随着GNSS卫星定位应用的普及和计算机、数据通信及互联网络(LAN/WAN)等技术的日益成熟,连续运行参考站系统(CORS)应运而生。各个省市都建立了全省或者以地市为单位的CORS系统。利用CORS站来测量各种比例尺地形图的方法逐渐被测量单位所采用,这是测量应用方面的一次重要变革。本文主要阐述了CORS系统的概念、组成和使用,提出对利用CORS站测量出的地形图精度的检测方案,并通过实际项目进行检测,得出数字化地形图精度结论。
隨著GNSS衛星定位應用的普及和計算機、數據通信及互聯網絡(LAN/WAN)等技術的日益成熟,連續運行參攷站繫統(CORS)應運而生。各箇省市都建立瞭全省或者以地市為單位的CORS繫統。利用CORS站來測量各種比例呎地形圖的方法逐漸被測量單位所採用,這是測量應用方麵的一次重要變革。本文主要闡述瞭CORS繫統的概唸、組成和使用,提齣對利用CORS站測量齣的地形圖精度的檢測方案,併通過實際項目進行檢測,得齣數字化地形圖精度結論。

With the popularity of GNSS satellite positioning application and the development of computer,data communications and the Internet(LAN/WAN),Continuously Operating Reference Station System(CORS)came into being.Various provinces and municipalities had established their CORS system.It's a significant change on the application of survey and mapping that CORS station had been gradually adopted in various scales of topographic maps.The concept、components and applications of CORS system were elaborated in this paper.It proposed the detection program of topographic maps by CORS,and draw the accuracy conclusion of digital topographic maps by testing practical projects.
