Cesiumjs 获取坐标点高度的三种方式[转]

第一种（镜头高度太高获取的高度会为错误的负数，镜头高度要足够低）

let cartographic = Cesium.Cartographic.fromDegrees(lon,lat);
let height = viewer.scene.globe.getHeight(cartographic);

第二种（获取屏幕坐标点高度）

let scene = viewer.scene; let globe = scene.globe; let ray = viewer.camera.getPickRay(position);//position屏幕坐标 let cartesian = globe.pick(ray, scene); let ellipsoid = Cesium.Ellipsoid.WGS84; let cartographic = ellipsoid.cartesianToCartographic(cartesian); let height = cartographic.height; 

第三种（要11级? 不然获取不到）

let cartographics= [Cesium.Cartographic.fromDegrees(lon,lat)]; Cesium.sampleTerrain(viewer.terrainProvider, 11, cartographics) .then((updatedPositions)=>{ updatedPositions.forEach((pos, i) => { console.log(pos) }); });
