谷歌地图API。到达该国所在的大陆

时间：2014-10-03 17:34:04

标签： api google-maps maps

google API有一个简单的查询

https://maps.googleapis.com/maps/api/geocode/json?address=&components=country:Russia&language=ru&key=MY_API_KEY

响应包含边界，位置和完整地址（例如 - 俄罗斯）

但我现在需要 - 俄罗斯 - ＆gt;欧洲，美国 - ＆gt;北美，埃及 - ＆gt;非洲。

怎么做？！

使用Google API进行地理编码。

"address_components"中的一个条目应该看起来像[ "country", "political" ]，例如：

{
  "long_name" : "United States",
  "short_name" : "US",
  "types" : [ "country", "political" ]
},

使用其"short_name"值并根据以下内容将其转换为非洲大陆：

要获取大陆，请在输入坐标中使用多边形分析中的点（从查找地址开始），您可以从此FusionTable containing the continent data获取该大陆。

使用OpenCage Geocoder API服务，它拥有大陆的一个值。

https://geocoder.opencagedata.com/api

  

_type的可能值包括（但不限于）：建筑物，道路，村庄，社区，城市，县，邮政编码，州州，州，地区，岛屿，国家，大陆，虚构，未知

您可以使用http://country.io/continent.json将国家/地区ISO2代码映射到大陆ISO2代码。

使用此数据集https://github.com/datasets/continent-codes/blob/master/data/continent-codes.csv

将大陆ISO2代码转换为其代码

国家ISO2代码到大陆ISO2代码{"BD": "AS", "BE": "EU", "BF": "AF"...}
