我想你在找这个:

的例子:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
  <Folder>
    <name>Network Links</name>
    <visibility>0</visibility>
    <open>0</open>
    <description>Network link example 1</description>
    <NetworkLink>
      <name>Random Placemark</name>
      <visibility>0</visibility>
      <open>0</open>
      <description>A simple server-side script that generates a new random
        placemark on each call</description>
      <refreshVisibility>0</refreshVisibility>
      <flyToView>0</flyToView>
      <Link>
        <href>http://yourserver.com/map1.kml</href>
      </Link>
    </NetworkLink>
    <NetworkLink>
      <name>Random Placemark</name>
      <visibility>0</visibility>
      <open>0</open>
      <description>A simple server-side script that generates a new random
        placemark on each call</description>
      <refreshVisibility>0</refreshVisibility>
      <flyToView>0</flyToView>
      <Link>
        <href>http://yourserver.com/map2.kml</href>
      </Link>
    </NetworkLink>
  </Folder>
</kml>

Answer 2

你可以用Google Maps JS API来做。您需要使用google.maps.KmlLayer为每个KML文件创建覆盖层。

请看下面的例子:http://code.google.com/apis/maps/documentation/javascript/examples/layer-kml.html
