Google地球为什么改变KML多边形坐标？

Question

我的目标是能够使用KML文件在谷歌地球上定义的区域上绘制阴影多边形。我创建了一个带有一个地标和一个具有所需坐标的多边形的KML文档，并且可以将该文件导入Google My maps并显示该多边形。但是，当我用google earth打开同一个文件时，坐标似乎被解析得不同，多边形不正确（请参见图像）。在我的KML文件中是否存在导致Google地球执行此操作的内容？

这些是原始文件坐标。

<coordinates> 
    149.02126, -36.489864, 100 
    149.3816, -36.31477, 100 
    149.25783, -36.134285, 100 
    148.9647, -36.4074, 100 
    149.02126, -36.489864, 100 
</coordinates> 

如果我从谷歌地球复制多边形并粘贴到一个文本文件作为KML我得到以下坐标

<coordinates> 
    149.02126,-36.489864,100 
    149.3816,0,0 
    -36.31477,100,0 
    149.25783,-36.134285,100 
    148.9647,-36.4074,100 
    149.02126,-36.489864,100 
</coordinates>

你原来的KML坐标具有的元组，that is not valid（空格单独元组）空间。

<coordinates>149.02126, -36.489864, 100 149.3816, -36.31477, 100 149.25783, -36.134285, 100 148.9647, -36.4074, 100 149.02126, -36.489864, 100</coordinates> 

应该是：

<coordinates>149.02126,-36.489864,100 149.3816,-36.31477,100 149.25783,-36.134285,100 148.9647,-36.4074,100 149.02126,-36.489864,100</coordinates>
