反向地理编码：响应中城市与国家相同？

Question

我在 reverse geocode API 中使用 HERE 地图，一位来自巴基斯坦的用户发送了一份报告，称国家和城市都在对于坐标对 31.522473692893982, 74.33312326669693，报告为 "Pakistan"。我仔细检查并发现了同样的错误；这是回应：

{"items":[{"title":"Pakistan, Pakistan","id":"here:cm:namedplace:22928320","resultType":"locality","localityType":"city","address":{"label":"Pakistan, Pakistan","countryCode":"PAK","countryName":"Pakistan","city":"Pakistan"},"position":{"lat":33.70964,"lng":73.07545},"distance":0,"mapView":{"west":60.87305,"south":23.7033,"east":77.13585,"north":37.07742}}]}

countryName 和 city 都被报告为 "Pakistan" – 这与事实不符，并且让用户感到困惑。这也很难在我的应用程序中以编程方式处理 - city 如果不存在则应该为空白，我可以为此编写检查代码。

以上是世界第18大城市Lahore的坐标！我在使用坐标对 31.5204, 74.3587 时遇到同样的错误——Google 报告为拉合尔的 center。至少，HERE 没有理由不把这个大城市弄好，即使是在地方层面。

谢谢，

Answer 1

这确实令人困惑。请尝试使用 Places API。对于您使用的坐标，它 returns 拉合尔。

GET https://places.ls.hereapi.com/places/v1/discover/search?
  at=31.522473692893982,74.33312326669693&
  q=31.522473692893982,74.33312326669693&
  apikey={{apiKey}}

结果

对于巴基斯坦，HERE Reverse Geocoder V7 API 目前只能访问入口地图，这是一个内容占位符，而不是一张有价值的地图。计划到 2020 年增加巴基斯坦的地图覆盖范围。
