《Cesium 进阶知识点》 - 加载天地图三维地名服务（无Cesium 版本依赖）
一、解决依赖
天地图官网说只支持 1.52、1.58、1.63.1 这 3个版本，其它版本报错。但我只使用三维地名服务。所以做了如下修改。
我在 1.80 版 和 1.84 版中测试有效。操作部署是：
1. 根据官网安装 cesium-tdt 插件；
2. 将 node_modules\cesium-tdt\dist\cesiumTdt.js 文件拷贝出来。使用script标签方式引入。
但报如下错误。
找到错误位置，与可用的 1.58 版做对比，发现将 cesiumTdt.js 做如下修改即可：
e[P("0x71")](this[P("0xa4e")])?this[P("0xa4e")]=this[P("0xa4e")].slice():e[P("0x14")](this[P("0xa4e")])&&0将上面一行代码找到，替换成下面即可。有点简单粗暴，但亲测有效。。。
this[P("0xa4e")]=['0','1','2','3','4','5','6','7']二、实现
添加
// 天地图 token（这是乱写的，请自己申请）
var token = '3f2332132139e8c21af5e34a25ef0dc88';
// 服务域名
var tdtUrl = 'https://t{s}.tianditu.gov.cn/';
// 服务负载子域
var subdomains=['0','1','2','3','4','5','6','7'];
// 叠加三维地名服务
var wtfs = new Cesium.GeoWTFS({
viewer,
subdomains:subdomains,
metadata:{
boundBox: {
minX: -180,
minY: -90,
maxX: 180,
maxY: 90
},
minLevel: 1,
maxLevel: 20
},
aotuCollide: true, //是否开启避让

serverFirstStyle: true, //服务端样式优先

});
//三维地名服务，使用wtfs服务
wtfs.getTileUrl = function(){
return tdtUrl + 'mapservice/GetTiles?lxys={z},{x},{y}&tk='+ token;
}
// 初始化
wtfs.initTDT([{"x":6,"y":1,"level":2,"boundBox":{"minX":90,"minY":0,"maxX":135,"maxY":45}},{"x":7,"y":1,"level":2,"boundBox":{"minX":135,"minY":0,"maxX":180,"maxY":45}},{"x":6,"y":0,"level":2,"boundBox":{"minX":90,"minY":45,"maxX":135,"maxY":90}},{"x":7,"y":0,"level":2,"boundBox":{"minX":135,"minY":45,"maxX":180,"maxY":90}},{"x":5,"y":1,"level":2,"boundBox":{"minX":45,"minY":0,"maxX":90,"maxY":45}},{"x":4,"y":1,"level":2,"boundBox":{"minX":0,"minY":0,"maxX":45,"maxY":45}},{"x":5,"y":0,"level":2,"boundBox":{"minX":45,"minY":45,"maxX":90,"maxY":90}},{"x":4,"y":0,"level":2,"boundBox":{"minX":0,"minY":45,"maxX":45,"maxY":90}},{"x":6,"y":2,"level":2,"boundBox":{"minX":90,"minY":-45,"maxX":135,"maxY":0}},{"x":6,"y":3,"level":2,"boundBox":{"minX":90,"minY":-90,"maxX":135,"maxY":-45}},{"x":7,"y":2,"level":2,"boundBox":{"minX":135,"minY":-45,"maxX":180,"maxY":0}},{"x":5,"y":2,"level":2,"boundBox":{"minX":45,"minY":-45,"maxX":90,"maxY":0}},{"x":4,"y":2,"level":2,"boundBox":{"minX":0,"minY":-45,"maxX":45,"maxY":0}},{"x":3,"y":1,"level":2,"boundBox":{"minX":-45,"minY":0,"maxX":0,"maxY":45}},{"x":3,"y":0,"level":2,"boundBox":{"minX":-45,"minY":45,"maxX":0,"maxY":90}},{"x":2,"y":0,"level":2,"boundBox":{"minX":-90,"minY":45,"maxX":-45,"maxY":90}},{"x":0,"y":1,"level":2,"boundBox":{"minX":-180,"minY":0,"maxX":-135,"maxY":45}},{"x":1,"y":0,"level":2,"boundBox":{"minX":-135,"minY":45,"maxX":-90,"maxY":90}},{"x":0,"y":0,"level":2,"boundBox":{"minX":-180,"minY":45,"maxX":-135,"maxY":90}}]);删除
wtfs.destroy();透明度
// 字体透明度设置。但注意这是在加完之后才能设置，没有找到加载完的回调loaded方式。刚加载时wtfs.labelCache是空数组
wtfs.labelCache.forEach(entity => {
entity.label.fillColor = entity.label.fillColor.getValue().withAlpha(alpha/100);
entity.label.outlineColor = entity.label.outlineColor.getValue().withAlpha(alpha/100);
});三、效果
四、注意
如果加载完成发现标注被遮挡，请这样设置
// 关闭地形深度检测
viewer.scene.globe.depthTestAgainstTerrain = false;五、隐藏
