Mozilla export coordinates to a .kml file (for Google Earth)

to google javascript mozilla xml convert maps kml geo by pwlin on Apr 28, 2008

Usage:

// define a location hash:
var location = {
    'name':'Tokyo',
    'latitude':35.65444,
    'longitude':139.74472
    // Other data: 
    //'heading' : 0 ,
    //'tilt' : 0 ,
    //'range':  1000000 
}
// choose a name for your .kml file:
var myFileName = 'my_geo.kml';

// now use them to force opening a .kml file:
$google.openKMLFile(location,myFileName);

Will output:

<?xml version="1.0" encoding="UTF-8" ?> 
<kml xmlns="http://earth.google.com/kml/2.0">
<Document>
<Placemark>
<name>Tokyo</name> 
<Point>
<altitudeMode>relativeToGround</altitudeMode> 
<coordinates>139.74472,35.65444,0</coordinates> 
</Point>
<LookAt>
<heading>0</heading> 
<tilt>0</tilt> 
<range>1000000</range> 
<latitude>35.65444</latitude>
