3. kml文件调用方式以及文件对象的创建

  var kmlOptions = {
    camera: viewer.scene.camera,
    canvas: viewer.scene.canvas,
    // 如果我们想要将几何特征（多边形、线串和线性环）固定在地面上，则为 true。
    clampToGround: true
  };
  var geocachePromise = Cesium.KmlDataSource.load('./assets/SampleData/sampleGeocacheLocations.kml', kmlOptions);

4. 将 geocache 广告牌实体添加到场景中并为其设置样式

  // 将 geocache 广告牌实体添加到场景中并为其设置样式
  geocachePromise.then(function (dataSource) {
    // 将新数据作为实体添加到查看器
    viewer.dataSources.add(dataSource);

    // 获取实体数组
    var geocacheEntities = dataSource.entities.values;

    for (var i = 0; i < geocacheEntities.length; i++) {
      var entity = geocacheEntities[i];
      if (Cesium.defined(entity.billboard)) {
        // 调整垂直原点，使图钉位于地形上
        entity.billboard.verticalOrigin = Cesium.VerticalOrigin.BOTTOM;
        entity.billboard.image = '/assets/tagpark.png'
        // 禁用标签以减少混乱
        entity.label = undefined;
        // 添加距离显示条件
        entity.billboard.distanceDisplayCondition = new Cesium.DistanceDisplayCondition(10.0, 20000.0);
        // 以度为单位计算纬度和经度
        var cartographicPosition = Cesium.Cartographic.fromCartesian(entity.position.getValue(Cesium.JulianDate.now()));
        var latitude = Cesium.Math.toDegrees(cartographicPosition.latitude);
        var longitude = Cesium.Math.toDegrees(cartographicPosition.longitude);
        // 修改描述
        var description = ''+''+''+''+''+'
 
          
' + "Longitude" + '
' + longitude.toFixed(5) + '
 
          
' + "Latitude" + '
' + latitude.toFixed(5) + '
 
          
' + "实时人流" + '
' + Math.floor(Math.random() * 20000) + '
 
          
' + "安全等级" + '
' + Math.floor(Math.random() * 5) + '
 
          
';
        entity.description = description;
      }
    }
  });
