1、獲取entity坐標及高程

var cartographic = Cesium.Cartographic.fromCartesian(entity.position.getValue());var lon = Cesium.Math.toDegrees(cartographic.longitude);var lat = Cesium.Math.toDegrees(cartographic.latitude);var elev = viewer.scene.globe.getHeight(cartographic);

2、鼠標點選獲取坐標及高程

var handler = new Cesium.ScreenSpaceEventHandler(viewer.scene.canvas); handler.setInputAction(function (event) {var wp = event.position;if (!Cesium.defined(wp)) {return}var ray = viewer.scene.camera.getPickRay(wp);if (!Cesium.defined(ray)) {return}var cartesian = viewer.scene.globe.pick(ray, viewer.scene);if (!Cesium.defined(cartesian)) {return}if (cartesian) {var cartographic = Cesium.Cartographic.fromCartesian(cartesian);var lon = Cesium.Math.toDegrees(cartographic.longitude);var lat = Cesium.Math.toDegrees(cartographic.latitude);var elev = viewer.scene.globe.getHeight(cartographic);}} }, Cesium.ScreenSpaceEventType.LEFT_CLICK);

3、根據坐標獲取高程

var carto=new Cesium.Cartographic.fromDegrees(lon,lat);　　//輸入經緯度 var h1=viewer.scene.globe.getHeight(carto);

4、根據坐標獲取地表附著物高程

var carto=new Cesium.Cartographic.fromDegrees(lon,lat)；　　//輸入經緯度 var h2=_this.viewer.scene.sampleHeight(carto);

?5、根據坐標獲取terrain高程，精度為m

var terrainData = new Cesium.CesiumTerrainProvider({url:this.server_url_outer+"terrain/" //輸入terrian地形數據加載地址 }); var positions = [Cesium.Cartographic.fromDegrees(lon,lat) //輸入經緯度 ]; var promise = Cesium.sampleTerrain(terrainData,positions); Cesium.when(promise, function (updatedPositions) {var terrainHeight = updatedPositions[0].height; });
