Unable to rotate kml layer

问题:

I want to rotate the kml layer in my map but it is not rotating however kml file contains the rotation tag. Here is KML file.

KML File

I am using this code to include the kml file.

var myLatLng = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 15,
    mapTypeId: google.maps.MapTypeId.SATELLITE,
    center: myLatLng
});

var ctaLayer = new google.maps.KmlLayer({
    url: 'https://s3.amazonaws.com/navizon.its.fp/1001/zk01w7hhv4_o.kml',
    map: map
});

回答1:

<rotation/> is not supported in KmlLayer, see https://developers.google.com/kml/documentation/kmlelementsinmaps for supported elements

回答2:

One option would be the third party KML parser geoxml3 which now supports the <GroundOverlay> <rotation> tag (with a change to the helper ProjectedOverlay library). (Disclaimer: I am currently the maintainer).

example with your KML

code snippet:

function initMap() {
  var map = new google.maps.Map(document.getElementById("map_canvas"), {
    center: {
      lat: 0,
      lng: 0
    },
    zoom: 0
  });
  infowindow = new google.maps.InfoWindow({});

  var geoXml = new geoXML3.parser({
    map: map,
    infoWindow: infowindow,
    singleInfoWindow: true,
  });
  geoXml.parseKmlString(kmlData);
}
google.maps.event.addDomListener(window, 'load', initMap);

var kmlData = '<?xml version="1.0" encoding="UTF-8"?><kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2"
