Google Map中的边界 [英] Boundaries in Google Map

问题描述

我为我的网站使用Google地图，并且想要创建城镇边界，如下面的屏幕截图所示。

问题：在V3 API中似乎没有任何功能可以执行此功能。我相信它涉及检索在该区域周围形成多边形的路径的Latlng。
如何获得所需积分的Latlng？

解决方案

好的，假设您已经有了一条定义为Polyline的路径，那么您可以调用。getPath（）函数，它返回LatLng对象的MVCArray。我假设你的问题的答案是你怎么得到所需要的点数的？

I am using Google Maps for my website and I want to create boundaries of towns and cities, as shown in the screenshot below.

Problem: There seems not to be any feature in the V3 API to perform this function. I believe it involves retrieving the Latlng of the path that forms a polygon around the area. How then do you get the Latlng of the points needed?

解决方案

ok, assuming you already have a path defined as a Polyline, you can then call the .getPath() function which returns an MVCArray of LatLng objects. I assume that answers your question "How then do you get the Latlng of the points needed?"
