OpenStreetMapLayer
OpenStreetMap （中文名：开源街景地图）是一种开源的世界地图，一种任何人都可以编辑的地图。
OpenStreetMapLayer 是一个图层类，用于加载开源街景地图来作为底图。
关于 OpenStreetMapLayer API 查阅：https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-OpenStreetMapLayer.html
这个示例显示了如何添加 OpenStreetMap 到三维地图。
程序完整源代码：

"esri/Map",
"esri/views/SceneView",
"dojo/dom",
"dojo/domReady!"
], function(
OpenStreetMapLayer,
Map,
SceneView,
dom) {
var map = new Map({
ground: "world-elevation"
});
var view = new SceneView({
map: map,
container: "viewDiv"
});
var osmLayer = new OpenStreetMapLayer();
map.add(osmLayer);
});
