前言
往往好多事情是需求推動的，正好一個網友在群里問到”怎么讓Cesium加載GeoJSON的白膜并貼在地形上？“，聯系到他，要了他的數據，完成了代碼并測試通過。正好出差，而且一個人工作之余無事（加之西寧不知咋搞的，賓館旁的市政作業挖掘機22:35還不歇息，可謂是驚天動地啊），通過從數據的獲取到加載進行研究并作出記錄，希望能幫到更多的人！
1. QGIS離線GeoJSON白膜數據
《QGIS離線數據或瓦片并使用Cesium調用離線瓦片》已經寫了相關內容，可惜當時未導出GeoJSON數據，此次基本按照當時得操作步驟進行數據離線。將重要數據作為記錄。
- 打開OpenStreetMap，框選下載數據，移除相關不相關數據
- 將其導出為GeoJSON
- 移除非相關的面狀要素，右鍵Toggle Editing,刪除院子等面狀要素，然后save
- 添加樓層floor字段，并編輯所有數據，至此制作完成
2. Cesium加載并根據樓層高度拉伸
