Question

我想在地图中旋转kml图层，但它不旋转，但kml文件包含旋转标记。这是KML文件。

我正在使用此代码来包含kml文件。

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
});

Answer 1

KmlLayer不支持

<rotation/>，有关支持的元素，请参阅https://developers.google.com/kml/documentation/kmlelementsinmaps

Answer 2

一个选项是第三方KML解析器geoxml3，它现在支持<GroundOverlay> <rotation>标记（更改帮助程序ProjectedOverlay库）。（免责声明：我目前是维护者）。

example with your KML

代码段

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);
