key= YOURAPIKEY" type="text/javascript"></script>
<script type="text/javascript">
var map;
var geoXml;
function init() {
if (GBrowserIsCompatible()) {
geoXml = new GGeoXml("http://path/to/your.kml");
map = new GMap2(document.getElementById("map_canvas"));
map.addOverlay(geoXml);
}
}
</script> ...
<body onload="init()">
<div id="map_canvas"></div>
...

15. <script src="http://www.google.com/jsapi?key=YOURAPIKEY"></script>
<script>
google.load('earth', '1');
var ge = null;
function init() {
google.earth.createInstance('map3d', initCallback, failureCallback);
}
function initCallback(pluginInstance) {
pluginInstance.getWindow().setVisibility(true);
addKmlFromUrl('http://path/to/your.kml');
}
function addKmlFromUrl(kmlUrl) {
var link = ge.createLink('');
link.setHref(kmlUrl);
var networkLink = ge.createNetworkLink('');
networkLink.setLink(link);
ge.getFeatures().appendChild(networkLink);
