KML + Google地球：制作多边形或GroundOverlay可点击吗？

Question

很简单的问题。

我有一些在KML中定义的多边形和GroundOverlay。有没有办法指定它们应该是可点击的，并且（至少在Google Earth中）在点击时弹出信息框或类似信息？

同样，是否可以给多边形/ GroundOverlays任何类型的鼠标悬停行为？例如更换图标或颜色时被挖空？

Answer 1

是的。为地标提供名称和说明将使其成为Google地球中的可点击对象，并将打开一个显示两者的信息窗口。您可以使用样式地图创建翻转/鼠标悬停行为，下面是两个示例：

<?xml version="1.0" encoding="UTF-8"?> 
<kml xmlns="http://www.opengis.net/kml/2.2"> 
<Document> 
<name>Highlighted Icon</name> 
<description>Place your mouse over the icon to see it display the new 
     icon</description> 
<StyleMap id="exampleStyleMap"> 
    <Pair> 
    <key>normal</key> 
    <!-- you could also use a <styleUrl> here instead of inlining --> 
    <Style> 
     <PolyStyle> 
     <color>7dff0000</color> 
     </PolyStyle> 
    </Style> 
    </Pair> 
    <Pair> 
    <key>highlight</key> 
    <!-- you could also use a <styleUrl> here instead of inlining --> 
    <Style> 
     <PolyStyle> 
     <color>7dffffff</color> 
     </PolyStyle> 
    </Style> 
    </Pair> 
</StyleMap> 

<!-- and now, a Placemark that uses the StyleMap --> 
<Placemark> 
    <name>Roll over this polygon</name> 
    <description>this will show up when clicked</description> 
    <visibility>1</visibility> 
    <styleUrl>#exampleStyleMap</styleUrl> 
    <Polygon> 
    <tessellate>1</tessellate> 
    <altitudeMode>absolute</altitudeMode> 
    <outerBoundaryIs> 
     <LinearRing> 
     <coordinates>
