随着CORS测量在城市测量中的广泛应用,CORS外业检核测量对保障成果的精度显得非常重要。可选择已有的城市导线点作为检测点,但城市导线点由于起算系统等原因,与城市CORS系统往往存在系统误差。文中介绍楼顶CORS外业检核点建设方法以及数据处理方法,保证CORS检核点成果与城市CORS系统的一致性,为相关生产提供借鉴。
隨著CORS測量在城市測量中的廣汎應用,CORS外業檢覈測量對保障成果的精度顯得非常重要。可選擇已有的城市導線點作為檢測點,但城市導線點由于起算繫統等原因,與城市CORS繫統往往存在繫統誤差。文中介紹樓頂CORS外業檢覈點建設方法以及數據處理方法,保證CORS檢覈點成果與城市CORS繫統的一緻性,為相關生產提供藉鑒。

With CORS measurement widely used in the city as well as the acceleration of urban construction ,it is very important for the field measurements that influences the results .Because of the traditional starting point of the city wire systems and other reasons ,the city CORS system may exist systematic errors .In this paper ,in order to ensure the results of testing stations and city CORS system consistency and reliability ,the rigorous checklist adjustment methods are proposed ,w hich can for other provide a reference domestic production units .
