我花了一个下午的时间寻找世界上最重要的城市的开放数据库，

它们中的大多数都是高级的，价格大约是 400 美元，但是由于我正在从事一个开源项目，我想使用开放数据，有什么地方可以下载重要城市的名称吗？

我找到了开放的街道地图，但它是 16gb 的东西，例如节点关系，但我只需要城市名称和坐标，

非常感谢你，

这可能比您想要的更多，但您可以使用 Overpass API 来查询所有具有["place"="city"].

例如，访问http://www.overpass-api.de/query_form.html并输入以下内容：

node
  ["place"="city"];
out body;

用于 XML 输出，或以下用于 JSON：

[out:json];
node
  ["place"="city"];
out body;

输出需要一分钟左右才能返回给我（它返回了 5,000 多个节点），但如下所示：
