use these to perform places searches (with the places library) to get points of interest, etc, within a radius from each LatLng that's returned in the overview_path array.

示例:

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);
  }
});
