如何找到Google地图的经纬度

Post by indream, 2009-10-14, Views:

Google地图(http://maps.google.com/)上并没有显示某个地址的经纬度,实际上,我们已经想到了一个办法,可以找到在谷歌地图上任意地点的经度和纬度。

首先打开Google地图,在上面寻找一个地址,然后上下左右移动地图,让这个地址正好处于地图的正中心位置,当您想寻找坐标位置已经处于地图的中心位置的时候,拷贝并粘贴以下代码到你的浏览器地址栏:



javascript:void(prompt('',gApplication.getMap().getCenter()));



这时,你将得到一个弹出式的坐标,这个坐标就是你需要找的经度和纬度。
