谷歌地图与县覆盖？ [英] Google Maps with counties overlay?

问题描述

我没有使用Google地图的经验，但我想在我的web应用中嵌入选择您的县地图。我的应用程序只针对加利福尼亚州，所以它只需要支持一个州，但我找不到任何简单的方法来做到这一点（没有手动绘制所有郡县的重叠多边形）。

我假设我很容易在Google上找到Choose your county风格的界面示例，但我唯一发现的是这个 - http://maps.huge.info/county.htm - 我倾向于打他们的API来拉动整个几何体如果我找不到更好的选择，请说明状态。

有没有人有任何经验或见解来帮助简化这一过程？
< Google Fusion Tables现在链接到州，省，县和国会区的数据。

融合表的几何字段包含给定ob的Polygon元素JECT。他们的州边界多边形（在很小程度上是县）在少数几个地方看起来分辨率稍低，但对您而言可能已经足够好了，应该相对容易一些。

I have no experience working with Google Maps, but I'd like to embed a "Choose your county" map in my webapp. My app only targets California, so it only needs to support one state, but I can't find any easy way to do this (without manually drawing overlay polygons for all the county lines).

I assumed I'd easily be able to find examples of "Choose your county"-style interfaces on Google somehow, but the only thing I found was this -- http://maps.huge.info/county.htm -- and I'm leaning towards hitting their API to pull the geometry for the whole state if I can't find a better option.

Does anyone have any experience or insight to help make this a little easier?

解决方案

Google Fusion Tables now links to State, County, and Congressional District data for all of the US.

The geometry field of the fusion table contains a Polygon element for the given object. Their state boundaries polygons (and to a lesser extent the counties) look a little low resolution in a few places, but it may be good enough for you and should be relatively easy to grab.
