1.三维地图实现
在官网的demo中就有三维地图的实现，如下图所示
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">
<title>3D Map With Tianditu</title>
<style>
html, body, #viewDiv { padding: 0; margin: 0; height: 100%; width: 100%; }
</style>
<link rel="stylesheet" href="https://js.arcgis.com/4.5/esri/css/main.css">
<script type="text/javascript" src="https://js.arcgis.com/4.5/"></script>
<script type="text/javascript">
require(["esri/Map", "esri/views/SceneView", "dojo/domReady!"], function (Map, SceneView) {
var map = new Map({
"basemap": "satellite",
"ground": "world-elevation"
});
var view = new SceneView({
"map": map,
"scale": 500000,
"container": "viewDiv",
"center": [103.8000, 34.8000],
});
});
</script>

<div id="viewDiv"></div>

2.三维地图并叠加天地图
<!DOCTYPE html>

</style>
<link rel="stylesheet" href="https://js.arcgis.com/4.5/esri/css/main.css">
<script type="text/javascript" src="https://js.arcgis.com/4.5/"></script>
<script type="text/javascript">
require(["esri/Map",
"esri/config",
"esri/views/SceneView",
"esri/layers/TileLayer",
"esri/layers/WebTileLayer",
"dojo/domReady!"
], function (Map, esriConfig, SceneView, TileLayer, WebTileLayer) {
esriConfig.request.corsEnabledServers.push(
"t0.tianditu.com",
"t1.tianditu.com",
"t2.tianditu.com",
"t3.tianditu.com",
"t4.tianditu.com",
"t5.tianditu.com",
"t6.tianditu.com",
"t7.tianditu.com");
var map = new Map({
"ground": "world-elevation"
});
var view = new SceneView({
"map": map,
"scale": 500000,
"container": "viewDiv",
"center": [103.8000, 34.8000],
}); var layer = new TileLayer({
"url": "http://services.arcgisonline.com/arcgis/rest/services/World_Imagery/MapServer",
"copyright": "底图数据源：ESRI",
});
map.add(layer);
//map.add(tiledLayer);
var tiledLayer1 = new WebTileLayer({
"id": "Tianditu Id",
"title": "Tianditu Title",
"urlTemplate": "http://t{subDomain}.tianditu.com/DataServer?T=cva_w&x={col}&y={row}&l={level}",
"subDomains": ["0", "1", "2", "3", "4", "5", "6", "7"],
"copyright": "天地图地名"
});
map.add(tiledLayer1);
var tiledLayer2 = new WebTileLayer({
"id": "Tianditu Id",
"title": "Tianditu Title",
"urlTemplate": "http://t{subDomain}.tianditu.com/DataServer?T=ibo_w&x={col}&y={row}&l={level}",
"subDomains": ["0", "1", "2", "3", "4", "5", "6", "7"],
"copyright": "天地图边界"
});
map.add(tiledLayer2);
});
</script>
</head>
<body>
<div id="viewDiv"></div>
</body>
</html>
