在Google地球中，我的气球打开时没有指向我线上的正确位置。他们正在等待。我读了一些地方，可以通过在多几何地标上添加一个点来修复这个问题，它会指向那个地方。但它不起作用！有没有解决这个问题？我正在使用mac和Google Earth 7.1
谢谢， 艾伦

答案 0 :(得分：0)
将气球放置在地图上的锚点计算为要素中几何的中心点。对于您的示例中的MultiGeometry，它是线的中心和点的组合。线条的范围使中心偏向右边。
如果您希望气球锚定在该点，则将 LineString 移动到第二个功能。
您可以通过向根级别文档添加{em> checkHideChildren 类型ListStyle来隐藏您有两个功能而不是一个功能，以隐藏这些子功能：
<Document>
<name>KmlFile</name>
<styleUrl>#checkHide</styleUrl>
<Style id="checkHide">
<ListStyle>
<listItemType>checkHideChildren</listItemType>
</ListStyle>
