    style.getIconStyle().getHotSpot().set(0.5, ge.UNITS_FRACTION, 0, ge.UNITS_FRACTION);
    icon.setHref('https://xyz.jpg');

   // alert(lat);
    var pt = ge.createPoint('');

    pt.set(lat, lng, alt, altMode, false, false);
    //dummy copying below
    LAT=lat; // THE VALUES TO BE SAVED IN XML
    LON=lng; // THE VALUES TO BE SAVED IN XML
