Google Earth kml automatic refresh from server

In order to let Google Earth reload automatically from a server-based file, you have to make sure that the property "refreshInterval" is spelled as "refreshInverval".

For example:

  <?xml version="1.0" encoding="UTF-8"?>
  <kml xmlns="http://earth.google.com/kml/2.0">
    <NetworkLink>
      <name>Automatic server-based reload</name>
      <Url>
        <href>http://example.com/sample.kml</href>
        <refreshMode>onInterval</refreshMode>
        <refreshInverval>120</refreshInverval>
      </Url>
    </NetworkLink>
  </kml>
