从经纬度获取海拔高度(HERE-API) [英] Getting altitude from latitude and longitude (HERE-API)

问题描述

在给定特定纬度/经度对的情况下，HERE Javascript API是否可以获取海拔高度?据我所知，map.screenToGeo()返回的地理位置仅返回纬度和经度.

Is there anyway with the HERE Javascript API to obtain an altitude given a specific latitude/longitude pair? The geo point returned by map.screenToGeo() only returns latitude and longitude as far as I can tell.

推荐答案

您无法使用HERE API做到这一点，但我可以从Google Elevation API获取该信息.

You can't do it with the HERE API, that I can see, but you can get that information from the Google Elevation API.

通过拨打GET并在查询中传递纬度和经度，您可以获取以米为单位的海平面高度:

By making a GET call and passing in the latitude and longitude in the query, you can get back the altitude from sea level in meters:

https://maps.googleapis.com/maps/api/elevation/json?locations=40.714728,-73.998672

这将返回一个像这样的json对象:

This will return a json object like this:

{
   "results" : [
      {
         "elevation" : 8.883694648742676,
         "location" : {
            "lat" : 40.714728,
            "lng" : -73.998672
         },
         "resolution" : 76.35161590576172
      }
   ],
   "status" : "OK"
}
