Google map divided in regions with color and in subregions
提问by Kashif
I need to divide USA map into political boundaries. i.e. states and in seven Regional boundaries on Google map. Each region will have its own color. Example, California, Hawaii, Nevada, Utah, Arizona and Colorado (Southwestern US) will all be same color. Political boundaries will also be on map along with regional boundaries. On national view only regional names should be visible and no state name. On zooming in to region state names will be shown, no city name should be visible either I zoom in or out.
我需要将美国地图划分为边界。即州和谷歌地图上的七个区域边界。每个区域都有自己的颜色。例如，加利福尼亚、夏威夷、内华达、犹他、亚利桑那和科罗拉多（美国西南部）都将是相同的颜色。边界也将与区域边界一起出现在地图上。在国家视图中，只有地区名称应该可见，而没有州名称。在放大到区域状态名称时将显示，无论是放大还是缩小，都不应看到城市名称。
Can you please help me understanding that from where should I start? Links? Tutorial?
你能帮我理解我应该从哪里开始吗？链接？教程？

You can do this with a relatively simple polygon overlay. You'll need to obtain polygon data for each region of interest from a third party since the API does not provide any.
你可以用一个相对简单的多边形覆盖来做到这一点。您需要从第三方获取每个感兴趣区域的多边形数据，因为 API 不提供任何数据。
On zooming in to region state names will be shown, no city name should be visible either I zoom in or out.
在放大到区域状态名称时将显示，无论是放大还是缩小，都不应看到城市名称。
This starts to get more complicated. Probably best done using a custom map type(see image map types) if you don't want to see features like city names.
这开始变得更加复杂。如果您不想看到像城市名称这样的特征，最好使用自定义地图类型（请参阅图像地图类型）。
