它可以在谷歌地球和地图，无论我尝试的多边形不填。有没有办法填补他们？谢谢。

出于某种原因，你有一个outerBoundaryIs和innerBoundaryIs是相同的。内部边界通常只用于具有“圆环孔”的情况，但在这种情况下，您的“孔”（正好）与多边形本身一样大，因此它看起来像一个未填充的多边形。你需要摆脱“innerBoundaryIs”。因此，例如在印尼多边形删除以下内容：

<innerBoundaryIs> 
    <LinearRing> 
    <coordinates>-90.61167907714844,-0.3755556046962738,0 -90.77166748046875,-0.344166785478592,0 -90.87222290039063,-0.2652778923511506,0 -90.79332733154297,-0.149444505572319,0 -90.77362060546876,-0.1550000011920929,0 -90.58556365966797,-0.2455555945634842,0 -90.55029296875,-0.3091666996479035,0 -90.61167907714844,-0.3755556046962738,0</coordinates> 
    </LinearRing> 
</innerBoundaryIs> 

你还应该增加一个镶嵌，因为这些都是非常大的多边形，你希望他们按照地球的曲率...即。在“Polygon”之后使用“tessellate”（它可以是1或0，用于打开或关闭）。最后，你想你的高度模式为“clampedToGround”

我认为这是你在找什么：
