非常简单的问题。
我在KML中定义了一些Polygons和GroundOverlays。有没有办法指定它们应该是可点击的,并且(在Google地球中,至少)点击它们时会弹出信息气球或类似信息?
同样,是否可以为polygons / GroundOverlays提供任何类型的鼠标悬停行为?例如鼠标悬停时更改图标或颜色?
答案 0 :(得分:10)
是。为地标添加名称和说明会使其成为Google地球中的可点击对象,并会打开一个显示两者的信息窗口。您可以使用样式图创建翻转/鼠标悬停行为,以下是两个示例:
<?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>
