问题描述
我使用Google Maps v3，并且需要为我的地图添加不同区域的边框线。例如，在Google地图中，所有美国国家边界都会自动显示。我需要为不同的国家做同样的事情。例如，显示英格兰的所有城市边界。
如何使用Google Maps API v3做到这一点？

推荐答案
您可以使用Google地图中提供的 ，通过查看了解更多信息，然后创建v3 。构成国家，州和城市边界的Lat-Lng坐标不是在Google地图中直接提供的，但有一些支持数据可用：
You can use the KML support that is provided in Google Maps, learn more by reviewing the KML Introduction, and then create v3 KmlLayer. The Lat-Lng coordinates that make up the country, state, and city boundaries is not provided out-of-the-box in Google Maps, but some of supporting data is available:
- 由Valery Hronusov创建
- 由Filipumme创建
- 可从Google下载
- 有一些额外的城市数据可供使用，并且需要在线搜索才能找到
- KML of the World Countries as created by Valery Hronusov
- KML of the World Capitals as created by Filipumme
- KML of the US States is available for download from Google
- Some additional city data is available, but that is often city-by-city and requires online searching to find
大部分数据也可以公开用于动态检索，如，但在这种情况下，您将使用共享的公共数据。我使用KML来处理这种类型的事情，因为我希望拥有数据的内部副本，保持对数据的完全控制，并且有能力进行自己的更改或更新。
Much of this data is also available publicly for dynamic retrieval as Fusion Tables, but in that case, you will be using shared public data. I use KML for this type of thing, because I want to have internal copies of the data, maintain full control over the data, and have the ability to make my own changes or updates.
