使用Google Places API查找最近的道路: [英] Finding nearest road using Google Places API:

问题描述

在我正在开发的Ruby应用程序中，给定点的纬度和经度，我需要找到到该点最近的道路/高速公路.

In the Ruby application which I'm developing, given latitude and longitude of a point, I need to find the nearest road/highway to the point.

有人可以告诉我如何使用Google Places API进行此操作吗?

Can someone tell me how I can go about this using Google Places API?

我尝试使用'types:"route"'参数给定一定的半径并找到道路，但输出为零结果".

I have tried giving a certain radius and finding the roads using the 'types:"route"' parameter but it gives me "Zero results" as the output.

推荐答案

Google Places API并非旨在返回附近的地理位置，而是旨在返回附近场所的列表，最多可返回两个 locality 或 political 类型的结果可帮助识别您要执行位置搜索请求的区域.

The Google Places API is not designed to return nearby geographical locations, it is designed to return a list of nearby establishments and up to two locality or political type results to to help identify the area you are performing a Place Search request for.

您要的功能可以通过 Google Geocoding API 来实现lat，lng到HTTP反向地理编码请求的 latlng 参数:

The functionality you are requesting would be possible with the Google Geocoding API by passing the lat, lng to the latlng parameter of the HTTP reverse geocoding request:

http://maps.googleapis.com/maps/api/geocode/json?latlng=41.66547000000001,-87.64157&sensor=false
