显示地图并突出显示某些国家/地区 [英] Display a map and highlight certain countries

问题描述

以下是我正在努力做的事：
在页面上显示地图（谷歌地图或任何竞争对手，免费是可能的...），并突出显示该地图上的某些国家（这些国家的名单

我尝试在地图上绘制多边形，其中包含（几乎）所有国家/地区的地理位置列表，但它太重。

有什么想法？

我相信你会需要一个多边形来做到这一点。

最后，还有Google Geochart

Here's what I'm struggling to do : Display a map on page (Google map or any of it competitors, free is possible...) and highlight certain countries on this map (the list of theses countries would be stored in a variable by exemple).

I tried to draw polygons on the map with a geo-json list of (almost) all the countries but it's too heavy.

Any ideas ?

解决方案

I believe you will need a polygon to do that.

like this sample: http://gmaps-samples-v3.googlecode.com/svn/trunk/poly/pentagon.html
